Description

Technical Field

[0001] The invention relates to the technical field of laser cutting machines, and in particular to a material rack assembly for a laser cutting machine. Background Art

[0002] Laser cutting machines can cut a variety of materials, including but not limited to the following: stainless steel, carbon steel, aluminum and aluminum alloys, tempered glass, acrylic (PMMA), plastics (such as ABS, PVC, polycarbonate, etc.). These materials are generally made into plates and stored in the racks of laser cutting machines. The most widely used racks of laser cutting machines are drawer-type, with multiple layers of pull-out material carts loaded on the racks. When taking materials, just pull out the material cart to take the materials loaded on the material cart.

[0003] When the material cart is pulled out, some materials are easily displaced and tilted on the material cart due to their smooth surface. In order to prevent these materials from falling off, the existing material carts are equipped with guard plates at the edges. However, if the materials are tilted and displaced, if the material cart continues to move normally, it is easy for the materials inside the material cart to hit the guard plates of the material cart, and may even pass through the guard plates and fall off the material cart, causing material loss. Especially when loading tempered glass and some plastic materials, the edges of the materials are easily damaged by impact. When workers pull the material cart, it is difficult to detect the displacement of the materials in time, and it is difficult to avoid material damage in time. Summary of the invention

DETAILED DESCRIPTION

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0039] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example

[0040] Reference Figure 1 , a laser cutting machine material rack assembly is provided, including a frame 100, which has a material storage area 101 and a material retrieving area 102, and the frame 100 is also provided with a track 103 connecting the material storage area 101 and the material retrieving area 102; the material of the laser cutting machine is placed in the material storage area 101, the frame 100 includes a main frame 104, and a frame door 105 that can be unfolded on the main frame 104; the internal space of the main frame 104 constitutes the material storage area 101, and the frame door 105 constitutes the material retrieving area 102 when it is unfolded. In actual use, the width and length of the material need to be smaller than the width and length of the material storage area 101, and also smaller than the width and length of the material retrieving area 102. In normal storage, the frame door 105 is in a closed state, and multiple layers of materials are loaded inside the material storage area 101. When the material needs to be taken out, the frame door 105 is unfolded to form the material retrieving area 102, and the material retrieving area 102 is convenient for taking out the material.

[0041] like Figure 1 and Figure 2 It should be noted that multiple layers of tracks 103 are installed on both the main frame 104 and the frame door 105, and the number of tracks 103 on each layer is two. When the frame door 105 is unfolded, the tracks 103 on the frame door 105 and the tracks 103 on the main frame 104 correspond in position, so that the tracks 103 on the frame door 105 and the tracks 103 on the main frame 104 constitute a track 103 that runs through the material storage area 101 and the material retrieval area 102.

[0042] like Figure 1 and Figure 3 The laser cutting machine material rack assembly includes a material carrier 200, which is movably arranged on the frame 100 through a track 103. The material carrier 200 includes a frame 201 and a roller member 202 installed on the frame 201; the roller member 202 includes an axle 203 rotatably installed on the frame 201, and a wheel body 204 installed on the axle 203; the wheel body 204 can roll along the track 103.

[0043] In this embodiment, the wheel body 204 contacts the upper surface of the track 103. There are four wheel bodies 204 on each frame 201. The four wheel bodies 204 are arranged in pairs. The wheel bodies 204 can help the frame 201 move along the track 103. At the same time, the four wheel bodies 204 play a role in supporting the frame 201.

[0044] The material is placed on the top of the frame 201. When the frame 201 moves, it can drive the material to move, similar to a drawer. A frame 201 is set on each layer of track 103. The frame 201 can store materials on each layer of track 103. When storing, the frame 201 is located in the storage area 101 so that the material is stably located in the storage area 101. When taking out, the frame door 105 is unfolded, and the frame 201 can reach the material taking area 102 through the track 103, so that the material reaches the material taking area 102. Each time the material is taken out, only one frame 201 is needed to reach the material taking area 102, and then the material on the frame 201 is taken down by an external taking device and transported to the cutting station of the cutting machine.

