Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of door frame production and relates to an unmanned stacking assembly for door outer linear frames. BACKGROUND

[0002] A door outer linear frame is a rectangular ring-shaped door frame formed by four frame strips being connected at right angles. The door frame needs to be built with a door panel to form the entire door body. In a production line, the door frame and the door panel are usually produced in separate workshops, or there are manufacturers specializing in door frames or door panels.

[0003] After the door frame is processed, because of its large size, the door frame needs to be temporarily stacked and stored after being formed. In the prior art, the door frame is usually manually stacked after being produced, and the degree of automation is not high, which needs to be improved. SUMMARY

[0004] The application aims to solve the problem of low automation degree of the stacking mode of the existing door frame assembly and provides an unmanned stacking assembly for door outer linear frames.

[0005] The application can be realized by the following technical scheme. An unmanned stacking assembly for door outer linear frames comprises a chassis, two groups of conveying belts arranged parallel to each other on the chassis, and a stacking assembly arranged at the tail end of the conveying belts and used for stacking the door frames from top to bottom. The conveying belt comprises a conveying support fixed to the chassis. The stacking assembly comprises two groups of stacking conveying devices arranged around the conveying supports of the two groups of conveying belts. The stacking conveying device comprises two groups of supporting vertical rods arranged on the conveying supports, a supporting block slidingly arranged on the supporting vertical rods, a supporting driving component arranged between the supporting block and the supporting vertical rods, a supporting plate telescopically arranged in the horizontal direction of the supporting block, a supporting cylinder fixed to the supporting block and used for driving the supporting plate to perform telescopic movement, and a smooth upper surface of the supporting plate, which is not blocked by the edge of the door frame during the lifting movement in the retracted state and can contact the edge of the door frame in the extended state.

[0006] In the above-mentioned unmanned stacking assembly for door outer linear frames, the tail end of the conveying belt is also provided with an auxiliary supporting assembly used for supporting the door frame, and the auxiliary supporting assembly comprises two groups of auxiliary supporting devices arranged around the conveying supports of the two groups of conveying belts. The auxiliary support device includes two sets of auxiliary support uprights mounted on the conveying bracket. Auxiliary support blocks are slidably mounted on the auxiliary support uprights. An auxiliary support drive component is provided between the auxiliary support blocks and the auxiliary support uprights. An auxiliary support plate is retractably mounted on the auxiliary support blocks in the horizontal direction. An auxiliary support cylinder is fixed on the auxiliary support blocks to drive the auxiliary support plate to perform retractive movement. The auxiliary support plate will not be blocked by the edge of the door frame when it is retracted, and it can contact the inside edge of the door frame when it is extended. The outer bottom surface of the support plate has a smooth right angle, forming a smooth inclined surface at the outer bottom.

[0007] In the above-mentioned unmanned stacking yard assembly of the door frame, the side of the conveying bracket is provided with a horizontal slide rail parallel to the direction of the conveying device. Two sets of sliders are slidably arranged on the horizontal slide rail. The two sets of uprights on the stacking conveying device are respectively fixed on the two sets of sliders. The sliders and the slide rail are directly provided with a horizontal driving component that makes the sliders move on the slide rail.

[0008] In the above-mentioned unmanned storage yard assembly with an external frame, the conveyor belt includes two sets of drive wheels rotatably disposed at the front and rear ends of the conveyor support, a conveyor belt tightly sleeved on the two sets of drive wheels, and a conveyor drive component fixed relative to the conveyor support for driving the drive wheels to rotate.

[0009] Compared with existing technologies, the unmanned stacking assembly of the door frame can achieve highly efficient automated stacking in the stacking process after door frame production, reducing manpower and improving the production efficiency of energy-saving doors and windows.

[0011] The technical methods are already very mature, and this invention will not provide any special explanation.

[0012] The support block 5, which is supported by the drive component, moves back and forth linearly on the support column 4. Therefore, a conventional linear drive structure can be used, such as a gear and rack, a lead screw, or a cylinder.

[0013] This equipment is compatible with the dimensions of door frame products. Specifically, the two side edges of the door frame should extend beyond the ends of the two side conveyor belts 2, so that the support plate 6 can lift the entire door frame from these side edges.

[0014] The operation process is as follows: The door frame is fed in from one end of the conveyor and stops when it reaches the stacking assembly. Then, the stacking conveyor operates. When the support plate 6 approaches the door frame, it retracts to prevent it from being blocked by the door frame below. Then, the support plate 6, along with the support block 5, descends to the bottom of the door frame. Next, the support plate 6 extends, at which point the outer end of the support plate 6 is at the bottom of the side frame of the door frame. That is, from the projection view, the outer end of the support plate 6 overlaps with the side frame of the door frame. After the support plate 6 rises along with the support block 5, it supports the side frame of the door frame to lift the entire door frame, thus completing the lifting of the first door frame. When it is necessary to lift the next new door frame, the above operation is repeated. However, when the support plate 6 approaches the door frame and then retracts, the door frame that was originally supported by the support plate 6 will fall onto the door frame waiting to be lifted below, realizing the situation of multiple door frames stacked together. In this case, the support plate 6 lifts the door frame along with the new door frame in addition to the original number of door frames. When a sufficient number of door frames have been stacked for the target period through multiple operations, the stacked door frames can be removed with the assistance of a forklift or robotic arm.

