[0002] When steel companies produce profiles such as angle steel, channel steel, and I-beam, they need to collect and stack the finished profiles in groups in the finishing area. Profile stacking devices are generally arranged at the end of the finished product process, and products are delivered to customers in a certain pattern according to the packaging specifications of commodity steel products that meet the standards and the market, so as to realize logistics activities such as material storage, handling, loading and unloading, and transportation.

[0003] Most of the existing profile stacking methods use magnetic stacking methods, which mainly use the assistance of stacking magnetic heads to adsorb and transfer the profiles, and stack the steel layers face to face or back to back with the help of other machines. However, the existing magnetic stacking method is not suitable for stainless steel profiles, because it cannot adsorb stainless steel profiles, and its adjustable magnetic translation head and flip head are completely ineffective for stainless steel profiles.

DETAILED DESCRIPTION

[0043] The embodiments of the present invention will be described in detail below in conjunction with the embodiments and examples, but those skilled in the art will understand that the following embodiments and examples are only used to illustrate the present invention and should not be considered to limit the scope of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] In a first aspect, in some embodiments, a profile stacking device is provided, including a profile conveying mechanism, a translation mechanism, a flipping mechanism, a lifting mechanism, and an output roller table;

[0045] The profile conveying mechanism is used for sorting and conveying forward profiles. The translation mechanism and the flipping mechanism are arranged at the output end of the profile conveying mechanism. The translation mechanism and the flipping mechanism are arranged in series or in parallel.

[0046] The translation mechanism is used to transport the forward profile to the lifting mechanism, and the flipping mechanism is used to flip the forward profile into a reverse profile and transport it to the lifting mechanism, and the flipping mechanism is provided with positioning blocks for positioning the forward profile and the reverse profile respectively;

[0047] The lifting mechanism is located below the translation mechanism and the flip mechanism, and is used to receive the forward profiles conveyed by the translation mechanism and / or the reverse profiles conveyed by the flip mechanism, and to stack the profiles;

[0048] The output roller is located below the lifting mechanism and is used to receive the formed profile stacks delivered by the lifting mechanism and transport them to the next process.

[0049] The profile conveying mechanism, translation mechanism, flip mechanism, lifting mechanism, and output roller in the above-mentioned profile stacking device are all non-magnetic mechanisms. Through these non-magnetic mechanisms, the stainless steel profiles can be stacked alternately with one layer opening downward and one layer opening upward, which alleviates the problem that the existing magnetic stacking device is not suitable for stainless steel profiles. In addition, the device has a wide range of applications. It is not only suitable for the stacking of symmetrical stainless steel profiles such as H-shaped steel and I-shaped steel, but also can meet the stacking of asymmetrical shapes and multiple specifications of stainless steel profiles such as angle steel and channel steel; the equipment is simple, the operating cost is low, the reliability is high, the accuracy, stability and stacking efficiency of profile stacking are improved, the requirements of bundling quality are met, and the economic benefits are significant.

[0050] The positive profile can be understood as a profile with an opening downward, and the reverse profile can be understood as a profile with an opening upward.

[0051] The translation mechanism and the turnover mechanism can be arranged in series or in parallel at the output end of the profile conveying mechanism.

[0052] The above-mentioned profile stacking device can stack profiles in multiple stacks according to a certain number of rows and layers required by customers. It can not only realize the alternating stacking of stainless steel profiles with one layer of openings facing downwards and one layer of openings facing upwards, but also can adopt the stacking with all openings facing downwards or all openings facing upwards, or adopt the alternating stacking with one layer of openings facing upwards and one layer of openings facing downwards.

[0053] Furthermore, the profile conveying mechanism includes a conveying frame, a steel dividing unit arranged on the conveying frame, a conveying chain arranged on the conveying frame, and a conveying chain transmission mechanism for driving the conveying chain to move.

[0054] The profile conveying mechanism in this embodiment adopts a profile conveying chain structure commonly used in the art, and also includes a steel separation unit commonly used in the art, through which positive profiles, i.e., profiles with openings downward, are sorted out.