[0045] like Figure 2 The laser cutting machine material rack assembly includes a brake mechanism 300, including a rocker arm 301 installed on the frame 201, and a locking wheel 302 installed on the roller member 202; the rocker arm 301 has a certain displacement ability, and when it is displaced, it can come into contact with the locking wheel 302. When the rocker arm 301 contacts the locking wheel 302, the locking wheel 302 can be locked. Because the locking wheel 302 is installed on the roller member 202, when the locking wheel 302 is locked, the corresponding roller member 202 can be locked.

[0046] like Figure 3 and Figure 5 The laser cutting machine material rack assembly includes a displacement mechanism 400, which is movably arranged on the frame 201, and the displacement mechanism 400 can limit the rocker arm 301; therefore, when the displacement mechanism 400 does not displace, the rocker arm 301 cannot be displaced, and the rocker arm 301 and the locking wheel 302 remain disengaged to prevent the roller member 202 from being locked. The displacement mechanism 400 plays the role of limiting the rocker arm 301. During normal operation, it ensures that the roller member 202 can operate normally, so that the frame 201 can move normally on the track 103.

[0047] like Figure 3 , Figure 5 as well as Fig.11The trigger mechanism 500 is rotatably mounted on the vehicle frame 201. The trigger mechanism 500 includes a force-bearing arm 501 and a limiting arm 502 that interferes with the displacement mechanism 400. The force-bearing arm 501 extends above the vehicle frame 201. When the force-bearing arm 501 is not pressed, the limiting arm 502 releases the interference with the displacement mechanism 400, and the displacement mechanism 400 moves. The swing rod 301 can be displaced and lock the locking wheel 302. There are four trigger mechanisms 500, and the four trigger mechanisms 500 are arranged respectively. At the four corners of the frame 201, when the material is normally placed on the frame 201, the four trigger mechanisms 500 can be compressed, so that the force arms 501 of the four trigger mechanisms 500 are all pressed. When the force arms 501 are pressed, the limit arms 502 can limit the position of the displacement mechanism 400 to prevent the displacement mechanism 400 from being displaced. When the displacement mechanism 400 can be prevented from being displaced, the rocker arm 301 cannot be displaced. At this time, the rocker arm 301 and the locking wheel 302 remain disengaged, and the roller member 202 can operate normally.

[0048] In the process of moving the carriage 201, when the material is displaced significantly, the material will be misplaced and thus cannot press the four trigger mechanisms 500 at the same time. Figure 8 , showing the problem of material displacement error. At this time, the simulated material 700 is displaced and misaligned with the trigger mechanism 500 in the upper left corner of the figure. The force arm 501 of the trigger mechanism 500 in the upper left corner cannot be pressed by the simulated material 700. At this time, the corresponding displacement mechanism 400 is displaced, and the rocker arm 301 is displaced accordingly and contacts the locking wheel 302, locking the locking wheel 302 and thus locking the roller member 202, so that the moving friction of the frame 201 is increased, thereby preventing the continued movement of the frame 201 from causing the simulated material 700 and the edge of the frame 201 to collide.

[0049] It should also be noted that if Figure 5 Not only is there four trigger mechanisms 500 , there are also four displacement mechanisms 400 , and they correspond one to one with the positions of the four trigger mechanisms 500 , and each trigger mechanism 500 limits the corresponding displacement mechanism 400 .

[0050] like Figure 4The trigger mechanism 500 also includes a fixed column 503 fixed on the frame 201, and a turntable 504 rotatably installed on the fixed column 503; the force arm 501 and the limit arm 502 are both installed on the turntable 504, the fixed column 503 can be fixed on the frame 201 by welding, and the turntable 504 is rotatably sleeved on the outer side of the fixed column 503. When the force arm 501 is pressed, the turntable 504 rotates counterclockwise, and the limit arm 502 resists the displacement mechanism 400 to prevent the displacement mechanism 400 from moving. When the material is misaligned with the force arm 501, the turntable 504 rotates clockwise, and the limit arm 502 releases the resistance to the displacement mechanism 400.

