Description

Technical Field

[0001] This invention relates to a pallet production equipment, and more particularly to a pallet assembly production apparatus. Background Technology

[0002] As a type of containerized equipment similar to shipping containers, pallets are now widely used in production, transportation, warehousing, and distribution, and are considered one of the two key innovations in the 20th-century logistics industry. Pallets, as important loading, unloading, storage, and transportation equipment in logistics operations, play a significant role in modern logistics when used in conjunction with forklifts. The benefits pallets bring to modern logistics are mainly reflected in: enabling unitized, standardized, and regulated packaging of goods, protecting goods, and facilitating logistics and commerce. Pallets are also known as skids or pallets. Pallets can be categorized into at least two types based on their function: one is the everyday pallet used to hold bowls and dishes when serving food; the other is the logistics pallet used for everyday tasks such as placing plates and bowls. Logistics pallets are further differentiated by material, purpose, platform, forklift entry method, and structure, resulting in various types of pallets. Especially in situations requiring rapid operations, pallet usage is increasing due to their high efficiency and safety. Wooden pallets are relatively inexpensive, but because they may harbor insects and eggs, potentially disrupting the ecological balance of the importing country and leading to biological invasions, fumigation and pest control are necessary when exporting (or importing) to some countries. Because fumigation and detoxification take time, some cargo owners sometimes choose other fumigation-free pallets. Paper pallets are a good alternative to wooden pallets that do not require fumigation. However, since the paper pallet industry developed relatively late, much of its production relies on manual assembly, which is labor-intensive and inefficient. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a pallet assembly and production device with a simple structure, reasonable design, and a pallet that can move up and down, thereby improving production efficiency. The use of a positioning frame also improves work efficiency, avoids human error, and enhances product quality.

[0004] To achieve the above objectives, the present invention includes the following technical solution: a frame is provided, the frame including columns and a portal frame; a pallet frame is provided between the columns, the pallet frame is provided with a pallet, and a longitudinal sprocket and chain mechanism is provided between the columns and the pallet frame for the pallet frame to move up and down; a positioning frame is hinged to the rear end of the portal frame to position the base block on the panel of the pallet; a cylinder is provided between the columns and the positioning frame to lift the positioning frame to facilitate the placement of the panel on the pallet.

[0005] Specifically, the present invention is a pallet assembly production device, including a base, a frame provided on the base, a pallet movably connected to the frame, a drive mechanism for the pallet to move up and down between the frame and the pallet; a positioning frame for positioning the pallet's foot blocks is provided on the top of the frame, and the positioning frame covers the pallet.

[0006] The frame includes columns mounted on the base, the columns are positioned on the left and right sides, and a flat portal frame is mounted on the top of the column. The portal frame is connected to the column on both sides and has an opening at the front end.

[0007] Furthermore, the rear end of the positioning frame is hinged to the rear end of the gate frame via a hinge joint, the positioning frame is provided with a positioning rod for positioning the base block, and the positioning rod is provided with a positioning block for positioning the base block.

[0008] Furthermore, a guide rail is provided on the inner side of the column. The guide rail is grooved, and a sprocket and chain mechanism is longitudinally arranged in the groove of the guide rail. The chain of the sprocket and chain mechanism is fixedly connected to a pin. A tray frame is movably connected to the pin. The tray frame has a tray on its top and a bearing that mates with the pin on its side. Guide wheels that mate with the guide rail are provided on the left and right sides of the tray frame.

[0009] Furthermore, a motor is provided on the outside of the column, and the motor is connected to the sprocket shaft at the lower end of the sprocket and chain mechanism.

[0010] Furthermore, a horizontal axis is provided on the side of the positioning frame, a cylinder is provided on the outside of the column, the tail of the cylinder is hinged to the column, and the top of the piston rod of the cylinder is movably connected to the positioning frame through the horizontal axis.

[0011] Furthermore, a connecting block is provided at the top of the piston rod of the cylinder, and the connecting block is provided with an elongated guide hole that cooperates with the horizontal axis.

[0012] Furthermore, the left and right sides of the positioning frame are hollow structures, and the upper side of the left and right sides is provided with elongated holes. The positioning frame is bolted to the positioning rod through the elongated holes. The tail of the positioning block is provided with a transverse groove, which is engaged with the positioning rod. A clamping bolt is provided on the side of the tail of the positioning block at the transverse groove.

[0013] Furthermore, a button control mechanism is provided at the left front end of the gate-shaped frame.

[0014] Furthermore, the column is equipped with a limit switch.

[0015] During operation, the operator manipulates the button control mechanism to raise the positioning frame, allowing the operator to place the pallet panel onto the pallet. The operator then manipulates the button control mechanism again to lower the positioning frame, allowing the operator to place pallet feet onto the pallet panel. Once the pallet feet are in place, the operator manipulates the button control mechanism again, causing the motor to drive the sprocket and chain mechanism to lower the pallet frame. The motor stops when the limit switch detects the pallet panel. This process is repeated.

[0016] When the pallet rack descends to its lowest position, the workers lift out all the assembled pallets, then operate the button control mechanism to raise the pallet rack to its highest position, and repeat the above steps.

[0017] The beneficial effects of this solution, as described above, are evident in its simple structure and reasonable design. The use of vertically movable pallets eliminates the need to assemble and remove pallets one by one, improving production efficiency. The positioning frame eliminates the need for manual measurement and positioning, significantly reducing manpower consumption and improving work efficiency. Furthermore, it standardizes the arrangement of pallet base blocks, avoiding human error and improving product quality. The frame structure, with columns positioned horizontally and horizontally, and a square portal frame at the top of the columns, facilitates observation of the area below the frame. A sprocket and chain mechanism drives the pallet frame, allowing for the cumulative stacking of assembled pallets, preventing the need to remove them one by one and further improving production efficiency. A horizontal axis is located on the side of the positioning frame, and a cylinder on the column is movably connected to the horizontal axis, controlling the lifting and lowering of the positioning frame for easy panel placement. A long guide hole is provided at the top of the cylinder piston rod, reducing the possibility of interference between moving parts. The positioning frame has elongated holes on both sides for bolting to the positioning rods. A transverse groove is located at the tail of the positioning block, engaging with the positioning rod to facilitate adjustment of the positioning rod and block positions. A button control mechanism is located on the front left side of the portal frame for easy operation. Limit switches are installed on the columns to ensure standardized descent distances for each pallet rack. Attached Figure Description
