Description

Technical Field

[0001] The invention relates to the field of material cart design, and in particular to a material fork module and a material cart. Background Art

[0002] The box-type heat treatment furnace production line is an automated production line composed of multiple box-type heating furnaces, tempering furnaces, quenching tanks, cleaning machines, loading tables, unloading tables and other equipment. The transfer of workpieces between each device is automatically completed by a rail-mounted material car. Each device is arranged in a straight line on one side or both sides along the material car track. The number and size of the material forks of the traditional material car are determined by the specifications of the workpiece. The material forks are fixed on the horizontal moving trolley, and the movement of the material forks is driven by the horizontal moving trolley. The size and number of the material forks are fixed values, that is, a material car can only load and unload workpieces of the same specification and size. Since the workpieces processed by all equipment in the production line are loaded, unloaded and transferred by the same material car, the specifications and sizes of the workpieces processed by all equipment in the entire production line must be consistent with the specifications and sizes of the material forks of the material car. When the equipment is arranged along both sides of the material cart track, the material cart is required to have the function of rotating 180° for loading and unloading. Considering the complexity of the material cart rotation mechanism and the demand for rotation space, this arrangement method is difficult to use for production lines that produce workpieces with larger specifications and sizes. Generally, when the workpiece size is greater than 2mx2m, it is difficult for the equipment to be arranged along both sides of the material cart track. Due to the characteristics of traditional material carts, the box-type heat treatment furnace production line can only process workpieces of the same size and type, which is not flexible enough; for workpieces with larger specifications and sizes, the equipment can only be arranged on one side of the material cart track, which occupies a large area and is not economical. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art that the material cart can only process workpieces of the same specification and size and lacks flexibility, and to provide a material fork module that can transfer workpieces of different sizes.

[0010] At least two first drive shafts are rotatably mounted on the frame and are driven by corresponding first drive motors respectively, and each of the first drive shafts drives the corresponding group of material forks to slide.

[0011] Furthermore, the first driving shaft drives the material fork through the cooperation of a first driving gear and a first rack, the first rack is fixed on the material fork, the first driving gear is fixed on the first driving shaft, and the first driving gear is meshed with the corresponding first rack.

[0012] Another embodiment, the driving module comprises:

[0013] a second driving motor fixed on the frame;

[0016] Alternatively, the driving module includes a plurality of linear driving modules, each of the material forks is independently driven by a corresponding linear driving module, and the linear driving module is a first air cylinder, a hydraulic cylinder or a servo electric cylinder.

[0017] Preferably, the frame comprises:

[0018] A lifting frame, on which a plurality of material forks are slidably mounted in parallel;

[0019] The translation frame is configured to slide linearly along the direction of feeding and picking up materials.

[0020] Furthermore, the translation frame is provided with a linear module for driving the lifting frame to rise and fall, and the translation frame also includes a power module for driving the translation frame to slide linearly.

[0021] Furthermore, the lifting frame is a vertical rectangular frame structure, and a plurality of channels for the material fork to pass through are formed at the lower part of the lifting frame. The plurality of channels are horizontally arranged in parallel, and a plurality of guide rollers are arranged in each channel. The guide rollers are rotatably installed in the channels, and the guide rollers are used to carry the material fork and limit the sliding direction of the material fork.

[0028] 1. In the present application, multiple material forks are used, and the number of material forks required to move the workpiece can be determined according to the size of the workpiece to be loaded and unloaded. When a workpiece with smaller specifications needs to be loaded and unloaded, the driving module only drives a smaller number of material forks into the equipment for loading and unloading; when a workpiece with larger specifications needs to be loaded and unloaded, the driving module drives a larger number of material forks into the equipment for loading and unloading. In this way, the transportation of workpieces of different sizes can be realized, and the applicability is wide.

[0029] 2. When it is necessary to load and unload the workpiece in the equipment on the left side of the material cart, the material fork extends from the left side of the frame to enter the equipment for loading and unloading, and then the frame drives the material fork to move to the right to take the workpiece out of the equipment; when it is necessary to load and unload the workpiece in the equipment on the right side of the material cart, the material fork extends from the right side of the frame to enter the equipment for loading and unloading, and then the frame drives the material fork to move to the left to take the workpiece out of the equipment. In this way, the workpieces on both sides of the material cart can be loaded and unloaded without rotation, and the entire material cart moves back and forth along the ground guide rail to realize the transfer of workpieces between various equipment.

