Description

Chain type shifting fork guide mechanism and disc disassembling and stacking machine
Technical Field
The invention relates to the technical field of disc disassembling and stacking machines, in particular to a chain type shifting fork guide mechanism and a disc disassembling and stacking machine.
Background
In the fields of factories, logistics, warehousing and the like, the disk cartridge is applied as a carrier for goods or products. In a traditional mode, when the disc cartridge is idle, the disc cartridge is stacked one by one or layer by layer in a manual stacking mode, otherwise, when the production process enters the assembly line operation, the stacked disc cartridge needs to be manually re-detached and then put into the assembly line. This kind of traditional mode, not only workman's manipulation intensity is big, and serious influence production efficiency moreover.
In the prior art, in order to solve the problem of manual stacking, a tray detaching machine and a tray stacking machine appear at the beginning of transportation, but the mechanical function is single, and then the tray detaching and stacking machine which integrates the tray detaching machine and the tray stacking machine appears. Chinese utility model patent No. ZL202021604482.9 discloses an automatic tear dish machine open, including promoting motor, power frame's top is fixed with the promotion motor, the power take off end that promotes the motor loops through motor chain, motor sprocket and transmission shaft transmission cooperation, the both ends of transmission shaft all cooperate with a tray hoist mechanism transmission. The operation principle of the tray splitting and stacking machine is similar to that of the tray splitting and stacking machine: taking the disc stacking process as an example, firstly, the lifting mechanism lifts the highest point of a first tray, then the shifting fork extends to the bottom of the tray or a side slot, then the lifting mechanism descends to the lowest point, and the tray slightly descends along with the descending of the lifting mechanism until the tray is lifted by the shifting fork; then, the lifting mechanism lifts the second tray to abut against the first tray and slightly jacks up the two trays so that the shifting fork can smoothly retract, then the lifting mechanism continues to lift the two trays to the highest point, and then the shifting fork extends out again to be inserted into a bottom slot or a side slot of the second tray; and by parity of reasoning, the disc stacking work is completed.
That is, the lifting (jacking) mechanism and the shifting fork mechanism of the existing tray disassembling and stacking machine need to adopt two sets of independent power devices, namely, the cooperation of the lifting (jacking) mechanism and the shifting fork mechanism in action needs to be controlled by a program, and once the program makes mistakes, the equipment cannot normally work, even the equipment is damaged, and the stability is poor. Meanwhile, when the two mechanisms work normally, a plurality of actions need to be carried out in sequence, and the working efficiency is low.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provides a chain type shifting fork guide mechanism and a disc folding and unfolding machine, which can realize the disc folding and unfolding action by adopting a set of power device and ensure the working stability and efficiency of equipment.
The purpose of the invention is realized by the following technical scheme:
a chain type shifting fork guide mechanism comprises at least two groups of guide components which synchronously drive a shifting fork to act; the guide assembly comprises a plurality of guide chain wheels, a guide chain and a guide connecting piece, wherein the guide chain comprises a first translation section, a second translation section arranged above the first translation section, a first lifting section connected with the same side ends of the first translation section and the second translation section, a second lifting section connected with the other end of the first translation section, and a third lifting section connected with the second translation section and the second lifting section, the length of the first translation section is greater than that of the second translation section, and the length of the second lifting section is greater than that of the first lifting section; the guide chain wheels are respectively matched with the joints of adjacent sections of the guide chain, one end of the guide connecting piece is fixedly connected to the guide chain, and the other end of the guide connecting piece is rotatably connected to the shifting fork; the rotating connecting shaft center of the guide connecting piece and the shifting fork is positioned on the inner side of the guide chain, and the distance between the rotating connecting shaft center of the guide connecting piece and the shifting fork and the guide chain is equal to the distance between the rotating shaft center of the guide chain wheel and the guide chain.
The working principle of the invention is as follows: it is known that to lift a pallet, the forks on opposite sides must be symmetrically operated at the same time, and for the sake of simplicity, the operation of the forks on one side will be described below as an example.
