Description

Technical Field

[0001] The invention relates to the technical field of disc destacking machines, and in particular to a track-type shift fork guide mechanism and a disc destacking machine. Background Art

[0002] In factories, logistics, warehousing and other fields, trays are used as carriers of goods or products. In the traditional mode, when idle, trays are usually stacked one by one or layer by layer by manual stacking. On the contrary, when entering the assembly line for production activities, the stacked trays need to be manually disassembled and put into the assembly line. This traditional method not only has high labor intensity for workers, but also seriously affects production efficiency.

[0003] In the prior art, in order to solve the problem of manual stacking, pallet unpacking machines and pallet stacking machines emerged, but they still had a single mechanical function. Later, a pallet unpacking and stacking machine that unified the two appeared. For example, the Chinese utility model patent with patent number ZL202021604482.9 discloses an automatic pallet unpacking and stacking machine, including a lifting motor and a power frame. A lifting motor is fixed on the top of the power frame. The power output end of the lifting motor is sequentially coupled with a transmission shaft through a motor chain and a motor sprocket, and both ends of the transmission shaft are coupled with a pallet lifting mechanism. The working principle of the pallet destacking machine is similar to the above: taking the pallet stacking process as an example, first, the lifting mechanism lifts the first pallet to the highest point, then the fork extends to the bottom or side slot of the pallet, then the lifting mechanism descends to the lowest point, and as the lifting mechanism descends, the pallet drops slightly until it is lifted by the fork; then, the lifting mechanism lifts the second pallet to support the first pallet, and slightly lifts the two pallets so that the fork can retract smoothly, then the lifting mechanism continues to lift the two pallets to the highest point, and then the fork extends again to insert into the bottom or side slot of the second pallet; and so on, the pallet stacking work is completed.

[0004] That is, the lifting (lifting) mechanism and the fork mechanism of the existing destacking machine need to use two independent power devices, that is, the coordination of the two actions needs to be controlled by a program. Once the program goes wrong, the equipment will not work properly, and even cause damage to the equipment, and the stability is poor. At the same time, when the two mechanisms are working normally, they need to perform multiple actions in sequence, and the working efficiency is low. Summary of the invention

[0005] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art and to provide a track-type fork guide mechanism and a stacking machine, which can use a set of power devices to realize the stacking action and ensure the stability and efficiency of the equipment.

[0006] The objective of the present invention is achieved through the following technical solutions:

[0007] A track-type fork guide mechanism comprises a guide track and a guide assembly, wherein the guide track comprises an upper vertical rail and a lower vertical rail which are spaced apart and staggered up and down, an upper inclined rail connecting the middle of the upper vertical rail with the upper end of the lower vertical rail, and a lower inclined rail connecting the lower end of the upper vertical rail with the middle of the lower vertical rail; the guide assembly comprises an upper guide member which blocks the upper end outlet of the upper inclined rail or the lower side of the upper vertical rail where the upper inclined rail is connected, and a lower guide member which blocks the lower end outlet of the lower inclined rail or the upper side of the lower vertical rail where the lower inclined rail is connected.

[0008] Working principle of the present invention: As we know, to lift the pallet, the forks on opposite sides need to perform symmetrical actions at the same time. To simplify the description, the following description will be made by taking the action of the forks on one side as an example.

[0009] When pallet stacking begins, the shift fork is at the lowest point of the lower vertical rail, and the upper guide and lower guide block the upper inclined rail and lower vertical rail respectively. Under the action of the jacking (lifting) mechanism, the shift fork rises along the guide rail, first passing through the lower section of the lower vertical rail. Since the lower vertical rail is blocked, it then enters the lower inclined rail and follows the path of the lower inclined rail, obliquely inserting into the slot on the side of the pallet; then the shift fork enters the upper vertical rail and lifts the pallet vertically upward along the upper vertical rail. Since the exit of the upper inclined rail is blocked, the shift fork will not slide into the upper inclined rail, but will follow the upper vertical rail to the highest point. At this time, a new pallet is transported from below by means of a chain conveyor or the like. Then, the shift fork begins to descend, and at the same time, the upper guide and lower guide switch to block the upper vertical rail and lower inclined rail respectively. The fork passes through the upper section of the upper vertical rail downwards. At this time, the pallet on the fork has been lowered to the new pallet below. Since the upper vertical rail is blocked, the fork then follows the path of the upper inclined rail and exits the slot of the first pallet diagonally downwards; then the fork enters the lower vertical rail and descends to the lowest point along the lower vertical rail. When the fork moves for the second time, it is inserted into the slot of the second pallet below and lifts the two pallets at the same time. Then the third pallet is transported from below, and so on, completing the entire pallet stacking work.

