Description

Technical Field

[0001] The utility model relates to the technical field of production equipment, in particular to a pallet transfer device. Background Art

[0002] Currently, pallet stacking is primarily a manual process in the production process, a critical factor affecting overall production speed. Specifically, pallet stacking requires placing goods on pallets based on actual needs, then stacking them layer by layer using a forklift or manual labor, significantly increasing labor costs and time.

[0003] Existing manual pallet stacking methods have the following problems: First, manual stacking is relatively inefficient and prone to varying efficiency levels depending on operator proficiency, thus impacting overall production speed. Second, manual stacking is prone to errors, such as unstable or tilted stacks. As production scale expands and logistics speeds increase, manual pallet stacking can no longer meet the demands of efficient and stable production.

[0004] In summary, the current production process still relies mainly on manual labor to stack pallets, which undoubtedly limits the improvement of production cycle and affects the overall production efficiency of enterprises. Currently, there is a lack of a pallet transfer device that can solve or partially solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0042] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate the description of this utility model and simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it may be slightly tilted.

[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0044] Regarding the problems existing in the above-mentioned prior art, see Figure 1 This embodiment provides a pallet transfer device designed for applications requiring high stability and small payloads, such as cosmetic containers. The device primarily comprises a storage platform 1, a limiting frame 2, a slider 4, a movable rod 5, and a clamping claw. Each component is described below.

[0045] The platform 1 is provided with a station for placing pallets to be transferred. Pallets can be delivered to the station from an upstream assembly line or manually moved to the station. Preferably, a probe 16 is also connected to the platform 1. Probe 16 can be a commercially available photoelectric probe, infrared probe, or ultrasonic probe. Probe 16 is facing the station, and transfer begins when a pallet is placed.

[0046] The limiting frame 2 is connected to the storage platform 1. Slide rails 3 arranged along the X-axis are connected to either side of the limiting frame 2. This improves the stability of the pallet during transfer, but at the cost of limiting the device to pallet transfer within a specific area within the XY plane. In this embodiment, the limiting frame 2 is connected to the storage platform 1 via two support columns 8. A connecting plate 9 is provided between the support columns 8 and the storage platform 1. The connecting plate 9 has a T-shaped cross-section and mates with a pre-cut slot 10 along the Y-axis in the storage platform 1.

[0047] The slider 4 is movably connected to the slide rails 3 on both sides of the limit frame 2 to ensure better stability of the slider 4 when moving along the X direction. Specifically, considering the need for smooth movement, a commercially available screw (not shown) can be used to achieve movement of the slider 4 along the X direction.

[0048] The movable rod 5 is arranged along the Z-axis to achieve stable movement in the Z-direction. The movable rod 5 has a tooth groove 6, which is connected to the slider 4 via a motor 7. The motor drives the movable rod 5 to achieve stable movement in the Z-direction. Preferably, a guide rail 17 is further provided on one side of the movable rod 5 to further ensure the stability of the Z-direction movement.

[0049] The clamping claw is connected to one end of the movable rod 5 and matches the pallet to be transferred. Specifically, the clamping claw includes an extension frame 11 and a rectangular clamping module connected to the extension frame 11. The clamping module clamps both sides of the pallet to be transferred to optimize the success rate of clamping. The extension frame 11 is connected to one end of the movable rod 5 and is symmetrically arranged with clamping modules along the X-axis and Y-axis.

[0050] Each clamping module comprises a cylinder 12 connected to an extension frame 11, a piston rod 13 that mates with an opening in the cylinder 12, and a clamping block 14 that directly contacts the pallet during transport. One end of the clamping block 14 is bent to mate with the edge of the pallet being transported, and the other end is connected to the piston rod 13. Specifically, the cylinder 12 and piston rod 13 of this embodiment can be implemented using commercially available pneumatic or electric cylinders.

[0051] Taking into account that the air cylinder or electric cylinder on the YZ plane may be slightly out of sync, which may easily lead to the problem of clamping failure, the device is provided with a connecting block 15 to connect the piston rods 13 located on the same YZ plane, which alleviates the problem of out of sync to a certain extent.

[0052] See also Figure 2-Figure 6 Schematic diagram of the five positions of the pallet transfer device in a workflow.

[0053] See also Figure 2Before transfer, the connecting plate 9 is moved along the slot 10 to the desired transfer position and fixed. After fixation, the Y-axis coordinate of the clamping claw remains unchanged. After the empty pallet or pallet containing lightweight products to be transferred is placed at the workstation via the upstream assembly line or manually, transfer is initiated manually or by a probe 16. The screw rod is used to smoothly move the clamping claw to the top of the pallet to be transferred on the workstation.

[0054] See also Figure 3 The motor 7 is used to move the clamping claw steadily along the Z axis until the end of the clamping block 14 is located at the edge of the pallet, and the pneumatic cylinder / electric cylinder is used to synchronously clamp the pallet to achieve pallet fixation.

[0055] See also Figure 4 , use motor 7 to make the clamping claw lift steadily along the Z axis, and the pallet leaves the work station of the storage platform 1.

[0056] See also Figure 5 , using the screw rod, the clamping claw is smoothly moved to above the transfer target position (palletizing in this embodiment).

[0057] See also Figure 6 , use motor 7 to make the clamping claw move steadily along the Z axis, place the pallet at the target position, and complete the transfer of the pallet.

[0058] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
