Description

Technical Field

[0001] The present application relates to the field of workpiece transportation, and in particular to a material vehicle device for transporting shaft products. Background Art

[0002] The production of shaft products requires multiple processing steps. However, due to the large size of the processing equipment and the long distances between processing stations of different processes, shaft products need to be promptly transported to the next processing station for subsequent processing after one processing step.

[0003] For example, the invention patent with patent announcement number CN114750814A discloses a material cart device for shaft products, including: a material loading cart, a material lifting mechanism and a positioning mechanism; the material loading cart includes a vehicle bottom plate, a left side plate, a right side plate, a front side plate and a rear side plate, and the upper end surface of the vehicle bottom plate is provided with a material placing pad; the material lifting mechanism includes a bracket, a horizontal slide rail is connected to the bracket, an automatic slide rail is provided on the horizontal slide rail, a sliding sleeve is provided at the outer end of the automatic slide, a guide rod is installed in the sliding sleeve, and a lifting plate, a grabbing plate and a magnet assembly are provided at the lower end of the guide rod; the positioning mechanism includes a clamping wrench and a positioning arm connected to the left and right ends of the bottom of the bracket, the positioning arm is provided with a positioning slot, the left end of the material loading cart is provided with a clamping slot plate adapted to the clamping wrench, and the right end of the material loading cart is provided with a positioning protrusion adapted to the positioning slot of the positioning arm.

[0004] When using the above-mentioned material cart device for shaft products, the number of shaft products that can be transported at a single time is limited. If the distance between the processing stations of two processes is far, after all products are processed in the next processing process, the material loading cart may not yet arrive at the material lifting mechanism to provide products for processing, resulting in a processing blank period between the time when all products are processed in the next processing process and the time when the material loading cart arrives at the material lifting mechanism. That is, during this period of time, no products are being processed at the next processing process, which is not conducive to improving the processing efficiency of the products and needs to be improved. Summary of the invention

[0005] In order to improve the processing efficiency of shaft products, the present application provides a material cart device for transporting shaft products.

[0006] The present application provides a material vehicle device for transporting shaft products, which adopts the following technical solution:

[0007] A material vehicle device for transporting shaft products, comprising a material loading vehicle and a material lifting mechanism, wherein the material loading vehicle is provided with universal wheels, the material loading vehicle is provided with a receiving slot, a through hole is provided on the outer side wall of the material loading vehicle, the through hole is communicated with the receiving slot, a plurality of carrier plates are slidably connected in the receiving slot, the plurality of carrier plates are vertically distributed, and the carrier plates slide close to or away from the through hole, a plurality of storage slots are provided on each of the carrier plates, and the material lifting mechanism is used to grab the products in the storage slots;

[0008] The material loading vehicle is provided with a lifting and sliding limit plate, the limit plate extends into the through hole and abuts against the carrier plate in the accommodating groove, a through hole is opened on the carrier plate, the through hole is located at one end of the carrier plate away from the through hole, the limit plate is passed through the through hole, and a positioning component for positioning is provided on the limit plate.

[0009] By adopting the above technical solution, the products to be transported are placed in the storage slots on several loading plates, and the total number of products placed on the material loading vehicle can be determined according to the actual situation, that is, the distance between the production equipment of two processing steps in the actual production scenario, so that the total processing time of all the products transported by the material loading vehicle at one time meets the time required for the material loading vehicle to transport the products to the material lifting mechanism at the processing step next time, thereby realizing continuous processing of the next step, reducing the occurrence of processing blank periods, making full use of time, and thus improving product processing efficiency.

[0010] When transporting products, the limiting plate abuts against several carrier plates in the accommodating groove, thereby limiting the carrier plates and preventing the carrier plates from slipping out of the accommodating groove during the movement of the material loading vehicle. When processing products, after the material lifting mechanism has taken out the products on the uppermost carrier plate in the accommodating groove, the positioning state of the limiting plate is released, the limiting plate is moved up to disengage from the through hole, and the carrier plate from which the products have been taken is moved close to the through hole, so that the carrier plate passes through the through hole and the through hole on the carrier plate is aligned with the limiting plate, and then the limiting plate is moved downward, so that the limiting plate passes through the through hole on the above-mentioned carrier plate and positions the limiting plate, and the positioning of the above-mentioned carrier plate is achieved by the limiting plate abutting against the inner wall of the through hole, so that the material lifting mechanism can grab the products on the carrier plate below.

