DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is described below using specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0026] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0027] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] Example: Figures 1 to 6As shown, the turnover box code separator includes a column frame 1, a lifting mechanism 2, a fork mechanism 3 and an end blocking mechanism 4. The column frame 1 is assembled from multiple plates. The lifting mechanism 2 is installed on the column frame 1. The fork mechanism 3 is connected to the lifting mechanism 2. The fork mechanism 3 is moved up and down by the lifting mechanism 2 to realize the stacking and stacking of the turnover boxes 6. In order to limit the left and right of the turnover boxes 6 to improve the stacking efficiency, the end blocking mechanism 4 is installed on the side of the matching roller 5 and used in conjunction with the fork mechanism 3. The end blocking mechanism 4 includes an axial guide guardrail assembly and a longitudinal guide blocking assembly for realizing rapid separation between the upper and lower turnover boxes 6. The longitudinal guide blocking assembly is installed on the side of the axial guide guardrail assembly.

[0029] Specifically, the above-mentioned axial guide guardrail assembly includes a guide guardrail plate 4-1, a guide connecting plate 4-2 and a guide support plate 4-3. The above-mentioned guide connecting plate 4-2 is installed on the side of the above-mentioned guide guardrail plate 4-1, and the above-mentioned guide support plate 4-3 is installed on the above-mentioned guide connecting plate 4-2 and fixedly connected to the above-mentioned matching roller 5. In order to enhance the structural strength of the guide support plate 4-3, a guide support rib 4-4 is provided in the bent guide support plate 4-3. In this embodiment, there are two above-mentioned guide guardrail plates 4-1, which are respectively installed on both sides of the matching roller 5. The opening after the two above-mentioned guide guardrail plates 4-1 are combined is arranged in a trumpet shape, that is, it is arranged in a trumpet shape at the entrance of the turnover box 6. It is subsequently tightened, and the width of the tightening part is adapted to the width of the turnover box 6, thereby reducing the probability of the turnover box 6 being parked tilted. In order to enable the turnover box 6 to move downward under the action of the fork mechanism 3 and prevent the turnover box 6 from moving upward, that is, to achieve rapid separation between two adjacent turnover boxes 6, the above-mentioned longitudinal guide blocking assembly includes a pair of oppositely arranged fastener connecting plates 4-5 and fastener baffles 4-7, and a fastener shaft 4-6 is connected between the above-mentioned fastener connecting plates 4-5. The above-mentioned fastener baffle 4-7 is rotatably installed on the above-mentioned fastener shaft 4-6 and is located above the above-mentioned fastener shaft 4-6 and is fixed to the fastener baffle shaft 4-8. When in use, the fastener baffle 4-7 can rotate downward around the fastener shaft 4-6, that is, it is not The turnover boxes 6 are affected downward. When the code separator needs to stack the turnover boxes 6, the fastener baffle 4-7 is abutted against the side of the turnover box 6 located below, and then the lifting mechanism 2 drives the fork mechanism 3. The fork mechanism 3 extends the fork to the side of the turnover box 6 located above to achieve separation between the two turnover boxes 6. The above structural method makes the turnover box code separator in this embodiment highly automated, and does not require the operator to manually separate the upper and lower turnover boxes 6, thereby reducing the labor intensity of the operator and the labor cost, which is conducive to the promotion and application of the above turnover box code separator in the market.

[0030] In order to make the turnover box 6 bear the force evenly and ensure its stability during the stacking process, the above-mentioned longitudinal guide blocking components are divided into two groups. The two groups of the above-mentioned longitudinal guide blocking components are symmetrically arranged along the central axis of the matching roller 5. There are two fastener baffles 4-7 in each group of the above-mentioned longitudinal guide blocking components. A baffle connecting plate 4-9 is connected between the two above-mentioned fastener baffles 4-7. The baffle connecting plate 4-9 also has the function of maintaining the balance of the fastener baffles 4-7. The end face of the fastener baffle 4-7 is set obliquely downward to further reduce the impact on the turnover box 6 during the stacking process. The fastener baffle 4-7 is made of nylon material. Nylon material has high mechanical strength and good toughness. It has high tensile and compressive strength. It can effectively ensure the service life of the fastener baffle 4-7, reduce its replacement frequency, and thus reduce the cost of use.

