Technical Field

The utility model relates to the technical field of piston handling equipment, in particular to a piston boxing device and a piston blanking system.

Background

In order to improve the service performance of the piston, a coating is prepared on the surface of the piston. The coating can be stably and reliably attached to the surface of the piston only after being modified and solidified by high-temperature sintering treatment, so that the effect of improving the surface characteristics of the piston is achieved.

When the piston is discharged from the high-temperature sintering furnace, the piston needs to be transferred from the furnace mouth to a material frame for conveying for the next process. Because the temperature of the piston which is discharged from the furnace is higher, the environment is too bad, the manual boxing operation is not recommended to be adopted at the furnace mouth, and an automatic boxing device for discharging and boxing the piston is required to be designed.

In the prior art, automatic transformation of a piston blanking line of a sintering furnace by an automatic means such as a blanking robot can be considered. Considering that when the sintering furnace operates, a large number of pistons are simultaneously put into the furnace for simultaneous sintering. Therefore, the piston is also fed in batch at the same time. When the automatic transformation is performed, the function of releasing operators from the severe environment is realized in an unattended manner within a certain time, and the overall operation efficiency of automatic blanking is considered to be improved so as to match the blanking speed of the batch blanking of the sintering furnace.

Detailed Description

The present utility model will be described in detail below with reference to the drawings and the specific embodiments, and in the present specification, the dimensional proportion of the drawings does not represent the actual dimensional proportion, but only represents the relative positional relationship and connection relationship between the components, and the components with the same names or the same reference numerals represent similar or identical structures, and are limited to the schematic purposes.

Fig. 1 is an overall schematic diagram of the piston blanking system of the present utility model. The pistons W2 are output in batches from the conveyor belt at the outlet of the firing furnace W1 and stacked at the outlet to wait for blanking. The piston blanking system is arranged at the outlet of the sintering furnace W1 and is used for conveying pistons W2 accumulated at the outlet of the sintering furnace W1 into a material frame. The piston W2 which is orderly accommodated by the material frame is conveyed to a transfer bin for standby or directly sent to the next process for treatment. In order to realize the unattended operation of the piston W2, the piston blanking system 1 comprises at least one transfer robot 3 for picking and placing the piston W2 and a piston boxing device 2 arranged in the working range of the transfer robot 3, wherein the working range of the transfer robot 3 simultaneously covers a discharge hole of the firing furnace W1. The robot arm end of the transfer robot 3 is provided with an actuator 31 for picking and placing the piston W2, and the actuator may be a gripper capable of controlled opening and closing, and the gripper is used to grasp and transfer the piston W2. In order to accurately position the piston W2 when picking and placing the workpiece, the clamping jaw is ensured to accurately finish the grabbing operation and the releasing operation at the set positions. The tail end of the mechanical arm of the carrying robot 3 is optionally provided with a visual recognition device, and the control and adjustment of the position of the executing piece 31 are realized through the accurate position of the piston W2 fed back by the visual recognition device. The piston packing device 2 is preferably disposed immediately in front of the discharging direction of the firing furnace W1. At this time, the transfer robot 3 is located between the firing furnace W1 and the piston packing device 2, and the operation range of the transfer robot 3 covers the discharge port of the firing furnace W1 and the piston packing device 2 on both sides thereof. If the piston packing device 2 is disposed on both sides of the discharge port of the firing furnace W1, the working range of the robot arm end of the transfer robot 3 may not completely cover the discharge port of the firing furnace W1 and the piston packing device 2 if it is disposed between the firing furnace W1 and the piston packing device 2.

Still referring to fig. 1, in a normal mounting orientation, the piston boxing apparatus 2 includes two sets of frame positioning members 21 and a set of frame transfer members 22. The frame positioning assembly 21 includes a set of frame brackets 211 that can be controlled to rise and fall in a vertical direction. The two sets of frame positioning assemblies 21 are arranged side by side, where the side by side arrangement means that the moving directions of the frame brackets 211 of the two sets of frame positioning assemblies 21 are all along the vertical direction, and the positions of the frames W3 on the two sets of frame positioning assemblies 21 are the same. The two groups of material frame positioning components 21 are respectively used for empty box feeding and piston discharging. The frame movement module 221 of the frame transfer unit 22 is movable in a horizontal plane through the two sets of frame positioning units 21. The frame transfer assembly 22 is capable of gripping the take out frame W3 to translate it from one set of frame positioning assemblies 21 to another set of frame positioning assemblies 21 for release. At the bottom of the frame carrier 211, a frame transport assembly 23 is optionally provided to effect movement of an empty frame W3 into the frame carrier 211 or movement of a frame W3 filled with pistons W2 out of the frame carrier 211.