[0010] At the beginning of pallet removal, the shift fork holding several pallets is at the highest point of the upper vertical rail, and the upper guide and lower guide block the upper inclined rail and the lower vertical rail respectively. The shift fork first descends along the upper vertical rail to the lowest point of the upper vertical rail, at which time the entire stack of pallets is lowered to the conveying equipment such as the chain conveyor below and supported by the conveying equipment below; then the shift fork enters the lower inclined rail and exits the slot of the first pallet at the lower end along the path of the lower inclined rail; then the shift fork enters the lower vertical rail and descends to the lowest point along the lower vertical rail. At this time, the upper guide and the lower guide are switched to block the upper vertical rail and the lower inclined rail respectively. The fork starts to rise along the lower vertical rail until it reaches the highest point of the lower vertical rail, then enters the upper inclined rail and inserts obliquely upward along the path of the upper inclined rail into the slot of the second pallet at the lower end, then enters the upper vertical rail and continues to rise along the upper vertical rail to lift the second pallet at the lower end and all the pallets on it together, even if they are no longer pressed on the first pallet at the lower end, so that the chain conveyor and other conveying equipment can convey the first pallet at the lower end, that is, the dismantling of the first pallet at the lower end is completed. Repeat the above actions to complete the entire dismantling work.

[0011] It should also be noted that there may be many specific structures and switching methods for the upper guide member and the lower guide member, and at least they may be implemented by motor drive.

[0012] As a preferred embodiment of the present invention, the upper guide member is rotatably connected to the angle between the upper inclined rail and the upper vertical rail, the lower guide member is rotatably connected to the angle between the lower inclined rail and the lower vertical rail, the guide assembly also includes an upper limit member for limiting the swing of the upper guide member between the upper inclined rail and the upper vertical rail, a lower limit member for limiting the swing of the lower guide member between the lower inclined rail and the lower vertical rail, and a reset structure for resetting the upper guide member and the lower guide member to one end of the swing range, and the reset points of the upper guide member and the lower guide member are respectively at the upper inclined rail and the lower inclined rail, or at the upper vertical rail and the lower vertical rail. Working principle: Taking the stacking process as an example, the stacking process requires the reset points of the upper guide and the lower guide to be at the upper vertical rail and the lower vertical rail respectively. The fork starts to move upward from the lowest point of the lower vertical rail. Since the lower guide is reset at the lower vertical rail and can only swing to the side of the lower inclined rail, the fork cannot push the lower guide upward, but can only continue to move upward along the lower inclined rail, then enter the upper vertical rail and move upward along the upper vertical rail. Although the upper guide is reset at the upper vertical rail, it can swing to the side of the upper inclined rail, so the fork can push the upper guide and continue to move upward along the upper vertical rail to the highest point. Then the fork moves downward. After the fork passes through the upper guide, the upper guide has returned to the upper vertical rail under the action of the reset structure, and it cannot continue to swing downward. Therefore, the fork can only enter the upper inclined rail and enter the lower vertical rail from the upper inclined rail to continue to move downward. Although the lower guide is reset at the lower vertical rail, it can swing to the side of the lower inclined rail, so the fork can push the lower guide downward until the lowest point of the lower vertical rail. When the shift fork passes through the lower guide, the lower guide is reset to the lower vertical rail. As described above, the swing and reset structure of the guide makes it possible to automatically achieve accurate guidance of the shift fork without the need for the motor drive controller to switch the blocking state. In addition, the reset structure can at least be implemented using a common torsion spring.