When disc stacking starts, the shifting fork is positioned at the first translation section close to the first lifting section, firstly, the shifting fork moves to the second lifting section along the first translation section, and along with the process, the shifting fork is inserted into a slot on the side surface of the first tray; then, the shifting fork ascends along the second lifting section and lifts the first tray until the highest point is reached; at the moment, a second tray is conveyed from the lower part of the first tray by a chain machine and the like; then, the shifting fork descends along the third lifting section, and the first tray is placed on the second tray; then, the shifting fork moves to the first lifting section along the second translation section so as to withdraw from the slot on the side surface of the first tray; and finally, the shifting fork descends to the lowest point along the first lifting section. Then, the shifting fork repeats the actions, the second tray at the bottom is inserted in the second action, the two trays are lifted, and finally the lower parts of the two trays are conveyed to the third tray. And the rest can be done in the same way to complete the whole disc stacking work.
When the tray is disassembled, the guide chain rotates reversely, the shifting fork is positioned at the highest point and supports a plurality of stacked trays; firstly, the shifting fork descends to the lowest point along the second lifting section, and at the moment, the upper tray of the shifting fork descends to a conveying platform such as a chain machine; then the shifting fork moves to the first lifting section along the first translation section so as to withdraw from the slot of the tray; then the shifting fork rises to the second translation section along the first lifting section and then moves to the third lifting section along the second translation section, and in the translation process, the shifting fork is inserted into a slot of a second tray at the lower end; and then the shifting fork rises to the highest point along the third lifting section to lift the second tray at the lower end and all trays on the second tray, so that the first tray at the lower end is independently positioned on the conveying table, the conveying table can convey the first tray away, and tray detaching work of the first tray is also finished. And by parity of reasoning, the whole disc disassembling work is completed.
It should be noted that, because the rotation connecting axis of the guide connecting piece and the shifting fork is positioned at the inner side of the guide chain, and the distance between the rotation connecting axis of the guide connecting piece and the shifting fork and the guide chain is equal to the distance between the rotation axis of the guide chain wheel and the guide chain. When the guide connecting piece passes through the corner, the guide connecting piece cannot drive the shifting fork to rotate together, wherein the guide connecting piece can independently rotate 90 degrees when passing through the joint of the second translation section and the first lifting section, the joint of the first lifting section and the first translation section, and the joint of the first translation section and the second lifting section, and can independently rotate 180 degrees when passing through the joint of the second lifting section and the third lifting section; in the process that the guide connecting piece rotates independently, the shifting forks can keep in place, namely, the shifting forks only perform translation or lifting actions when passing through the plurality of connecting positions, so that the stability of the shifting forks is ensured; particularly, the highest point is at the joint of the second lifting section and the third lifting section, the shifting fork is certain to hold the tray at the highest point, and if the shifting fork is translated (in the plugging and unplugging direction), potential safety hazards such as displacement of the tray and the like are caused by friction force between the shifting fork and the shifting fork. Of course, inevitably, at the junction of the second and third translating sections, since the corner is inward, i.e. the guide sprocket is outside the guide chain and the guide link is inside the guide chain, the guide link cannot rotate at this point, i.e. the fork needs to follow the guide link in a small arc. However, the end of the process of inserting the shift fork into the tray slot, or the beginning of the process of withdrawing the shift fork from the tray slot, can be designed by the size, so that the shift fork does not contact with the upper and lower side walls of the tray slot in the arc motion process (the height of the slot is certainly much larger than the thickness of the shift fork). Therefore, only one place needs to be correspondingly dimensioned, and other four places do not need to be specially processed.
Preferably, two adjacent pin shafts on the guide chain are extension pin shafts, and the guide connecting piece is provided with two pin holes and is fixed on the two extension pin shafts through a chain plate. The connecting mode is simple in structure and more convenient to disassemble and assemble.