[0051] Furthermore, a limiting column 505 is provided on the fixed column 503, and a limiting slot 506 is provided on the turntable 504, and the limiting column 505 extends to the inner side of the limiting slot 506; the fixed column 503 limits the rotation angle of the turntable 504 through the limiting column 505, and through the mass relationship between the force-bearing arm 501 and the limiting arm 502, the mass of the limiting arm 502 is greater than the mass of the force-bearing arm 501, so that the force-bearing arm 501 can naturally extend to the top of the frame 201 without being pressed, and through the limiting column 505 and the limiting slot 506, the turntable 504 can be limited to rotate within a certain angle. Example

[0052] This embodiment is different from the first embodiment in that: Fig. 9 and Fig.10 The brake mechanism 300 also includes a fixed seat 303 installed on the frame 201, and a connecting pin 304 rotatably installed on the fixed seat 303; the end of the connecting pin 304 away from the fixed seat 303 is connected to the swing rod 301; a locking tooth 305 is provided on the swing rod 301, and when the swing rod 301 contacts the locking wheel 302, the locking tooth 305 can lock the locking wheel 302, and a tooth groove is provided on the locking wheel 302.

[0053] Among them, the fixed seat 303 is fixed on the frame 201, one end of the connecting pin 304 is connected to the fixed seat 303 through an axial rotation, and the other end is connected to the rocker arm 301 through an axial rotation. Through the limit of the displacement mechanism 400, the connecting pin 304 is in a vertical state. At this time, when the material and one of the trigger mechanisms 500 are misaligned and the corresponding displacement mechanism 400 is displaced, the limit of the rocker arm 301 is cancelled. At this time, the connecting pin 304 in the vertical state is difficult to maintain the vertical state. The connecting pin 304 rotates relative to the fixed seat 303, driving the rocker arm 301 to displace. When the rocker arm 301 is displaced, the locking teeth 305 on the rocker arm 301 are engaged with the tooth grooves on the locking wheel 302, which can prevent the locking wheel 302 from rotating, thereby achieving the effect of locking the locking wheel 302.

[0054] Specifically, refer to Figure 6 and Figure 7 The displacement mechanism 400 includes a slide bar 401 slidably arranged on the frame 201, a moving column 402 connected to the slide bar 401, a contact head 403 installed on the moving column 402, an anti-tilt body 404 arranged on the slide bar 401, and an elastic member 405 abutting against the contact head 403; when the limiting arm 502 releases the interference with the displacement mechanism 400, the elastic member 405 can push the contact head 403 to drive the moving column 402 and the slide bar 401 to move.

[0055] Under normal conditions, the material presses the force-bearing arm 501, and the limit arm 502 keeps pressing the contact head 403. The elastic member 405 is compressed, wherein the elastic member 405 is a spring, and the anti-tilt body 404 abuts against the end of the swing rod 301, so that the connecting pin 304 remains in a vertical state, and the swing rod 301 cannot be displaced. When the material is misaligned with one of the force-bearing arms 501, the corresponding limit arm 502 releases the pressing state on the contact head 403. At this time, the elastic member 405 pushes the contact head 403, so that the entire The displacement mechanism 400 is displaced, the anti-tilt body 404 is misaligned with the end of the rocker arm 301, the connecting pin 304 cannot remain in a vertical state and rotates, the rocker arm 301 is displaced, and the locking teeth 305 of the rocker arm 301 contact the locking wheel 302 and engage with the tooth grooves on the locking wheel 302, so that the locking wheel 302 is locked, thereby locking the roller member 202, so that the moving friction of the frame 201 is increased, and the continued movement of the frame 201 causes the simulated material 700 to collide with the edge of the frame 201.

[0056] The rest of the structure is the same as that of Example 1. Example

[0057] This embodiment is different from the above embodiment in that: Figure 5 When the material and one of the trigger mechanisms 500 are misaligned, in order to lock the four roller members 202 at the same time, the roller members 202 are arranged in pairs on both sides of the frame 201, and the paired roller members 202 are equipped with paired displacement mechanisms 400; the laser cutting machine material frame assembly also includes a connecting member 600, and the paired displacement mechanisms 400 are connected by the connecting member 600.