[0015] The above method can achieve the stacking function of door frames, but there are still some serious problems. The door frame itself has high strength requirements and cannot be made of lightweight materials. Therefore, the metal composite steel material of the door frame itself will also make the door frame heavy. So when many door frames are stacked together, the structural strength requirements of the support plate 6 are very high to support these door frames. Therefore, it is difficult to use thin plates for the support plate 6. The bending resistance of thin plates is absolutely insufficient under the working requirements of this invention. The support plate 6 itself needs to be a thick plate with a wide thickness. However, precisely because the thick plate also has a certain thickness, even if the support plate 6 retracts at the position closest to the bottom of the door frame to be supported, the height gap between the upper and lower door frames will still be at least the thickness of the support plate 6. After the support plate 6 retracts, one or more stacked door frames above will fall simultaneously. Because the support plate 6 is thick, the falling distance is also large. When too many door frames are stacked, the stacked door frames are very heavy, so when they fall and hit the lower door frame, they will generate a large impact force, which will produce two adverse risks: first, the impact process will deform the door frames between each other; second, the momentum generated will create a vibration effect, making it impossible for the upper and lower door frames to be completely aligned vertically after the vibration.

[0016] Therefore, the present invention provides the following optimization scheme to solve the above problems: The tail end of the conveyor belt 2 is also provided with an auxiliary support assembly for lifting the door frame. The auxiliary support assembly includes two sets of auxiliary support devices respectively set around the conveyor supports 3 of the two sets of conveyor belts 2. The auxiliary support device includes two sets of auxiliary support uprights 9 set on the conveying bracket 3. Auxiliary support blocks 10 are slidably and vertically arranged on the auxiliary support uprights 9. An auxiliary support driving component is provided between the auxiliary support blocks 10 and the auxiliary support uprights 9. An auxiliary support plate 11 is retractably provided in the horizontal direction of the auxiliary support blocks 10. An auxiliary support cylinder 12 for driving the auxiliary support plate 11 to perform retractive and telescopic movements is fixed on the auxiliary support blocks 10. The auxiliary support plate 11 will not be blocked by the edge of the door frame when it is retracted. The auxiliary support plate 11 can contact the inside edge of the door frame when it is extended. The outer bottom surface of the support plate 6 has a smooth right angle, so that the outer bottom surface forms a smooth inclined surface 8.

[0017] The above preferred solutions are used to solve the problem of door frame stacking falling directly from the support plate 6 onto the new door frame below, causing an impact.

[0018] The preferred solution works as follows: The conveyor belt 2 transports the door frames to be stacked to a stop located below the stacking assembly and the auxiliary support assembly. The door frame to be stacked is named the new door frame. The empty support plate 6 or the support plate 6 with several door frames already stacked descends to a position higher than the new door frame. Then, the support cylinder 7 releases the force so that there is no internal force between the support plate 6 and the support block 5 in the piston direction of the support cylinder 7 (that is, after an external force is applied in the piston direction, the support plate 6 will extend and retract relative to the support block 5). Then, the auxiliary support plate 11 rises and contacts the new door frame, lifting the new door frame. After the auxiliary support plate 11 continues to rise, the new door frame will lift the stack of door frames on the support plate 6 from bottom to top to complete the stacking function. During this process, the new door frame rises from the smooth inclined surface 8 of the support plate 6. Because the support cylinder 7 releases the force, the support plate 6 will automatically move away from the edge as the new door frame gradually rises below. When the new door frame contacts the stack of door frames originally being dragged on the support plate 6, the support plate 6 will completely move away.

[0019] Therefore, the stacked door frames do not fall directly onto the new door frame. Instead, they only come into contact with the new door frame below at the very last moment after the smooth inclined surface 8 of the support plate 6 is gradually removed. This solves the two adverse risks mentioned above.

[0020] Then the support plate 6 moves down to a height lower than the auxiliary support plate 11, the support cylinder 7 is activated again to extend the support plate 6, and then the support plate 6 lifts up the new door frame on the auxiliary support plate 11 and the original door frame together, completing the stacking function.

[0021] The conveying support 3 is provided with a horizontal slide rail 13 parallel to the direction of the conveying device on each side. Two sets of sliders are slidably mounted on the horizontal slide rail 13. The two sets of uprights on the stacking conveying device are respectively fixed on the two sets of sliders. The sliders and the slide rail are directly provided with a horizontal driving component that makes the sliders move on the slide rail.

[0022] The horizontal drive component can be a motor built into the slider, and a rack is fixed on the slide rail. A gear is sleeved on the output end of the motor. After the gear meshes with the rack, the operation of the motor can drive the slider to move on the slide rail.

[0023] The conveyor belt 2 includes two sets of drive wheels rotatably mounted at the front and rear ends of the conveyor support 3, a conveyor belt tautly fitted onto the two sets of drive wheels, and a conveying drive component fixed relative to the conveyor support 3 for driving the drive wheels. The conveying drive component may be a motor.