Preferably, the guide connecting piece comprises a chain connecting block and a shifting fork connecting plate which are adjacently connected, the thickness of the chain connecting block is larger than that of the shifting fork connecting plate, and the shifting fork connecting plate is flush with the side surface of the chain connecting block, which is back to the guide chain. So that a sufficient distance exists between the shifting fork connecting plate and the guide chain, and the interference is avoided.
Preferably, the guide assemblies are provided with two groups which are distributed up and down, at least one guide chain wheel in each group of guide assemblies is a double-row chain wheel, and the two groups of guide assemblies are in transmission connection at the double-row chain wheel through a chain so as to ensure that the two groups of guide assemblies perform synchronous and equidirectional actions.
The invention also provides an unfolding and folding disc machine, which comprises a supporting frame, a driving mechanism, the chain type shifting fork guide mechanism and the shifting fork; the chain type shifting fork guide mechanisms are symmetrically arranged on two opposite sides of the supporting frame, the driving mechanism synchronously drives the chain type shifting fork guide mechanisms on the opposite sides to reversely move, and the shifting forks are connected with at least two guide connecting pieces in the same group of chain type shifting fork guide mechanisms.
Preferably, the driving mechanism comprises a driving motor, a first transmission shaft connected to the output end of the driving motor in a transmission manner through a chain wheel and chain assembly, a second transmission shaft connected to the first transmission shaft in a gear meshing transmission manner, and a transmission chain connected to each transmission shaft through a chain wheel; each transmission chain is connected with one guide chain wheel in a transmission mode. The driving mechanism drives the two transmission shafts to rotate reversely through a transmission mode of gear engagement, so that the chain type shifting fork guide mechanisms on the opposite sides are driven to do reverse motion, namely symmetrical motion.
Preferably, two groups of chain type shifting fork guide mechanisms are oppositely arranged on the same side of the supporting frame, a synchronizing shaft is fixedly connected between the two oppositely arranged guide connecting pieces, and the shifting fork is rotationally connected to the synchronizing shaft, so that the action synchronism of the two groups of chain type shifting fork guide mechanisms on the same side is ensured, and the overall structural strength of the shifting fork is improved.
Preferably, the synchronizing shaft is provided with a limiting groove, a sliding sleeve is arranged in the limiting groove, and the shifting fork is arranged on the sliding sleeve. On one hand, the stability of the position of the shifting fork is ensured, namely the matching accuracy of the shifting fork and the tray slot is ensured; on the other hand, the friction force between the shifting fork and the synchronizing shaft is reduced, and the fluency of the shifting fork during action is improved.

The shaping mechanism does not need an independent driving device, and when the jacking bearing moves upwards, the linkage frame is jacked up, 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 to one side of the tray to shape the stacked tray.
Preferably, the mounting plate is provided with a limiting shaft, and the linkage frame is provided with an arc-shaped limiting groove matched with the limiting shaft to limit the rotation range of the linkage frame, so that the stability of the action range of the push rod is ensured, and interference on other components is avoided.

At least one guide chain wheel in each group of guide assemblies is a double-row chain wheel, and the two groups of guide assemblies are in transmission connection at the double-row chain wheel through a chain so as to ensure that the two groups of guide assemblies perform synchronous and equidirectional actions and drive a shifting fork to act together.
Wherein, two of them adjacent round pin axles on the direction chain are extension round pin axle 301, be equipped with two pinhole 302 on the direction connecting piece 3 to be fixed in two extension round pin axles 301 through link joint 303, connected mode simple structure, the dismouting is more convenient. And, the direction connecting piece 3 includes chain connecting block 31 and shift fork connecting plate 32 of adjacent connection, the thickness of chain connecting block 31 is greater than the thickness of shift fork connecting plate 32, shift fork connecting plate 31 and chain connecting block 32 are back to the side parallel and level of direction chain to there is enough distance between shift fork connecting plate and the direction chain, avoid taking place to interfere.
This chain formula shift fork guiding mechanism's theory of operation: it is known that to lift a pallet, the forks on opposite sides must be symmetrically operated at the same time, and for the sake of simplicity, the operation of the forks on one side will be described below as an example.