[0013] As a preferred embodiment of the present invention, the reset structure includes two swing arms connected to the swing shaft of the upper guide member and the swing shaft of the lower guide member, and a counterweight block disposed at the end of the swing arm. The structure realizes the reset of the guide member through the swing arm and the counterweight block, and is more convenient to switch the reset point, and only the initial position of the swing arm and the counterweight block needs to be changed to the opposite side.

[0014] As a preferred embodiment of the present invention, both opposite sides of the end of the swing shaft are provided with positioning surfaces, and the swing arm is provided with a positioning hole matching the positioning surface structure, so that the switching operation of the guide member reset point is more convenient, and the swing arm can be directly turned 180 degrees.

[0015] As a preferred embodiment of the present invention, when the upper guide member blocks the upper end outlet of the upper inclined rail, one side thereof is aligned with an inner side of the upper vertical rail; when the lower guide member blocks the lower end outlet of the lower inclined rail, one side thereof is aligned with an inner side of the lower inclined rail to ensure the smoothness of the movement of the fork along the guide rail and prevent jamming.

[0016] The present invention also provides a disc destacking machine, comprising a supporting frame, a lifting mechanism, and a fork mechanism. The fork mechanism comprises a connecting plate with one end rotatably connected to a lifting frame in the lifting mechanism, a fork arranged at the other end of the connecting plate, and a guide shaft and a guide bearing arranged on one side of the fork; the support frame is provided with a track-type fork guide mechanism as described above on the side of the connecting plate, and the guide bearing cooperates with the guide track.

[0017] As a preferred embodiment of the present invention, two connecting plates are provided on opposite sides of the jacking frame, and a synchronous connecting frame is provided between the two connecting plates on the same side to ensure the synchronization and structural stability of the two shift forks on the same side.

[0018] As a preferred embodiment of the present invention, a lifting bearing is further provided on the guide shaft, and a shaping mechanism is provided above the lifting bearing, and the shaping mechanism includes a mounting plate, a linkage frame, and a push rod; the two ends of the linkage frame are rotatably connected to the mounting plate and the push rod respectively, and the mounting plate and the linkage frame have at least two groups. The shaping mechanism does not require a separate driving device, and when the lifting bearing moves upward, the linkage frame is lifted, and the vertical distance between the push rod and the rotating shaft of the linkage frame is changed through the rotation of the linkage frame, so that the push rod is pushed toward one side of the pallet to shape the entire stack of pallets.

[0019] As a preferred embodiment of the present invention, a limit shaft is provided on the mounting plate, and an arc-shaped limit groove cooperating with the limit shaft is provided on the linkage frame to limit the rotation range of the linkage frame, thereby ensuring the stability of the push rod movement range and avoiding interference with other components.

[0020] As a preferred embodiment of the present invention, the lifting mechanism includes a lifting motor, two lifting shafts connected to the output end of the lifting motor, crank arms arranged at both ends of the lifting shafts, lifting rollers arranged at the ends of the crank arms, a lifting frame arranged above the four lifting rollers, and a plurality of guide columns connected to the lifting frame. The lifting frame can be repeatedly lifted and lowered by rotating the crank arms, that is, the lifting motor can always rotate in one direction.

[0021] The advantages of the present invention are:

[0022] 1. A set of power devices can be used to realize the disassembly and stacking action to ensure the stability and efficiency of the equipment;

[0023] 2. The track-type fork guide mechanism is cleverly designed to automatically guide the fork to complete the stacking or disassembly of the discs;

[0024] 3. The reset structure is realized by swing arm and counterweight, which is more convenient for switching the reset point of the guide;