The following is a working flow of the piston packing device 2. The two frame positioning assemblies 21 are functionally separated into an empty box lifting assembly 21A and a full box lowering assembly 21B, respectively. The material frames W3 are circulated in batches with a certain stacking layer number (such as 8 layers in actual use). First, the material frames W3 stacked by a certain number of layers are fed from the material frame conveying assembly 23 below the empty box lifting assembly 21A onto the material frame brackets 211 of the empty box lifting assembly 21A. Since the frame bracket 211 can be lifted under control, the lifting operation of the frame bracket 211 always makes it possible to always keep the topmost layer of the empty boxes on the frame bracket 211 at a specific position. In this particular position, the frame transfer assembly 22 may clamp the take out frame W3 such that the frame W3 moves with the frame transfer assembly 22 to the full bin lowering assembly 21B. Also, since the frame support 211 of the full-tank lowering assembly 21B is also controlled to be raised and lowered, the full-tank lowering assembly 21B always leaves a layer of empty frame W3 for the empty frame transfer assembly 22 on top of the full-tank lowering assembly 21B when the frame transfer assembly 22 feeds the frame W3. The above operation completes the entering of the empty box. After the empty box is put in place, the top layer of the full box descending assembly 21B is the empty box, the carrying robot 3 sequentially takes out the pistons W2 from the discharge holes of the sintering furnace W1, and the full material frames W3 are arranged in a certain arrangement sequence in the material frames W3. At this time, the piston packing device 2 repeats the above empty box loading operation. When the number of stacked layers of the material frames W3 on the full tank descent assembly 21B reaches a maximum, the material frames W3 filled with the pistons W2 are sent out in a stacked manner from the material frame conveyance assembly 23 below the full tank descent assembly 21B. And (3) completing a complete boxing cycle, and repeating the steps in the next cycle to realize the entering of empty box stacks and the output of full box stacks. In this process, only manual intervention is required at the beginning or end of a cycle, to feed the empty stacked bins and to transfer the full stacked bins away from the exit of the frame transfer assembly 23. Therefore, the normal operation under the long-time unattended operation can be realized. Because the material frames W3 are fed in batches in a stacking mode, the frequency is not required to wait for switching the material frames W3 in the operation process of taking and placing the pistons W2 by the conveying robot 3, so that the overall conveying efficiency of the system is improved, the discharging speed of the system even exceeds that of the firing furnace W1, and the pistons W2 are prevented from continuously accumulating at the discharging holes of the firing furnace W1.

Fig. 2 is a schematic structural view of the frame positioning assembly 21. The material frame positioning assembly 21 comprises a material frame bracket 211 which is arranged in a moving manner along the vertical direction, wherein the material frame bracket 211 is provided with two groups of material frame supporting plates 212, the two groups of material frame supporting plates 212 are arranged in the same horizontal plane in parallel, one end of each material frame supporting plate 212 is fixed on the material frame bracket 211, and one end of each material frame supporting plate is open. The material frame bracket 211 is arranged on two groups of lifting guide rails 213 which are arranged in parallel along the vertical direction, and is driven to lift by a conveying chain fixed on the material frame bracket 211, the conveying chain respectively bypasses chain wheels 214 arranged at two ends of the lifting guide rails 213, and one chain wheel is driven by power, so that the conveying chain drives the material frame bracket 211 to lift. Typically this power is provided by a lift servo motor 215 coaxially coupled to the sprocket 214.

Fig. 3 is a schematic view of the frame transfer assembly 22. The frame transfer assembly 22 includes a frame moving module 221 capable of translating in a horizontal plane, the frame moving module 221 includes two horizontally opposed frame clamping plates 222, and the frame clamping plates 222 can be stretched and contracted under the driving of respective frame supporting members 223, so that the frame is clamped between the frame clamping plates 222 when stretched out, and the frame is prevented from falling. Optionally, the lower edge of the material frame clamping plate 222 is provided with a material frame supporting member 223 protruding towards one side surface, and the material frame supporting member is located at the bottom surface of the material frame when the material frame W3 is clamped between the material frame clamping plates 222, so that the bottom surface of the material frame can be limited, and the material frame is prevented from sliding down. In order to realize the horizontal translation of the material frame moving module 221, the material frame moving module 221 is arranged on a horizontal movement module 224 arranged in the horizontal direction, and the horizontal movement module 224 commonly uses a servo electric cylinder to realize the guiding and driving. In order to avoid that the moving process affects the empty or full stacking boxes when switching between the operations of taking and placing the material frames W3 and moving the material frames W3, the material frames W3 are usually required to be lifted appropriately, so the horizontal movement module 224 is further provided with a vertical movement module 225, and the material frame movement module 221 is disposed on the vertical movement module 225. In order to solve the above-mentioned problems, it is also possible to control the up-and-down movement of the frame bracket 211, so that the vertical movement module 225 is not necessary.

Returning to fig. 1, the material frames W3 are fed into the empty boxes in a stacked manner on the empty box lifting assemblies 21A, respectively, while the piston filling of the material frames W3 is completed continuously on the topmost layer on the full box lowering assemblies 21B. In order to prevent the stacked material frames W3 from being inclined and collapsed during operation, the piston boxing apparatus 2 is further provided with vertical limiting frames 216 along the sides of the material frames W3, the limiting frames being provided on three sides of the material frame positioning assembly 21 and extending in the vertical direction, and the material frames W3 are lifted in the space defined by the limiting frames 216 when the material frame bracket 211 is lifted. One side is open, and the feeding frame W3 is used.

The frame conveying assembly 23 is typically a conveyor consisting of a number of conveying rollers disposed below the frame carrier 211. In order to smoothly complete the transition of the material frame W3 between the material frame bracket 211 and the material frame conveying assembly 23, the avoiding groove 231 for avoiding the material frame bracket 211 is formed in the conveying roller below the material frame bracket 211. When the material frame bracket 211 is positioned at the bottom end, the material frame bracket 211 enters the avoiding groove 231, the upper surface of the material frame bracket 211 is lower than the bearing surface of the conveying roller, the material frame W3 can be smoothly conveyed into the upper part of the material frame bracket 211 by the conveying roller, and when the material frame bracket 211 ascends, the material frame W3 is placed on the material frame bracket 211 to finish transferring.

The foregoing is merely illustrative of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and various modifications and improvements made by those skilled in the art to which the utility model pertains will fall within the scope of the utility model as defined by the appended claims without departing from the spirit of the utility model.