When disc stacking starts, the shifting fork is positioned at a position where the first translation section 21 is close to the first lifting section 23, firstly, the shifting fork moves to the second lifting section 24 along the first translation section 21, and along with the process, the shifting fork is inserted into a slot on the side surface of the first tray; then, the shifting fork ascends along the second lifting section 24 and lifts the first tray until reaching the highest point; at the moment, a second tray is conveyed from the lower part of the first tray by a chain machine and the like; then, the fork is lowered along the third lifting section 25, and the first pallet is lowered onto the second pallet; subsequently, the fork moves along the second translation section 22 to the first lifting section 23 to withdraw from the slot on the side of the first pallet; finally, the fork is lowered to the lowest point along the first elevation section 23. Then, the shifting fork repeats the actions, the second tray at the bottom is inserted in the second action, the two trays are lifted, and finally the lower parts of the two trays are conveyed to the third tray. And by parity of reasoning, the whole disc stacking work is completed.
When the tray is disassembled, the guide chain rotates reversely, the shifting fork is positioned at the highest point and supports a plurality of stacked trays; firstly, the shifting fork descends to the lowest point along the second lifting section 24, and at the moment, the upper tray of the shifting fork descends to a conveying platform such as a chain machine; then the shifting fork moves along the first translation section 21 to the first lifting section 23 to withdraw from the slot of the tray; then the shifting fork ascends to the second translation section 22 along the first lifting section 23 and then moves to the third lifting section 25 along the second translation section 22, and in the translation process, the shifting fork is inserted into a slot of a second tray at the lower end; the fork then rises to the highest point along the third lifting section 25 to lift the second tray at the lower end and all trays thereon together, so that the first tray at the lower end is located on the conveying table alone, and the conveying table can convey the first tray away, that is, the tray detaching operation of the first tray is completed. And by parity of reasoning, the whole disc disassembling work is completed.
It should be noted that, because the rotation connecting axis of the guide link 3 and the shifting fork is located inside the guide chain, and the distance between the rotation connecting axis of the guide link 3 and the shifting fork and the guide chain is equal to the distance between the rotation axis of the guide sprocket 1 and the guide chain. The guide connecting piece 3 can not rotate together with the shifting fork when passing through a corner, wherein the guide connecting piece 3 can independently rotate 90 degrees when passing through the joint of the second translation section 22 and the first lifting section 23, the joint of the first lifting section 23 and the first translation section 21 and the joint of the first translation section 21 and the second lifting section 24, and can independently rotate 180 degrees when passing through the joint of the second lifting section 24 and the third lifting section 25; in the process that the guide connecting piece 3 rotates independently, the shifting forks can be kept in the original positions, namely, the shifting forks only perform translation or lifting actions when passing through the plurality of connecting positions, so that the stability of the shifting forks is ensured; particularly, the joint of the second lifting section 24 and the third lifting section 25 is the highest point, the shifting fork is certain to hold the tray at the highest point, and if the shifting fork is translated (in the plugging and unplugging direction), potential safety hazards such as displacement of the tray and the like are caused by friction force between the shifting fork and the shifting fork. Of course, inevitably, at the junction of the second translation stage 22 and the third lifting stage 25, the guide link 3 cannot rotate at this point, i.e. the fork needs to follow the guide link 3 in a small arc-shaped movement, since the corner at this point is inward, i.e. the guide sprocket at this point is outside the guide chain, while the guide link 3 is inside the guide chain. However, the end of the process of inserting the shift fork into the tray slot, or the beginning of the process of withdrawing the shift fork from the tray slot, can be designed by the size, so that the shift fork does not contact with the upper and lower side walls of the tray slot in the arc motion process (the height of the slot is certainly much larger than the thickness of the shift fork). Therefore, only one place needs to be correspondingly dimensioned, and other four places do not need to be specially processed.