[0041] Embodiment 1:

[0042] Figure 1 The overall structural schematic diagram of the material fork module of the present embodiment is shown, the material fork module of the present embodiment includes a frame, a material fork 10 and a driving module, wherein the frame is configured to be slidably installed, a plurality of material forks 10 are slidably installed in parallel on the frame, the plurality of material forks 10 slide linearly along the material picking and feeding direction, and the driving module is used to group and drive different numbers of material forks 10 to move in different directions relative to the frame to pick up and feed materials.

[0043] That is to say, the multiple material forks 10 in the present embodiment can be grouped according to the size of the workpiece A that needs to be picked up and delivered. When a workpiece A with smaller dimensions needs to be loaded and unloaded, only a smaller number of material forks 10 are allocated to enter the equipment for loading and unloading; when a workpiece A with larger dimensions needs to be loaded and unloaded, a larger number of material forks 10 are allocated to enter the equipment for loading and unloading. For example, in the present embodiment, the four middle material forks 10 are divided into a first group, and the bearing area of ​​the first group of material forks 10 is just matched with the size of the corresponding workpiece A. The other four material forks 10 are divided into a second group. When taking materials, you only need to extend the first group of material forks 10 to take out the workpiece A of the corresponding size. Of course, if the size of the workpiece A is larger, the first and second groups of material forks 10 can be extended at the same time to take the materials.

[0044] It should be noted that, in this embodiment, an implementation method of 8 material forks 10 is given, and they are divided into two groups to adapt to two sizes of workpieces A. However, those skilled in the art should know that the number of material forks 10 can be further increased or the grouping can be increased according to the different sizes of the workpiece A to adapt to workpieces A of more sizes. In this embodiment, only 8 material forks 10 are used as an example to illustrate its working principle, but it is not limited to 8 material forks 10 and the grouping.

[0045] In order to adapt to the functional requirements of the above-mentioned material fork 10, this embodiment also provides a driving module, including a first driving motor and a first driving shaft 21, the first driving motor is fixed on the frame, the first driving shaft 21 is rotatably mounted on the frame and is driven by the corresponding first driving motor respectively, and each of the first driving shafts 21 drives the corresponding group of material forks 10 to slide.

[0046] According to one embodiment of the present invention, see Fig. 9 There are two first drive motors and two first drive shafts 21, and the two first drive shafts 21 are driven by corresponding first drive motors respectively. There are eight material forks 10, and the four middle material forks 10 are configured as the first group, and the four outer material forks 10 are configured as the second group. One of the first drive shafts 21 is used to drive the material forks 10 of the first group, and the other first drive shaft 21 is used to drive the material forks 10 of the second group, so that the material forks 10 of different groups can be rotated according to the size of the workpiece A to perform the feeding movement.

[0047] In this embodiment, the driving of the material fork 10 by the first driving shaft 21 is achieved as follows: the first driving shaft 21 drives the material fork 10 through the first driving gear 22 and the first rack 23. Specifically, the first rack 23 is fixed on the material fork 10, and the first driving gear 22 is fixed on the first driving shaft 21. The first driving gear 22 and the corresponding first rack 23 are meshed, so that the first driving shaft 21 can drive the corresponding material fork 10 to perform linear motion.

[0048] In order to facilitate the picking up and delivering of workpiece A, this embodiment also provides a frame, which includes a lifting frame 41 and a translation frame 42. The material fork 10, the driving module, the lifting frame 41 and the translation frame 42 cooperate with each other to remove the workpiece A from the production line or equipment and then send it to the production line or equipment of the next process.

