Description

Technical Field

[0001] This utility model relates to the field of silo technology, and in particular to a special silo for storing workpieces that is adapted to automatic feeding of machine tools. Background Technology

[0002] In the field of machining technology, machine tool processing is a common processing method. When using machine tools, the workpiece to be processed needs to be mounted on the machine tool's worktable, and after processing, the machined workpiece is removed from the worktable. Manual loading and unloading is inconvenient, especially for large and heavy workpieces, where manual loading and unloading is very costly and may even require multiple people to cooperate, resulting in high labor costs. To reduce labor costs, palletizers are used for automatic loading in some scenarios. Palletizers require the use of specialized hoppers, and currently common hoppers are not compatible with the automatic loading and unloading of workpieces by palletizers. Utility Model Content

[0003] To address the aforementioned problems in the prior art, this utility model provides a special workpiece storage bin adapted for automatic loading of machine tools. This special bin has a stable structure, and after storing workpieces, it can be automatically loaded and unloaded by a palletizer, greatly improving the processing efficiency of the machine tool.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A dedicated workpiece storage bin adapted for automatic loading of machine tools includes at least one bin body. The bin body has several longitudinally distributed storage cavities. Each storage cavity has a support frame at its bottom. The support frame has a tray assembly for mounting workpieces. The bottom of the tray assembly has a positioning seat for direct docking and positioning with the machine tool's worktable. Each storage cavity has a front channel on its front side for the tray assembly to enter and exit the storage cavity.

[0005] By adopting the above technical solution: the workpiece is installed on the pallet assembly, the pallet assembly is installed on the support frame of the storage cavity, and the pallet assembly and the workpiece are directly transferred to the machine tool's worktable by the palletizer. The pallet assembly directly docks with the machine tool's worktable and is then processed. After processing, the pallet assembly and the processed workpiece are transferred together to the support frame of the storage cavity by the palletizer on the machine tool's worktable. Through this special hopper, the palletizer can directly realize the automatic loading and unloading of the machine tool, thereby improving the processing efficiency of the machine tool.

[0006] Preferably, the hopper body has a cuboid frame structure, and the hopper body is made of several square tubes connected together; each storage cavity has several crossbeams at its bottom, and the support frame is installed on the crossbeams; each storage cavity has a rear channel for installing workpieces on its rear side. The palletizer picks up and places pallet assemblies through the front channel, and a person passes through to install and remove workpieces.

[0007] Preferably, the support frame has bracket seats at both ends, and the bracket seats are bolted to the top surface of the crossbeam. The top surface of the bracket seats has several positioning posts that are plugged into the positioning seats. When the pallet assembly is connected to the positioning posts on the support frame, a fork passage for the palletizer's forks is formed between the bottom surface of the pallet assembly and the bottom surface of the storage cavity. The palletizer's forks can directly extend into the fork passage to pick up the pallet assembly and the workpiece together and transfer them to the machine tool's worktable.

[0008] Preferably, at least two hopper bodies are configured, arranged side by side laterally, sharing the same side; each hopper body has a base at its lower end for fixed connection to the ground. Depending on actual processing needs, two or more hopper bodies can be configured to store more workpieces.

[0009] Preferably, the lower front end of the hopper body is provided with an upward-opening water trough, and the bottom of each storage chamber is provided with a guide plate that is inclined from front to back. When the cooling water remaining on the pallet assembly flows onto the guide plate, the cooling water flows into the water trough along the guide plate. When the pallet assembly and the workpiece are processed together, the cooling water on the machine tool cools the workpiece, so some cooling water will remain on the workpiece and the pallet assembly. When the pallet assembly is transferred to the storage chamber, the cooling water will flow into the water trough along the guide plate, thereby keeping the ground around the hopper clean and preventing cooling water from polluting the ground environment.

[0010] Preferably, the bottom of the pallet assembly is provided with a plurality of pin seats for connecting with the fork carriage at the corresponding position of the fork carriage channel, and the pin seats are provided with pin holes. When the fork carriage picks up the pallet assembly, the pin holes on the bottom of the pallet assembly cooperate with the pins on the fork carriage for positioning.

[0011] Preferably, the front side of the pallet assembly is provided with a chip for storing workpiece processing information. A card reader on the palletizer's fork reads the chip information, thereby moving the pallet assembly to the corresponding machine tool.

[0012] Therefore, this utility model has the beneficial effect of being able to work with a palletizer to directly load and unload materials from machine tools and improve the processing efficiency of machine tools. Attached Figure Description

[0017] To make the technical problem to be solved, the technical solution, and the beneficial technical effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the scope of protection of the present utility model.