As shown in fig. 3-6, the invention also provides an unstacking and stacking tray machine, which comprises a supporting frame, a driving mechanism, the chain type shifting fork guide mechanism and the shifting fork 4. The supporting frame is mainly composed of four vertical columns 51 and a cross beam 52 arranged between the vertical columns 51. The driving mechanism is arranged at the lower part in the supporting frame and comprises a driving motor 61, a first transmission shaft 62 connected to the output end of the driving motor 61 in a transmission manner through a chain wheel and chain assembly, a second transmission shaft 63 connected to the first transmission shaft 62 in a transmission manner through gear meshing, and a transmission chain 64 connected to each transmission shaft through a chain wheel, wherein the two transmission shafts synchronously rotate in opposite directions due to the gear meshing transmission relationship. Moreover, both ends of each transmission shaft are provided with transmission chains 64, and each upright post 51 is provided with the chain type shifting fork guide mechanism, and correspondingly, each group of chain type shifting fork guide mechanisms is matched with one shifting fork 4, so that each transmission chain 64 drives one group of chain type shifting fork guide mechanisms and one shifting fork 4 to act respectively; the two groups of chain type shifting fork guide mechanisms on the same side are driven by the same transmission shaft to synchronously move in the same direction, and the chain type shifting fork guide mechanisms on the opposite side synchronously move in the opposite direction, so that the shifting forks on the two sides move in opposite directions to insert the tray or move back to withdraw the tray.
Specifically, in the chain type shifting fork guide mechanism, except that the guide chain wheels for driving the upper and lower guide assemblies are double-row chain wheels, a double-row chain wheel is required to be adopted in the rest guide chain wheels 1 for driving connection with the transmission chain 64. In addition, a direction changing sprocket 65 that engages with the transmission chain 64 is provided on the lower portion of the column 51 so that the transmission chain 64 can escape from a space on the lower portion of the support frame where conveying equipment such as a chain conveyor is installed.
In order to ensure the synchronism, the stability and the structural strength of the actions of the two shifting forks on the same side, a synchronizing shaft 7 is fixedly connected between the guide connecting pieces in the two groups of chain type shifting fork guide mechanisms on the same side of the supporting frame, and the shifting forks 4 are rotationally connected to the synchronizing shaft 7, namely, one shifting fork 4 is rotationally connected with the two synchronizing shafts 7 at the same time. And, synchronizing shaft 7 both ends all are equipped with the spacing groove, and the limiting groove is equipped with sliding sleeve 71, and shift fork 4 locates on sliding sleeve 71. The structure ensures the stability of the position of the shifting fork, namely the matching accuracy of the shifting fork and the tray slot; on the other hand, the friction force between the shifting fork and the synchronizing shaft is reduced, and the fluency of the shifting fork during action is improved.
In addition, the opposite side surfaces of the two columns 51 on the same side are also provided with a shaping mechanism, as shown in fig. 5, the shaping mechanism comprises an upper mounting plate 81, a lower mounting plate 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 linkage frame 82 and the lower linkage frame 82, the mounting plate below is positioned above the guide chain, the upper end of the shifting fork is provided with a jacking bearing 84 through a slot and a rotating shaft, when the shifting fork rises to the highest point, the jacking bearing 84 jacks the linkage frame 82 to a horizontal state, so that the push rod 83 is pushed out to the supporting frame for a certain distance, as shown in fig. 6, namely, the side edge of the tray 10 is extruded for a certain distance, and the four push rods 83 on the two sides of the tray are simultaneously extruded to the middle part, so as to shape the stacked tray. And, the shaping mechanism does not need independent drive arrangement, only relies on the drive of shift fork to realize the plastic action, and the cost is lower. In order to limit the swing range of the linkage frame 82 and avoid interference with other components, a limiting shaft 85 is arranged on the mounting plate 81, and an arc-shaped limiting groove 86 matched with the limiting shaft 85 is arranged on the linkage frame 82.
Finally, the use of the machine for opening and closing the trays generally requires the cooperation of conveying devices such as a chain machine 9, which passes through the supporting frame and has a conveying table above the driving mechanism to convey the trays 10 in sequence during the stacking and to convey them away in sequence during the opening of the trays.