[0011] Optionally, the positioning assembly includes a fixed block provided on the material loading vehicle, a plurality of sliders slidably connected to the limit plate and an elastic member provided on the limit plate, the plurality of sliders are distributed along the sliding direction of the limit plate, the sliders slide close to or away from the fixed block, a positioning hole is provided on the slider, the positioning hole is for the fixed block to pass through, the elastic member presses against the slider so that the slider tends to move away from the fixed block.

[0012] By adopting the above technical solution, when the limit plate needs to be moved, the limit plate is moved up to make the fixed block disengage from the perforation. At this time, the slider moves away from the fixed block under the action of the elastic member 1, so that the fixed block and the perforation are staggered, and the limit plate can be moved.

[0013] When the limit plate is about to move to the specified position, move the slider located above the fixed block and closest to the fixed block so that the perforation on the slider is aligned with the fixed block, and continue to move the limit plate so that the limit plate moves to the specified position and the fixed block is penetrated by the perforation, so that the limit plate can be positioned. The limit plate can be positioned by moving the slider, which makes positioning the limit plate more convenient.

[0014] Optionally, a plurality of slide grooves are provided on the inner side wall of the accommodating groove, the plurality of slide grooves are distributed vertically, and the slide grooves penetrate the material loading vehicle in a direction close to the through hole, and the carrier plate is inserted into the slide grooves.

[0015] By adopting the above technical solution, the storage plate can be inserted into the corresponding slide groove according to the height of the product, so that the distance between adjacent loading plates is adapted to the height of the product to be transported, thereby being able to transport shaft products of different heights, thereby improving the applicability of the material cart device.

[0016] Optionally, the material loading cart is slidably connected with a plurality of limit columns, the limit columns correspond to the slide slots, and the limit columns slide into or out of the corresponding slide slots. The material loading cart is provided with an inclined rod, the inclined rod corresponds to the limit columns, the inclined rod is inclined toward the direction approaching the corresponding slide slot and approaches the through hole, and the inclined rod passes through the limit columns, and the limit columns are slidably connected to the inclined rod. The material loading cart is also provided with an elastic member 2, the elastic member 2 presses against the limit column so that the limit column has a tendency to approach the through hole, and a slot is provided on the loading plate, and the slot is for the limit column to be inserted into.

[0017] By adopting the above technical scheme, when the carrier plate is inserted into the slide slot, the carrier plate abuts the limit column to push the limit column to move away from the through hole, and the limit column moves away from the corresponding slide slot along the inclination direction of the inclined rod until the limit column and the carrier plate are offset, and the carrier plate continues to move and is inserted into the slide slot until the slot and the limit column are aligned. Under the action of the second elastic member, the limit column moves close to the through hole and is inserted into the slot. When the carrier plate from which the product has been taken is moved out of the through hole, the carrier plate is limited by the limit column abutting the inner wall of the slot to prevent the carrier plate from slipping out of the accommodating slot, so as to facilitate the alignment of the through hole and the limit plate. When the position of the carrier plate needs to be replaced, the limit column is moved away from the through hole to make the limit plate and the carrier plate offset, and the carrier plate can be taken out of the slide slot.

[0018] Optionally, the fixed block is located on a side of the limiting plate away from the receiving slot, the sliding block is provided with an inclined surface, the inclined surface is located on a side of the limiting plate close to the receiving slot, the inclined surface is inclined downward in a direction away from the receiving slot, and the inclined surface is used to press against the loading plate.

[0019] By adopting the above technical solution, when transporting products, the inclined surface presses the loading plate against the inner wall of the lower end of the slide slot under the action of the elastic member 2. When the material loading vehicle shakes due to uneven ground during movement, the loading plate is cushioned, thereby reducing the situation where the loading plate shakes with the material loading vehicle or collides with the material loading vehicle due to shaking, reducing the situation where the product leaves the storage slot, and reducing the generation of noise, thereby reducing the interference with the work of surrounding staff.

[0020] Optionally, a limiting groove is provided on the fixing block, the limiting groove is located on a side of the fixing block away from the accommodating groove, and the sliding block is inserted into the limiting groove.

[0021] By adopting the above technical solution, a limit groove is set. When the fixed block penetrates the positioning hole, the slider is inserted into the limit groove under the action of the elastic member 1, and the slider is abutted against the inner wall of the limit groove, thereby reducing the situation where the limit plate moves due to sudden factors when there is no need to move the limit plate, causing the fixed block and the perforation to separate, thereby improving the positioning stability of the limit plate on the material loading vehicle.