[0055] In an optional embodiment, the steel separation unit is plate-shaped, driven to pop up by a driving device, and installed at the front end of the transport frame. The steel separation unit can pop up and protrude from the upper surface of the profile transport mechanism. The conveyor chain is connected to the conveyor chain transmission mechanism, and the conveyor chain transmission mechanism includes a sprocket. The conveyor chain is driven by a motor to drive the sprocket, so that the conveyor chain arranged on the transport frame moves to transport the stainless steel profile.

[0056] Furthermore, the profile conveying mechanism is provided with a detection device, through which the start and stop of the conveying chain can be controlled.

[0057] In an optional embodiment, the detection device includes a proximity switch, a processor and a controller, the proximity switch is fixed to the side wall of the conveyor chain through a switch bracket, the output end of the proximity switch is connected to the input end of the processor, the output end of the processor is connected to the controller, and the controller is electrically connected to the motor. It should be noted here that the specific structural form of the above-mentioned detection device is not limited to this, and other structural forms commonly used in the field can also be adopted, as long as the conveying position of the profile can be effectively detected and the start and stop of the conveyor chain can be controlled.

[0058] Furthermore, the translation mechanism includes a translation support seat, a chain and sprocket type rotating mechanism, a translation support platform and a finger support mechanism, one end of the chain and sprocket type rotating mechanism is connected to the translation support seat, and the other end is connected to the translation support platform, and the translation support platform is connected to the finger support mechanism.

[0059] Further, the finger supporting mechanism comprises a finger supporting recovery cylinder and a finger supporting mechanism connected to each other;

[0060] And / or, the driving device of the chain and sprocket type rotating mechanism includes at least one of an electric motor, a hydraulic motor, an oil cylinder or an air cylinder.

[0061] The translational support platform is used to place profiles, and the finger support mechanism is connected to the translational support platform. The rapid retraction of the finger support mechanism can transfer the profiles on the translational support platform to the lifting mechanism; the translational support seat is movably connected to the chain and sprocket type slewing mechanism, and the translational support seat can provide sufficient supporting force to enable the chain and sprocket type slewing mechanism to move smoothly. The transmission of the slewing mechanism is that the driving device transmits power to each translational branch slewing mechanism through a long shaft, and its driving device can be an electric motor, a hydraulic motor, an oil cylinder or an air cylinder.

[0062] By setting up a non-magnetic translation mechanism, the forward profiles can be smoothly transported from the conveyor chain to the lifting mechanism and forward stacked. It has a simple structure and is easy to operate, which is beneficial to reducing equipment costs, repair and maintenance costs, and is beneficial to reducing scratches and damages caused by collisions between profiles.

[0063] Furthermore, the flip mechanism comprises a flip support seat and a flip arm, the lower end of the flip arm is movably connected to the flip support seat, and the side of the flip arm is provided with the positioning block;

[0064] The positioning stopper is a step stopper, including a first step stopper and a second step stopper;

[0065] The driving device of the flip arm includes at least one of a motor, a hydraulic motor, a cylinder or a pneumatic cylinder.

[0066] The flip support seat and the flip arm in the flip mechanism are movably connected, and the flip support seat can provide sufficient support force to make the flip arm flip smoothly. The transmission of each flip mechanism is driven by a driving device alone, and its driving device can be a motor, a hydraulic motor, a cylinder or a cylinder. Through the setting of the non-magnetic flip mechanism, the forward profile can be flipped into a reverse profile and smoothly transported to the lifting mechanism, and reverse stacking can be performed. The structure is simple and easy to operate, which is conducive to reducing equipment costs, repair and maintenance costs, and is conducive to reducing scratches and damage caused by collisions between profiles, etc., and improving product quality.

[0067] The positioning stopper is arranged on one side surface of the flip arm, and the positioning stopper is a step stopper, including two steps, and the lower step is arranged in the direction of movement of the facing profile; the first step stopper is a lower step, which can be used for clamping and positioning the reverse profile, and the second step stopper is a higher step, which can be used for positioning the forward profile.