[0049] According to one embodiment of the present invention, see Figure 1 , 6 and 9, a plurality of material forks 10 are slidably installed in parallel on the lifting frame 41. Specifically, the lifting frame 41 is a vertical rectangular frame structure. A plurality of channels 411 for the material forks 10 to pass through are formed at the lower portion of the lifting frame 41. The plurality of channels 411 are horizontally arranged in parallel, and a plurality of guide rollers 50 are arranged in each channel 411. The guide rollers 50 are rotatably installed in the channels 411. The guide rollers 50 are used to carry the material forks 10 and limit the sliding direction of the material forks 10. In this embodiment, four guide rollers 50 are arranged in each channel 411, and every two guide rollers 50 form a group to form upper and lower limits for the material forks 10. The two groups of guide rollers 50 are separately provided on both sides of the center of the material forks 10 to support and limit the material forks 10, thereby realizing the sliding installation of the material forks 10.

[0050] Preferably, flanges are extended outwardly from both sides of the guide roller 50, and the flanges on both sides limit both sides of the material fork 10, thereby forming a better guiding and limiting effect.

[0051] In order to prevent the first rack 23 from interfering with the guide roller 50, the first rack 23 is fixed to the side of the material fork 10, and a movable gap is left between the first rack 23 and the upper and lower limiting guide rollers 50.

[0052] According to one embodiment of the present invention, the lifting frame 41 and the translation frame 42 are vertically slidably matched. Specifically, the translation frame 42 includes a cross brace 421 and two side plates 422 perpendicular to the cross brace 421. The two sides of the lifting frame 41 are slidably matched with the two side plates 422 through a sliding pair. The cross brace 421 is provided with a second cylinder 43 for driving the lifting frame 41 to rise and fall. In this embodiment, there are two second cylinders 43, the cylinder body of the second cylinder 43 is fixed to the cross brace 421, and the piston rod of the second cylinder 43 is connected to the upper top surface of the lifting frame 41. The two second cylinders 43 drive the lifting frame 41 to rise and fall, thereby driving the workpiece A on the material fork 10 to rise and fall. In this embodiment, the first drive motor and the first drive shaft 21 are both installed on the lifting frame 41 to cooperate with grabbing the workpiece A.

[0053] According to one embodiment of the present invention, see Figure 8 The translation frame 42 is configured to slide linearly along the material picking and feeding direction. Specifically, a plurality of rollers are configured at the bottom of the translation frame 42, and the plurality of rollers are driven by a stepper motor. Of course, the frame body can also adopt other sliding installation structures, such as the cooperation mode of the slider and the slide rail, which is not limited.

[0054] Figure 1-5 The schematic diagram of the material picking steps of the material fork module of this embodiment is shown. When it is necessary to pick up the workpiece A of the equipment on the left side of the material fork module, the material fork 10 extends from the left side of the frame into the equipment to load and unload the material, and then the frame drives the material fork 10 to move to the right to take the workpiece A out of the equipment; when it is necessary to load and unload the workpiece A in the equipment on the right side of the material fork module, the material fork 10 extends from the right side of the frame into the equipment to load and unload the material, and then the frame drives the material fork 10 to move to the left to take the workpiece A out of the equipment. In this way, the workpiece A on both sides of the material fork module can be loaded and unloaded without rotation.

[0055] This embodiment also provides a material cart for transferring workpieces A on the production line. In this embodiment, the processing equipment is located on both sides of the conveyor line, and the material cart is used to transfer the workpiece A between the processing equipment on both sides. In this embodiment, the material cart includes a material cart body 60, and the material cart body 60 moves along the ground guide rail, that is, moves along the direction of the production line. The material cart also includes the above-mentioned material fork module, and the frame of the material fork module is installed on the material cart body 60 and slidably cooperates with the material cart body 60, and the sliding direction is consistent with the sliding direction of the material fork 10.

[0056] According to one embodiment of the present invention, a guide rail is provided on the material cart body 60, and the roller of the translation frame 42 cooperates with the guide rail. The stepper motor drives the roller to move the material fork module as a whole to pick up and feed materials. The material cart body 60 moves along the direction of the production line with the material fork module.