[0018] It should be understood that the terms "first," "second," etc., used herein are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor should they be construed as implicitly specifying the number of technical features indicated. Features specified as "first" or "second" may expressly or implicitly indicate that at least one of those features is included.

[0019] like Figures 1-4 The workpiece storage bin shown is adapted for automatic feeding of machine tools and includes at least one bin body 1. The bin body 1 has several longitudinally distributed storage cavities 100. Each storage cavity 100 has a support frame 2 at its bottom. The support frame 2 has a tray assembly 3 for mounting workpieces. The bottom of the tray assembly 3 has a positioning seat 31 for direct docking and positioning with the worktable of the machine tool. The front side of each storage cavity 100 has a front channel 101 for the tray assembly 3 to enter and exit the storage cavity 100.

[0020] The hopper body 1 has a rectangular frame structure and is made of several square tubes connected together. Each storage cavity 100 has several crossbeams 11 at its bottom, and the support frame 2 is installed on the crossbeams 11. Each storage cavity 100 has a rear channel 102 for installing workpieces on its rear side. The support frame 2 has bracket seats 21 at both ends. The bracket seats 21 are bolted to the top surface of the crossbeams 11. The top surface of the bracket seats 21 has several positioning posts 22 that are inserted and connected to the positioning seats 31. When the pallet assembly 3 is connected to the positioning posts 22 on the support frame 2, a fork passage 103 for the pallet assembly 3 and the storage cavity 100 to enter and exit is formed between the bottom surface of the pallet assembly 3 and the bottom surface of the storage cavity 100.

[0021] In some embodiments, at least two hopper bodies 1 are configured, arranged side-by-side laterally, sharing the same side; each hopper body 1 has a base 12 at its lower end for fixed connection to the ground. In this embodiment, three hopper bodies are used, arranged side-by-side, with two storage cavities within each hopper body, meaning the entire hopper can store six workpieces. Depending on actual processing requirements, the number of hopper bodies or the number of storage cavities within each hopper body can be increased.

[0022] The lower front end of the hopper body 1 is provided with an upward-facing water trough 13, and the bottom of each storage chamber 100 is provided with a guide plate 14 that is inclined with a lower front and a higher rear. When the cooling water remaining on the tray assembly 3 flows onto the guide plate 14, the cooling water flows into the water trough 13 along the guide plate 14.

[0023] like Figure 3 As shown, the bottom of the pallet assembly 3, corresponding to the channel of the fork carriage 81, is provided with several pin seats 32 for connecting with the fork carriage 81, and each pin seat 32 has a pin hole 33. The front side of the pallet assembly 3 is provided with a chip 34 for storing workpiece processing information. When a workpiece is mounted on the pallet assembly, the processing information of the workpiece is written into the chip 34 on the corresponding pallet assembly. In this way, when the palletizer's fork carriage picks up the corresponding pallet assembly, it can read the information from the chip, thereby automatically transferring the workpiece to the corresponding machine tool for processing, further improving processing efficiency.

[0024] Referring to the accompanying drawings, the principle of this utility model is as follows: Figure 4 As shown, the palletizer 8 is installed on the front side of the hopper body 1. The fork 81 on the palletizer 8 extends from the front channel into the corresponding discharge chamber. The fork extends from the fork channel into the bottom of the pallet assembly. After the pin on the fork aligns with the pin hole at the bottom of the pallet assembly, the fork drives the pallet assembly to rise as a whole and then moves out from the front channel. The fork is equipped with a card reader for reading chip information. After the fork reads the processing information in the chip, it transfers the pallet assembly (along with the workpiece) to the corresponding machine tool for processing. Through this type of hopper, the workpiece and the pallet assembly are pre-installed. The palletizer transfers the pallet assembly and the workpiece together, thus eliminating the need for disassembly and assembly of the workpiece on the machine tool and greatly improving the processing efficiency of the workpiece.

[0025] In the description of this utility model, it should be understood that the directions or positional relationships indicated by up, down, left, right, inner end, outer end, one end, and the other end are based on the orientation or positional relationships shown in the accompanying drawings. They are only for the purpose of more clearly describing the technical solution of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as a limitation of this utility model.

[0026] Although specific embodiments of the present invention are described in detail herein, they are given for illustrative purposes only and should not be construed as limiting the scope of the present invention. Various substitutions, alterations, and modifications may be conceived without departing from the spirit and scope of the present invention.