[0068] Furthermore, the lifting mechanism includes a lifting platform and a lifting motor, and the lifting platform is connected to the lifting motor via a long shaft.

[0069] Furthermore, an encoder for controlling the lifting height of the lifting platform is provided at the end of the long axis.

[0070] Behind the profile conveying mechanism, there is a lifting platform and a lifting motor for driving the lifting platform up and down, which is used to collect the profiles transported by the translation mechanism and the flip mechanism, and to stack the profiles. During the stacking process, it can ensure that each layer of the stack descends a certain distance. After the stacking is completed, the lifting platform moves down to the lowest position and places the stacked profiles on the output roller. The stacking lifting platform is connected to the lifting motor through a long shaft, and an encoder is installed at the end of the long shaft to accurately control the descending distance of the lifting platform, ensuring that each layer of the stack descends a certain distance.

[0071] A data line connected to an external signal processing device can be led out from the encoder, or the encoder can be connected to a PLC. It should be noted here that the encoder and its connection control relationship are both prior art.

[0072] Furthermore, it also includes an alignment baffle, which is located in the opposite direction of the output of the output roller and is used to align the profiles on the output roller.

[0073] The alignment baffle is a fixed baffle, which is used to align the stacked profiles on the output roller. By setting the alignment baffle, the neatness of the profile stacking can be further improved, and the stacking efficiency is high.

[0074] Furthermore, the output roller table is a group of single-pass roller tables driven by a reduction motor.

[0075] The output roller is a set of single-pass rollers driven by a reduction motor, which is located at the very end of the palletizing device, below the lifting platform, and is used to cooperate with the alignment baffle to perform neat palletizing and transport the formed bales to the front of the baler.

[0076] In a second aspect, in some embodiments, a profile stacking method is also provided, comprising the following steps:

[0077] (a) After being grouped, several profiles are sorted into positive profiles and transported to the output end through a profile conveying mechanism;

[0078] (b1) The forward profile is positioned by the forward profile positioning block on the flipping mechanism, and then the translation mechanism is started to transport the forward profile to the lifting mechanism through the translation mechanism;

[0079] (b2) starting the flipping mechanism, the forward profile is flipped into a reverse profile by the flipping mechanism, during the flipping process, the profile is fixed and positioned by the reverse profile positioning block on the flipping mechanism, and then the reverse profile is transported to the lifting mechanism;

[0080] (c) the lifting mechanism receives the forward profiles and / or reverse profiles delivered by the translation mechanism and / or the flipping mechanism and performs palletizing;

[0081] (d) After palletizing is completed, the lifting mechanism moves downward and places the palletized profiles on the output roller, and the formed profile stack is transported to the next process through the output roller.

[0082] In a preferred embodiment, the above-mentioned stacking method is to first sort the profiles with openings downward through a steel sorting unit, and then convey them to the tail end of the conveyor chain through a conveyor chain;

[0083] Assuming that the first group of profiles that arrive do not need to be flipped, the profiles are blocked and positioned by the second step block on the flipping arm of the flipping mechanism, and then the translation mechanism is started, the translation support hidden under the conveyor chain rises, and the profiles are lifted and moved above the stacking lifting platform; then the finger support mechanism is quickly retracted, so that the profile opening on the translation support is placed downward on the lifting platform; then the chain sprocket rotary mechanism returns to its original position along the original path and waits at the waiting position under the chain at the tail end of the conveyor chain;

[0084] Assuming that the second group of profiles that arrive are those that need to be flipped, the profiles are detected by the detection device after reaching a certain position at the tail end of the conveyor chain, and the conveyor chain stops; the flipping mechanism is started, and the flipping arm hidden under the conveyor chain at the front rises, lifting the profile and flipping it to the top of the stacking lifting platform, with the profile opening facing upward; during the flipping process, the profile is blocked and positioned by the first step block on the flipping arm of the flipping mechanism; then the profile opening on the flipping arm is buckled upward onto the lifting platform;

[0085] In this way, the profiles are alternately stacked on the lifting table to the specified height, completing the stacking of the profiles. Finally, the profiles fall onto the output roller table and are output by the roller table for bundling and packaging.