[0025] 4. The shaping mechanism does not require a separate driving device, and relies on the driving effect of the shift fork to achieve the shaping of the pallet. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] like Figure 1-8As shown, a rail-type fork guide mechanism includes a guide rail and a guide assembly, wherein the guide rail includes an upper vertical rail 11 and a lower vertical rail 12 that are spaced and staggered up and down, an upper inclined rail 21 connecting the middle of the upper vertical rail 11 and the upper end of the lower vertical rail 12, and a lower inclined rail 22 connecting the lower end of the upper vertical rail 11 and the middle of the lower vertical rail 12; the guide assembly includes an upper guide member 31 rotatably connected to the angle between the upper inclined rail 21 and the upper vertical rail 11, a lower guide member 32 rotatably connected to the angle between the lower inclined rail 22 and the lower vertical rail 12, an upper limit member for limiting the upper guide member 31 from swinging between the upper inclined rail 21 and the upper vertical rail 11, a lower limit member for limiting the lower guide member 32 from swinging between the lower inclined rail 22 and the lower vertical rail 11, and a reset structure for resetting the upper guide member 31 and the lower guide member 32 to one end of the swing range.

[0040] Among them, the upper limit member includes two upper limit posts 41 respectively arranged on the two sides far away from the upper inclined rail 21 and the upper vertical rail 11, that is, the upper guide member 31 can only swing between the two upper limit posts 41; and, when the upper guide member 31 is close to the upper limit post on the side of the upper inclined rail 21, the upper guide member 31 is in a vertical state, and one side of the upper guide member 31 is aligned with an inner side of the upper vertical rail 11; when the upper guide member 31 is close to the upper limit post on the side of the upper vertical rail 11, the upper guide member 31 is in an inclined state, and one side of the upper guide member 31 is aligned with an inner side of the upper inclined rail 21. Similarly, the lower limit member includes two lower limit posts 42 respectively arranged on the two sides far away from the lower inclined rail 22 and the lower vertical rail 12, that is, the lower guide member 32 can only swing between the two lower limit posts 42. Furthermore, when the lower guide member 32 is close to the lower limit post on the side of the lower inclined rail 22, the lower guide member 32 is in a vertical state, and one side of the lower guide member 32 is aligned with an inner side of the lower vertical rail 12; when the lower guide member 32 is close to the lower limit post on the side of the lower vertical rail 12, the lower guide member 32 is in an inclined state, and one side of the lower guide member 32 is aligned with an inner side of the lower inclined rail 22. This ensures the smoothness of the fork moving along the guide rail.

[0041] The reset structure specifically includes two swing arms 51 respectively connected to the swing shaft of the upper guide member 31 and the swing shaft of the lower guide member 32, and a counterweight block 52 arranged at the end of the swing arm 51, that is, the guide member is always close to the limit column on one side through the gravity of the counterweight block 52, and the shift fork can push the guide member to the limit column on the other side as long as it overcomes the gravity of the counterweight block 52 and the swing arm 51, and after passing the guide member, the guide member automatically resets to prevent the shift fork from pushing the guide member from the other side, thereby realizing unidirectional conduction at the guide member. Since the reset structure can only make the reset point of the guide member at one of the limit columns at the same time, and the requirements for the reset point of the guide member in the process of disassembling and stacking the disc are different, it is necessary to change its direction by disassembling and assembling the swing arm 51, so as to change the reset point of the guide member. In order to simplify the disassembly and assembly process of the swing arm 51, positioning surfaces are provided on both sides opposite to each other at the end of the swing shaft, and a positioning hole matching the positioning surface structure is provided on the swing arm 51, so there is no need to spend time to determine the installation position or angle of the swing arm 51 on the swing shaft, and the swing arm 51 can be directly turned 180 degrees.

[0042] The working principle of the track-type fork guide mechanism: We know that to lift the pallet, the forks on the opposite sides need to perform symmetrical actions at the same time. In order to simplify the description, the following is explained using the action of the fork on one side as an example.