[0057] Figure 1-5 The material taking steps of the material car of the present invention are shown, and the material taking steps of the material car are as follows: ① Referring to Figure 1 , according to the size of the equipment and workpiece A, select the number of material forks 10 entering the equipment. At this time, all material forks 10 are in the initial state of being flush on the left and right; ② Refer to Figure 2 The driving module drives a plurality of material forks 10 (eg Figure 2 The middle 4 material forks 10) move to the left relative to the frame and enter the workpiece fork position in the equipment; ③ Refer to Figure 3 , the lifting frame 41 drives all the material forks 10 to lift, so that the four material forks 10 take the workpiece A out of the equipment; ④ Refer to Figure 4 , driving the translation frame 42 to move to the right, and at the same time, the driving module drives the material fork 10 (for example Figure 4 The four material forks 10 distributed on both sides move leftward relative to the translation frame 42; ⑤ Reference Figure 5, the translation frame 42 moves rightward to the right limit position, and at the same time, the four material forks 10 on both sides that are not involved in forking the workpiece A move leftward to the left limit position relative to the translation frame 42. At this time, the workpiece A is separated from the equipment, and all the material forks 10 return to the initial state of being flush with the left and right. The entire material car moves forward and backward along the ground rail to realize the transfer of the workpiece A between various devices.

[0058] Figure 6-8 The reversing steps of the material car of the present invention are shown, and the reversing steps of the material car are as follows: ① Referring to Figure 6 , workpiece A is on the left side of the material cart. The material cart can complete the loading and unloading of the left workpiece A in this state. The next step is to reverse the material cart to realize the loading and unloading of the right workpiece A; ② Refer to Figure 7 , driving the translation frame 42 to move to the right, while the driving module drives all the material forks 10 to move to the left relative to the translation frame 42; ③ Refer to Figure 8 , the translation frame 42 moves to the right limit position, and at the same time all the material forks 10 also move to the left limit position to complete the reversal.

[0059] It can be seen from the above process that the material fork module always keeps the idle material fork 10 not protruding from the material cart body during the process of picking up and feeding materials, because the idle material fork 10 can be independently controlled and moved in the opposite direction to make way, so that the material cart can smoothly change direction and pick up and feed materials.

[0060] Embodiment 2:

[0061] The material fork module of this embodiment is basically the same as that of the first embodiment, except that the drive module, such as Fig.10 As shown, the driving module of this embodiment includes a second driving motor and a second driving shaft 31. The second driving motor is fixed on the frame. The second driving shaft 31 is driven by the second driving motor. The second driving shaft 31 is provided with a plurality of clutches 32 corresponding to the material forks 10 one by one. The material forks 10 of the corresponding group are selected to be driven through the clutches 32.

[0062] Furthermore, the second driving shaft 31 drives the material fork 10 through the cooperation of the second driving gear 33 and the second rack 34, the second rack 34 is fixed on the material fork 10, the second driving gear 33 is rotatably mounted on the second driving shaft 31, the second driving gear 33 is meshed with the corresponding second rack 34, the clutch 32 is also fixedly mounted on the second driving shaft 31, the second driving gear 33 and the clutch 32 correspond one to one, the second driving shaft 31 transmits power to the second driving gear 33 through the clutch 32 to drive the corresponding group of material forks 10.

[0063] The clutch 32 in this embodiment is an electromagnetic clutch, which includes a housing fixed on the second drive shaft 31 and a coil frame, a linkage disk and an armature built into the housing. The coil is wound on the coil frame, the linkage disk is sleeved on the second drive shaft 31 and has an interference fit, and the armature is fixed to one side of the second driving gear 33 through a disc spring. Specifically, the second driving gear 33 is rotatably mounted on the second drive shaft 31 through a bearing, and a disc spring is provided on the surface of the second driving gear 33 close to the clutch 32. The armature is installed on the elastic active part of the disc spring, and one part of the armature is opposite to the linkage disk, and the other part is opposite to the coil. When the coil is energized, the armature is attracted to the armature so that the armature is pressed on the linkage disk. At this time, the second drive shaft 31 transmits power to the second driving gear 33 through the clutch 32. When the coil is de-energized, the armature is reset under the action of the disc spring, and the linkage is released.

[0064] Embodiment three:

[0065] The material fork module of this embodiment is basically the same as that of the first embodiment, and the difference lies in the drive module.

The extension direction of the first cylinder is consistent with the moving direction of the material fork 10, and the material fork 10 can be driven to move in both directions by the first cylinder.

[0066] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention.