[0086] In this way, through the above stacking method, it is achieved that the stainless steel profiles are stacked alternately with one layer of openings facing downwards and another layer of openings facing upwards, thus solving the problem of stainless steel stacking; it is not only used for the stacking of completely symmetrical stainless steel profiles such as H-shaped steel and I-shaped steel, but can also meet the stacking of asymmetrical shapes and multiple specifications of stainless steel profiles such as angle steel and channel steel; it has a wide range of applications, improves the accuracy, stability and stacking efficiency of steel stacking, and meets the requirements of bundling quality.

The translation mechanism 2 and the flipping mechanism 3 are arranged in sequence or in parallel. The translation mechanism 2 is used to convey the forward profiles to the lifting mechanism 4. The flipping mechanism 3 is used to flip the forward profiles into reverse profiles and convey them to the lifting mechanism 4. The flipping mechanism 3 is provided with positioning blocks for positioning the forward profiles and the reverse profiles respectively.

[0091] The lifting mechanism 4 is located below the translation mechanism 2 and the turning mechanism 3, and is used to receive the forward profiles from the translation mechanism 2 and / or the reverse profiles from the turning mechanism 3, and to stack the profiles;

[0092] The output roller table 5 is a set of single-pass roller tables driven by a reduction motor, located below the lifting mechanism 4, and is used to receive the formed profile stacks transported by the lifting mechanism 4 and transport them to the next process;

[0093] The alignment baffle 6 is a fixed baffle, which is located in the opposite direction of the output of the output roller 5 and is used to align the profiles on the output roller 5.

[0094] Furthermore, the profile conveying mechanism 1 includes a transport frame, a steel dividing unit arranged on the transport frame, a conveying chain arranged on the transport frame, and a conveying chain transmission mechanism for driving the conveying chain to move. A detection device is arranged on the profile conveying mechanism 1, and the start and stop of the conveying chain can be controlled by the detection device. A lifting mechanism 4 is arranged behind the profile conveying mechanism 1, including a lifting platform and a lifting motor for driving the lifting platform to move up and down, and the lifting platform is connected to the lifting motor through a long shaft. An encoder for controlling the lifting height of the lifting platform is arranged at the end of the long shaft, so as to accurately control the descending distance of the lifting platform and ensure that each layer of each yard descends a certain distance.

[0095] like Figure 2 - Figure 4 As shown, the translation mechanism 2 includes a translation support seat 21, a chain sprocket type rotary mechanism 22, a translation support platform 23 and a finger support mechanism 24. One end of the chain sprocket type rotary mechanism 22 is connected to the translation support seat 21, and the other end is connected to the translation support platform 23. The translation support platform 23 is connected to the finger support mechanism 24. The finger support mechanism 24 includes a finger support recovery cylinder 241 and a finger support 242 connected to each other; the driving device of the chain sprocket type rotary mechanism 22 includes at least one of a motor, a hydraulic motor, an oil cylinder or a gas cylinder.

[0096] like Figure 5As shown, the flip mechanism 3 includes a flip support seat 31 and a flip arm 32. The lower end of the flip arm 32 is movably connected to the flip support seat 31, and a positioning block is arranged on the side of the flip arm 32; the positioning block is a step block, including a first step block 321 and a second step block 322.

[0097] like Figure 1 - Figure 5 As shown, the working principle of the profile stacking device is as follows: the profile conveying mechanism 1 is transmitted by the chain transmission mechanism, and the profile group 7 that does not need to be turned over and the profile group 8 that needs to be turned over after being sorted by the steel separation unit are alternately sent to the rear of the profile conveying mechanism 1. And the grouped stainless steel profiles are placed on the conveying chain with the opening facing downward. According to the incoming material situation, the translation mechanism 2 or the turning mechanism 3 is started respectively, and the stainless steel profile groups transported in sequence are stacked on the lifting mechanism 4, and finally a profile stack is formed.