[0043] When stacking starts, Figure 1 As shown, the shift fork is at the lowest point of the lower vertical rail 12, and the reset points of the upper guide 31 and the lower guide 32 are respectively at the upper vertical rail 11 and the lower vertical rail 12. The shift fork rises along the guide rail under the action of the lifting mechanism, and first passes through the lower section of the lower vertical rail 12. Since the lower vertical rail 12 is blocked by the lower guide 32 and the lower guide 32 cannot be pushed upward, the shift fork enters the lower inclined rail 22 along the lower guide 32, and is inserted obliquely upward into the slot 101 on the side of the pallet 10 along the path of the lower inclined rail 22; then the shift fork enters the upper vertical rail 11, and lifts the pallet vertically upward along the upper vertical rail 11. Although the upper guide 31 is at the upper vertical rail 11, the shift fork can push it to the upper inclined rail 21, as shown in FIG. Figure 3As described above, the shift fork can continue to rise along the upper vertical rail 11 to the highest point. And when the shift fork passes through the upper guide 31, the upper guide 31 is reset to the upper vertical rail 11 under the action of the counterweight. At this time, a new pallet is transported from below by means of a chain conveyor 9 or the like. Then, the shift fork begins to descend along the upper vertical rail 11 until it reaches the upper guide 31. At this time, the pallet on the shift fork has already dropped to the new pallet below, and because the upper guide 31 cannot be pushed downward any further, the shift fork can only enter the upper inclined rail 21 along the upper guide 31. The shift fork then follows the path of the upper inclined rail 21 and exits the slot 101 of the first pallet obliquely downward. Then the shift fork enters the lower vertical rail 12, and descends along the lower vertical rail 12 to the lower guide 32. After the lower guide 32 is pushed open to one side of the lower inclined rail 22, as shown in FIG. Figure 4 As shown, the shift fork continues to drop to the lowest point, and the lower guide member 32 is reset to the lower vertical rail 12. When the shift fork moves for the second time, it is inserted into the slot of the second pallet below, and the two pallets are lifted at the same time, and then the third pallet is transported from below, and so on, to complete the whole stacking work.

[0044] When the pallets are removed, the shift fork is holding several pallets at the highest point of the upper vertical rail. The swing arm 51 is disassembled and rotated 180 degrees so that the reset points of the upper guide member 31 and the lower guide member 32 are respectively at the upper inclined rail 21 and the lower inclined rail 22. Figure 5 The shift fork first descends along the upper vertical rail 11 to the lowest point of the upper vertical rail 11, at which time the entire stack of pallets falls onto the conveying equipment such as the chain conveyor below and is supported by the conveying equipment below; then the shift fork enters the lower inclined rail 22 and exits the slot 101 of the first pallet 10 at the lower end obliquely downward along the path of the lower inclined rail 22; then the shift fork pushes the lower guide member 32 to the side of the lower vertical rail 12, as shown in FIG. Figure 7 As shown in the figure, the fork enters the lower vertical rail 12 and descends to the lowest point along the lower vertical rail 12, and the lower guide member 32 is reset to the lower inclined rail 22. Then, the fork starts to rise along the lower vertical rail 12 until it reaches the highest point of the lower vertical rail 12, and then the fork enters the upper inclined rail 21 and is inserted obliquely upward along the path of the upper inclined rail 21 into the slot of the second tray at the lower end, and then the fork pushes the upper guide member 31 to the side of the upper vertical rail 11, as shown in the figure. Figure 8As shown, the upper vertical rail 11 is entered, and the upper vertical rail 11 continues to rise to lift the second pallet at the lower end and all the pallets thereon together, even if they are no longer pressed on the first pallet at the lower end, so that the chain conveyor and other conveying equipment can convey the first pallet at the lower end, that is, the disassembly of the first pallet at the lower end is completed. Repeat the above actions to complete the entire disassembly. It should be noted that generally, the disassembly and stacking machine will only use one of the disassembly or stacking functions at the same time, and there is no need to switch functions frequently, so the above-mentioned switching of the disassembly or stacking functions by disassembling the swing arm will not affect the working efficiency of the equipment; at the same time, the disassembly and assembly of the swing arm is simple and fast, and only the nut needs to be unscrewed, the swing arm is removed, and it can be reinstalled by turning 180 degrees.