[0058] Under normal conditions, when no material is placed, the two displacement mechanisms 400 connected by the connecting member 600 reach a stable state through the elastic members 405 in the two displacement mechanisms 400, that is, the anti-tilt body 404 is kept in contact with the rocker arm 301. At this time, the roller member 202 can also operate normally, so that the frame 201 can also operate normally in an unloaded state.

[0059] When the material is placed, the four force-bearing arms 501 are pressed simultaneously, such as Figure 5Two displacement mechanisms 400 connected by a connecting member 600 form a group, and both ends of a group of displacement mechanisms 400 are respectively limited by the limiting arms 502 of two trigger mechanisms 500, so that the position of the displacement mechanism 400 is fixed and cannot be displaced, and the roller member 202 maintains a stable operating state.

[0060] When the material is displaced and tilted, the material is misaligned with the force-bearing arm 501 of one of the trigger mechanisms 500, but still presses the force-bearing arm 501 of the other trigger mechanism 500, such as Figure 8 , wherein the displacement mechanisms 400 at the upper left corner and the upper right corner are connected as a group through a connecting piece 600. The figure shows the tilted state of the simulated material 700. At this time, the simulated material 700 is displaced and tilted, and is misaligned with the force arm 501 at the upper left corner of the figure. At this time, the force arm 501 at the upper right corner of the figure is still pressed by the simulated material 700. Under the push of the elastic member 405 in the displacement mechanism 400 at the upper left corner and the limit arm 502 at the upper right corner, the two displacement mechanisms 400 in this group move to the left synchronously, and the anti-tilt bodies 404 in the two displacement mechanisms 400 are respectively misaligned with the two rocker arms 301. Therefore, the two rocker arms 301 obtain displacement capability at the same time, and the two rocker arms 301 are displaced, so that multiple locking wheels 302 can be locked at the same time, so that multiple roller members 202 are locked.

[0061] For further reference, Figure 6 and Figure 7 A protrusion 406 is provided on the anti-tilt body 404, and grooves 407 are provided at both ends of the protrusion 406 of the anti-tilt body 404; when the end of the rocker arm 301 contacts the protrusion 406, the rocker arm 301 cannot be displaced, and when the end of the rocker arm 301 contacts the groove 407, the rocker arm 301 can be displaced.

[0062] In the initial state, the end of the rocker arm 301 is in conflict with the protrusion 406, and the protrusion 406 can limit the end of the rocker arm 301. When a group of displacement mechanisms 400 is displaced, the protrusions 406 of the anti-tilt bodies 404 in the two displacement mechanisms 400 in this group are respectively misaligned with the two rocker arms 301, so that the two rocker arms 301 can obtain space for displacement.

[0063] Furthermore, the latching teeth 305 are arranged in pairs on the swing rod 301 , and the locking wheel 302 is located between the paired latching teeth 305 ; both ends of the swing rod 301 are limited by the anti-tilt body 404 .

[0064] In this embodiment, there are four trigger mechanisms 500, four displacement mechanisms 400 and two of them are connected by connecting members 600, and there are two rocker rods 301. The two ends of each rocker rod 301 correspond to a displacement mechanism 400 respectively, that is, the two ends of the rocker rod 301 are limited by the displacement mechanism 400, and the number of fixing seats 303 corresponding to each rocker rod 301 is two, and two pairs of latching teeth 305 are provided on each rocker rod 301. When the rocker rod 301 is displaced, it can drive the two pairs of latching teeth 305 to move, and the two pairs of latching teeth 305 can respectively lock the two locking wheels 302. Therefore, when the two rocker rods 301 both obtain displacement space, the displacement of the two rocker rods 301 can lock the four locking wheels 302, so that the four roller members 202 are all in a locked state, thereby further improving the stability of the brake stop.

[0065] The rest of the structure is the same as that of Example 2.

[0066] In order to provide a concise description of exemplary embodiments, all features of an actual embodiment may not be described (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention).

[0067] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0068] 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 preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be included in the scope of the claims of the present invention.