[0031] In order to ensure the stability of the lifting mechanism 2 during use, the above-mentioned lifting mechanism 2 includes a lifting motor 2-1, a lifting drive shaft 2-2, a lifting chain 2-3, a lifting motor sprocket 2-4, a drive shaft sprocket 2-5, a shaft end sprocket 2-6, a clamp chain connecting plate 2-7, a chain redirecting wheel 2-8 and a lifting motor chain 2-10. The lifting motor 2-1 has high stability and is easy to use. Compared with the cylinder drive in the prior art, it can expand the application range of the code separator. The lifting motor sprocket 2-4 is mounted on the output end of the lifting motor 2-1, the drive shaft sprocket 2-5 is fixedly connected to the lifting drive shaft 2-2, and the lifting motor sprocket 2-4 and the drive shaft sprocket 2-5 are driven by the lifting motor chain 2-10, the shaft end sprocket 2-6 is mounted on the end of the lifting drive shaft 2-2 and is located on the column frame 1, the chain redirecting wheel 2-8 is mounted near the top of the column frame 1, and the shaft end sprocket 2-6 and the chain redirecting wheel 2-8 are driven by the lifting chain 2-3, and the lifting chain 2-3 is connected to the clamp chain connecting plate 2-7. In order to prevent external substances from affecting the lifting chain 2-3 and causing it to become stuck, the lifting chain 2-3 can be installed in a closed structure, that is, the column frame 1 is assembled from multiple assembly plates to prevent the lifting chain 2-3 from being exposed. The lifting mechanism 2 in this embodiment adopts a chain drive transmission method. Compared with the traditional belt drive, the chain drive has no elastic sliding and slipping, can maintain an accurate average transmission ratio, requires a relatively small tensioning force, and the pressure acting on the lifting drive shaft 2-2 is also small, which can reduce the friction loss of the bearing. Relatively speaking, the chain drive transmission method has a compact structure and reduces space occupation. And since the sprocket and chain are usually made of metal, it can be used in harsh environmental conditions such as high temperature or oil pollution, expanding the application range of the code spreader.

[0032] In order to ensure the structural strength of the connection head of the lifting chain 2-3, a clamp lifting rib plate 2-9 is added between the two chain connecting plates 2-7. The clamp lifting rib plate 2-9 is vertically arranged between the chain connecting plate 2-7, that is, one chain connecting plate 2-7 can be connected to one end of the lifting chain 2-3, and the other chain connecting plate 2-7 can be connected to the other end of the lifting chain 2-3, and then the two chain connecting plates 2-7 are connected by two or more clamp lifting rib plates 2-9 to ensure the structural strength of the connection head of the lifting chain 2-3.

[0033] The fork mechanism 3 can move up and down under the drive of the lifting mechanism 2. In order to ensure the stability of the fork mechanism 3 during the longitudinal movement, a fixed slide rail can be set on the column frame 1, and a slider can be set on the back of the fork mechanism 3 so that the slider can be slidably installed on the slide rail to ensure the stability of the fork mechanism 3 during the longitudinal movement.

[0034] In order to avoid movement interference between the fork mechanism 3 and the matching roller 5 or to avoid the fork mechanism 3 from being lifted too high, a limit groove 1-1 is opened in the above-mentioned column frame 1, and the above-mentioned clamp chain connecting plate 2-7 is located in the above-mentioned limit groove 1-1 and drives the above-mentioned fork mechanism 3 to move up and down under the drive of the above-mentioned lifting mechanism 2. Specifically, the size of the limit groove 1-1 can be set as needed, but it must be located above the matching roller 5.