[0045] The present invention also provides a disc destacking machine, such as Fig. 9 and 10 As shown, it includes a support frame, a lifting mechanism, and a fork mechanism, wherein the support frame is mainly composed of four columns 51 and a crossbeam 52 arranged between the columns 51. The lifting mechanism is arranged at the lower part of the support frame, including a lifting motor 61, two lifting shafts 62 connected to the output end of the lifting motor 61 through a sprocket chain transmission, a crank arm 63 arranged at both ends of the lifting shaft 62, a lifting roller 64 arranged at the end of the crank arm 63, a lifting frame 65 arranged above the four lifting rollers 64, and four guide columns 66 connected to the lifting frame 65. That is, the lifting motor 61 always keeps rotating in one direction, and the reciprocating lifting motion of the lifting frame 65 can be realized by the rotation of the crank arm 63. The fork mechanism includes a connecting plate 71 with one end rotatably connected to the lifting frame 65, a fork 72 arranged at the other end of the connecting plate 71, a guide shaft 73 and a guide bearing 74 arranged on one side of the fork 72. There are four fork mechanisms, two in each group, which are arranged on opposite sides of the support frame, that is, two groups of forks are inserted into slots on both sides of the pallet respectively; at the same time, the two fork mechanisms in each group are respectively close to the opposite sides of the two columns 51, and the opposite sides of the two columns 51 are provided with the above-mentioned track-type fork guide mechanism, and the guide bearing 74 cooperates with the guide track. In order to ensure the synchronization and structural stability of the two forks 72 on the same side, two connecting plates 71 are provided on the opposite sides of the jacking frame, and a synchronous connecting frame 75 is provided between the two connecting plates 71 on the same side.

[0046] In addition, shaping mechanisms are provided on the opposite sides of the two uprights 51 on the same side. Fig.11As shown, it includes two upper and lower mounting plates 81, a linkage frame 82 with one end rotatably connected to the mounting plate 81, and a push rod 83 rotatably connected to the other ends of the upper and lower linkage frames 82. The lower mounting plate is located above the guide rail, and a jacking bearing 84 is further provided on the portion of the guide shaft 73 outside the guide rail. When the guide shaft 73 moves upward to the upper section of the upper vertical rail 11, the jacking bearing 84 jacks up the linkage frame 82 to a horizontal state, thereby pushing the push rod 83 into the support frame for a certain distance, as shown in FIG. Fig.12 As shown, the tray 10 is squeezed to a certain extent on the side, and four push rods 83 on both sides of the tray are squeezed toward the middle at the same time to achieve the shaping of the whole stack of trays. In addition, the shaping mechanism does not need a separate driving device, and the shaping action can be achieved only by the driving of the fork mechanism, which is lower in cost. In order to limit the swing range of the linkage frame 82 and avoid interference with other components, a limiting shaft 85 is provided on the mounting plate 81, and an arc-shaped limiting groove 86 that matches the limiting shaft 85 is provided on the linkage frame 82.

[0047] Finally, the use of the stacking machine generally requires the use of a conveying device such as a chain machine 9. The chain machine passes through the support frame, and its conveying platform is located above the highest position of the jacking frame, so as to convey the pallets 10 in sequence when stacking the pallets, and convey the pallets away in sequence when unpacking the pallets. The chain machine is a conventional device, and its specific structure is not described in detail here.

[0048] The working principle of the present pallet stacking machine is as follows: when stacking pallets, the chain machine 9 transports the first pallet 10 into the pallet stacking machine, the lifting mechanism is activated, and the fork mechanism is driven to rise and fall cyclically through the lifting frame, and the fork mechanism repeats the stacking action under the action of the guide track. The specific stacking principle is the same as the working principle of the above-mentioned track-type fork guide mechanism, which will not be described in detail here. In addition, during each rise of the fork, the linkage frame will be lifted up, so that the push rod squeezes the two sides of the pallet 10 to achieve automatic shaping. The process of removing pallets is also the same as the working principle of the above-mentioned track-type fork guide mechanism, which will not be described in detail.

[0049] The above is only a preferred specific embodiment of the present invention, which is an implementation method based on the overall concept of the present invention, and the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