[0022] Optionally, an elastic sheet is provided on the material loading vehicle, and the elastic sheet is located on the side of the through hole away from the limiting plate. A positioning hook is provided on the elastic sheet, and the slider includes a sliding part slidably connected to the limiting plate and a rotating part rotatably connected to the sliding part. The positioning hole is provided on the rotating part, and the positioning hook is inserted into the positioning hole.

[0023] By adopting the above technical solution, when transporting products, the rotating part is rotated so that the positioning hole faces the positioning hook, and then the positioning hook on the elastic sheet is inserted into the positioning hole, thereby opening the elastic sheet, and the gap between the limit plate and the inner wall of the through hole is covered by the elastic sheet. When a product leaves the storage slot and rolls in the receiving slot as the material loading vehicle moves, the elastic sheet abuts against the product, thereby preventing the product from falling from the material loading vehicle and being damaged, so that subsequent staff can put the product back into the storage slot.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. Place the products to be transported in the storage slots on several carriers. The total number of products placed on the material loading vehicle can be determined according to the actual situation, that is, the distance between the production equipment of two processing steps in the actual production scenario, so that the total processing time of all products transported by the material loading vehicle at one time meets the time required for the material loading vehicle to transport the products to the material lifting mechanism at the processing step next time, thereby realizing continuous processing of the next step, reducing the occurrence of processing blank periods, making full use of time, and improving product processing efficiency;

[0026] 2. When the carrier plate is inserted into the slide slot, the carrier plate abuts against the limiting column to push the limiting column to move away from the through hole and the corresponding slide slot until the limiting column and the carrier plate are staggered, and the carrier plate continues to move and insert into the slide slot until the slot and the limiting column are aligned. The limiting column is inserted into the slot under the action of the second elastic member. When the carrier plate after the product is taken out is moved out of the through hole, the limiting column abuts against the inner wall of the slot to limit the carrier plate, preventing the carrier plate from slipping out of the receiving slot, so as to facilitate the alignment of the perforation and the limiting plate;

[0027] 3. When transporting products, rotate the rotating part so that the positioning hole faces the positioning hook, and then insert the positioning hook on the elastic sheet into the positioning hole, thereby opening the elastic sheet, and covering the gap between the limiting plate and the inner wall of the through hole through the elastic sheet. When a product leaves the storage slot and rolls in the receiving slot as the material loading vehicle moves, the elastic sheet abuts against the product, thereby preventing the product from falling from the material loading vehicle and being damaged.

[0053] The implementation principle of a material vehicle device for transporting shaft products in the embodiment of the present application is as follows:

[0054] The products to be transported are placed in the storage slots 421 on the plates 41. The total number of products placed on the material loading vehicle 1 can be determined according to the actual situation, that is, the distance between the production equipment of two processing steps in the actual production scenario, so that the total processing time of all the products transported by the material loading vehicle 1 at one time meets the time required for the material loading vehicle 1 to transport the products to the material lifting mechanism 2 at the processing step next time, thereby realizing continuous processing of the next step, reducing the occurrence of processing blank periods, making full use of time, and improving product processing efficiency.

[0055] When transporting products, the plate body 41 is pressed against several plate bodies 41 in the receiving groove 11 through the inclined surface 8 on the sliding portion 721, thereby limiting the plate body 41 and preventing the plate body 41 from slipping out of the receiving groove 11 during the movement of the material loading vehicle 1. When the material loading vehicle 1 shakes due to uneven ground during the movement, the plate body 41 is cushioned, thereby reducing the situation where the plate body 41 shakes with the material loading vehicle 1 or collides with the material loading vehicle 1 due to shaking, reducing the situation where the product leaves the storage groove 421, and reducing the generation of noise.

[0056] When processing products, after the material lifting mechanism 2 takes out the products on the top plate 41 in the accommodating groove 11, the positioning state of the limit plate 6 is released, and the limit plate 6 is moved up to disengage from the through hole 12, and the plate 41 from which the products have been taken out is moved close to the through hole 12, so that the plate 41 passes through the through hole 12 and the through hole 411 on the plate 41 is aligned with the limit plate 6, and then the limit plate 6 is moved downward, so that the limit plate 6 passes through the through hole 411 on the above-mentioned plate 41 and positions the limit plate 6, and the positioning of the above-mentioned plate 41 is achieved by the limit plate 6 abutting against the inner wall of the through hole 411, so that the material lifting mechanism 2 can grab the products on the plate 41 located below.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