[0098] During the stacking process, the lifting platform gradually descends, and the encoder at the end of the long axis accurately controls the descending distance to ensure that each layer of each stack descends a certain distance; after palletizing, the lifting platform moves downward to the lowest position, places the stacked profiles on the output roller 5, and starts the output roller 5 to move towards the alignment baffle 6 to make the edges of the angle steel profiles flush, and then the output roller 5 is started in the reverse direction to move the stacked angle steel stacks to the baler for bundling, and finally the bundled products are transported to the collection stand to wait for crane lifting, thus completing the stacking process of a stainless steel profile (taking angle steel profiles as an example).

[0099] Example 2

[0100] like Figure 1 - Figure 5 As shown, this embodiment provides a profile stacking method, comprising the following steps:

[0101] (a) After being grouped by the steel dividing unit, several profiles are opened downward and conveyed to the tail end of the conveyor chain through the profile conveying mechanism 1.

[0102] (b1) When the incoming material is a profile group 7 that does not need to be turned over, it is blocked and positioned by the second step stopper 322 on the turning arm 32 in the turning mechanism 3 during the movement of the incoming material; the translation mechanism 2 is started, so that the chain sprocket type rotary mechanism 22 rotates around the central axis provided on the translation support seat 21, and the translation support platform 23 hidden under the conveyor chain rises, and the profile group 7 that does not need to be turned over is lifted and moved to the top of the stacking lifting mechanism 4; then the finger support recovery cylinder 241 of the finger support mechanism 24 is quickly retracted, so that the profile opening on the translation support platform 23 is placed downward on the lifting platform; then the chain sprocket type rotary mechanism 22 returns to its original position along the original path, and waits in the waiting position under the chain at the tail end of the conveyor chain. In this embodiment, the chain sprocket type rotary mechanism 22 is a swing arm driven by a swing hydraulic cylinder or a motor, and the swing range is less than 180°.

[0103] (b2) When the incoming material is a profile group 8 that needs to be flipped, the incoming material moves to a certain position at the tail end of the profile conveying mechanism 1 and is detected by the detection device, and the conveying chain stops moving; the flipping mechanism 3 is started, so that the flipping arm 32 rotates around the center set on the flipping support seat 31; the flipping arm 32 hidden under the conveying chain at the front of the flipping mechanism 3 rises, lifts the profile group 8 that needs to be flipped and flips it above the lifting mechanism 4, with the profile opening facing upward; during the flipping process, the profile is blocked and positioned by the first step stopper 321 on the flipping arm 32 in the flipping mechanism 3; then the profile opening on the flipping arm 32 is buckled upward onto the lifting platform. In this embodiment, the flipping arm 32 is driven by a hydraulic motor or an electric motor alone, and the swing range is less than 180°.

[0104] (c) The lifting mechanism 4 receives the downward-opening and upward-opening profiles transported by the translation mechanism 2 and the flip mechanism 3, respectively, and stacks them alternately to a specified height on the lifting platform, thus completing the stacking of the profiles.

[0105] (d) After the stacking is completed, the lifting platform moves down to the lowest position, and the stacked profiles are placed on the output roller 5, and the output roller 5 is started to move towards the alignment baffle 6 to make the edges of the profiles flush. Then the output roller 5 is started in the reverse direction, and the stacked steel stack is moved to the baler for baling. Finally, the baled finished products are transported to the collection stand and wait for the crane to lift them.

[0106] It should be noted that the present embodiment adopts the order of incoming materials in which stainless steel profiles that do not need to be flipped and those that need to be flipped appear alternately, but in actual application, it is not limited by the above operation mode. For some profiles, direct translation placement and flip placement do not necessarily have to appear alternately, and can be determined according to the specific situation. It can be translated first and then flipped, or flipped first and then translated, or only one type of translation or flipping is used for palletizing. Therefore, the above description of the palletizing process is only for the convenience of understanding the working principle of the palletizing method of the present invention.

[0107] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