[0035] The fork extension mechanism 3 in this embodiment includes a fork extension motor 3-1, a swing arm mechanism 3-2, a swing top plate 3-3, a fork plate connecting plate 3-4, a clamp fork plate 3-5, a clamp arm connecting plate 3-6 and a slider connecting plate 3-7. The above-mentioned swing arm mechanism 3-2 is installed at the output end of the above-mentioned fork extension motor 3-1, the above-mentioned swing top plate 3-3 is connected between the above-mentioned swing arm mechanism 3-2 and the above-mentioned fork plate connecting plate 3-4, the above-mentioned clamp fork plate 3-5 is installed on the above-mentioned fork plate connecting plate 3-4, the above-mentioned fork plate connecting plate 3-4 is slidably connected to the above-mentioned clamp arm connecting plate 3-6, the above-mentioned clamp arm connecting plate 3-6 is connected to the above-mentioned slider connecting plate 3-7, and the above-mentioned slider connecting plate 3-7 is connected to the above-mentioned clamp chain connecting plate 2-7. Specifically, the swing arm mechanism 3-2 includes a clamp-driven multi-V belt pulley, a swing multi-V belt pulley, a multi-V belt, a transmission gear shaft and a swing arm connecting plate. The clamp-driven multi-V belt pulley is installed at the output end of the fork extension motor 3-1, and the transmission gear shaft is passed through the swing multi-V belt pulley and the swing arm connecting plate, and the swing arm connecting plate is arranged on the side of the swing multi-V belt pulley. The clamp-driven multi-V belt pulley and the swing multi-V belt pulley are connected and transmitted by a multi-V belt. The swing top plate 3-3 is provided with a longitudinal slide groove. Under the action of the fork extension motor 3-1, the swing arm connecting plate can slide up and down in the slide groove on the swing top plate 3-3, thereby driving the fork plate connecting plate 3-4 to move forward and backward, that is, driving the clamp fork plate 3-5 to move forward and backward to realize the stacking and stacking of the turnover box 6.

[0036] In order to ensure the performance of the code separator, the two fork extension mechanisms 3 are symmetrically arranged along the central axis of the matching roller 5, and each of the fork extension mechanisms 3 has two clamp fork plates 3-5, and the two clamp fork plates 3-5 are symmetrically arranged along the central axis of the fork plate connecting plate 3-4, that is, multiple points act on the turnover box 6 to ensure the stability of the turnover box 6 during the stacking and palletizing process.

[0037] Furthermore, in order to ensure that the clamp fork plate 3-5 in the fork extension mechanism 3 is more stable during operation, a fork extension guide mechanism is provided between the clamp arm connecting plate 3-6 and the clamp fork plate 3-5, and the fork extension guide mechanism includes a fork extension rail 3-8 and a fork extension slider 3-9. The fork extension rail 3-8 is fixedly connected to the clamp arm connecting plate 3-6, and the fork extension slider 3-9 is fixedly arranged on the top of the clamp fork plate 3-5. The fork extension slider 3-9 is slidably installed on the fork extension rail 3-8.

[0038] To prevent the clamp fork plate 3-5 from directly contacting the turnover box 6 and reduce wear on the turnover box 6 and the clamp fork plate 3-5, a detachable fork plate pad 3-10 is provided at the end of the clamp fork plate 3-5. Specifically, the fork plate pad 3-10 can be fixedly connected by bolts or other means to facilitate replacement of the fork plate pad 3-10. The fork plate pad 3-10 is made of nylon material with high mechanical strength and good toughness.

[0039] The specific usage method of the turnover box code separator in this embodiment is as follows: when the turnover box 6 is stacked into the axial guide guardrail assembly and into the code separator, the guide guardrail plate 4-1 of the axial guide guardrail assembly limits the turnover box 6 to the left and right. After the limit, the center line of the turnover box 6 deviates from the center line of the matching roller 5 by ±2mm. The matching roller 5 has a front end block. When the turnover box 6 is conveyed to the front end block for limit, the center of the turnover box 6 coincides with the center of the code separator, and the fork mechanisms 3 on both sides simultaneously run inward to the specified position, the lifting mechanism 2 runs, and the fork mechanism 3 rises to drive the turnover box 6 to rise until the lifted turnover box 6 rises to a position of the height of one turnover box 6, the front end block position drops, and the bottom turnover box 6 is conveyed out of the code separator or the next turnover box 6 flows into the code separator, and the lifting mechanism 2 drives the fork mechanism 3 to drop to complete the stacking or separation of the turnover box 6.

[0040] The turnover box code separator in this embodiment has an ingenious structure. By arranging an end blocking mechanism 4 that can be used in conjunction with the fork mechanism 3 on the side of the roller conveyor 5, the turnover box 6 can be moved in the right direction while the upper and lower turnover boxes 6 can be quickly separated. This solves the technical problem in the prior art that the turnover boxes 6 are easily sucked together and difficult to separate when stacked. It reduces the labor intensity of the operators and the labor cost, increases the market competitiveness of the enterprise, and is conducive to the promotion and application of the above-mentioned turnover box code separator in the market.
