For example, when mobile phone screen glass is processed, vertical and horizontal clamping of a plurality of pieces of glass can often be accomplished simultaneously to some stations, also often through the simultaneous operation of a plurality of cutters in the processing procedure. After the materials are transported to the current station by the conveyor belt, the materials processed by the current process are manually unloaded from the conveyor belt by a worker or by means of an instrument and then stacked at the detention position, which wastes time and labor.

Therefore, how to reduce the occupation of the installation area of the factory building on the basis of improving the material transportation efficiency and meet the requirements of a specific station on vertical concentrated feeding and process treatment is a technical problem faced by technical personnel in the field.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic overall structure diagram of an embodiment of the present invention, and fig. 2 is a front view of fig. 1.

The utility model provides an among the specific embodiment, range upon range of lift feedway mainly includes mounting plate 1, bearing mechanism 2, climbing mechanism 3 and actuating mechanism 4.

The mounting base plate 1 is generally fixed on a factory floor or a machine tool body and other structures, and is mainly used for mounting and bearing other parts. Supporting mechanism 2 sets up on mounting plate 1's surface, and mainly used is in current high position with material tray 0 bearing. Climbing mechanism 3 also sets up on mounting plate 1 to vertical elevating movement can carry out on mounting plate 1, mainly used bearing material tray 0 or take the synchronous lift of animal material tray 0 to predetermine the height in elevating movement. The driving mechanism 4 is arranged on the mounting bottom plate 1 and is mainly used for driving the jacking mechanism 3 to perform reciprocating lifting motion.

Importantly, both the supporting mechanism 2 and the jacking mechanism 3 have double-station states, when the supporting mechanism and the jacking mechanism are in the first station state, both keep supporting the material tray 0, and when the supporting mechanism and the jacking mechanism are in the second station state, both break away from supporting the material tray 0. So, through bearing mechanism 2 and the switching and the cooperation of climbing mechanism 3 between two station states, can realize the vertical lift feed of material tray 0.

Taking vertical lifting feeding as an example, when a material tray 0 enters the equipment from a previous station, the material tray can firstly enter the jacking mechanism 3, and at the moment, the jacking mechanism 3 is in a first station state and stably supports the material tray 0; then, the driving mechanism 4 drives the jacking mechanism 3 to ascend by a preset height and then stops, at the moment, the supporting mechanism 2 is switched from the second station state to the first station state, and the material tray 0 ascending by the preset height is supported; next, the jacking mechanism 3 is switched from the first station state to the second station state, and the material tray 0 is not supported, but the material tray 0 is supported by the supporting mechanism 2 at the same time, so that the material tray 0 is kept unchanged at the current height position; next, the driving mechanism 4 drives the jacking mechanism 3 to descend by a preset height (such as resetting), then the jacking mechanism 3 is switched to the first station state again, and the bearing of the material tray 0 is maintained again — note that the position of the jacking mechanism 3 for bearing the material tray 0 is different from the previous time, and the difference is that the preset height is increased; finally, bearing mechanism 2 switches to the second station state, loosens material tray 0, only carries out the bearing by climbing mechanism 3, and later actuating mechanism 4 drives climbing mechanism 3 again and rises to it presets the height to lift material tray 0 once more. So, after the above-mentioned operation of many times reciprocating cycle, can lift material tray 0 to the top from the bottom one by one, realize the vertical feeding that lifts.

For vertical descent feeding, the principle is similar to that of vertical elevation feeding, and the description is omitted here. And can support polylith material tray 0 simultaneously on supporting mechanism 2 and climbing mechanism 3, consequently can realize the range upon range of continuous vertical feed of material tray 0.

To sum up, the range upon range of lift feeding equipment that this embodiment provided can reduce the occupation to factory building installation area on the basis of improving material transport efficiency, satisfies the demand that specific station was handled to vertical concentrated feeding and technology simultaneously.

In a preferred embodiment with respect to the holding means 2, the holding means 2 essentially comprises a plurality of holding rods 201 and a plurality of holding plates 202. As shown in fig. 3, fig. 3 is a schematic structural diagram of the support rod (or the lifting rod) shown in fig. 1. Wherein, each support rod 201 is rotatably erected on the surface of the mounting baseplate 1, each support plate 202 is horizontally inserted on the circumferential surface of each support rod 201, and each support plate 202 is uniformly distributed in the axial direction (vertical direction) of each support rod 201. Each support plate 202 is mainly used to support the material tray 0 when the support mechanism 2 is in the first station state, so that the material tray 0 is kept at the current height position. Specifically, when each of the support rods 201 rotates to the first target angle, each of the support plates 202 rotates synchronously therewith to a position located on the bottom surface of the material tray 0, thereby stably supporting the material tray 0. When each support rod 201 rotates to a second target angle, each support plate 202 rotates synchronously with the support rod and rotates to a position separated from the bottom surface of the material tray 0, so that the support rod is separated from the material tray 0.

In order to conveniently realize the rotation motion of each support rod 201, a rotating component with higher precision such as a stepping motor can be adopted, and the rotation of the output end of the stepping motor drives each support rod 201 to rotate.

In one embodiment, the rotation angle of each supporting rod 201 may be 0 to 90 °, and the specific angle range may be divided into four quadrants based on the surface of the mounting base plate 1. When each supporting rod 201 rotates to an angular position of 0 degree, each supporting plate 202 can transversely extend into the bottom surface of the material tray 0 at the moment, and the supporting mechanism 2 is in a first station state; when each support rod 201 rotates to 90 ° angular orientation, each support plate 202 can be arranged at its two sides (depending on the rotation direction of the support rod 201) along the length direction or width direction of the material tray 0, and the support mechanism 2 is in the second station state.

Consider that material tray 0 generally is the rectangle, and its length dimension is obvious, for the bearing stability of improvement to material tray 0, in this embodiment, each bearing rod 201 can be located material tray 0's front and back both ends position respectively to divide simultaneously and arrange in material tray 0's left and right sides position. So set up, each bearing board 202 on each bearing rod 201 can conveniently rotate to the bottom surface butt with material tray 0, avoids material tray 0 to produce skew or upset moment under the action of gravity simultaneously, guarantees that material tray 0 is in horizontal bearing state.

Further, for improving the stacked feeding efficiency and avoiding the waste of vertical space, in this embodiment, not only the plurality of supporting plates 202 are uniformly arranged along the axial direction (vertical direction) of the supporting rod 201, but also the vertical distance between any two adjacent supporting plates 202 in the vertical direction is designed to be equal to the thickness of a single material tray 0. So set up, material tray 0 just can be put down in the space between two adjacent bearing board 202, when carrying out the feed, can be full of material tray 0 with whole range upon range of lift feeding equipment's vertical installation space to range upon range of feed is constantly realized utilizing the maximize in vertical space. Of course, for some lighter and thinner material trays 0, several material trays 0 may be put down between two adjacent supporting plates 202 at the same time.

In a preferred embodiment of the jacking mechanism 3, the jacking mechanism 3 is similar to the supporting mechanism 2 in structure, and mainly comprises a plurality of jacking rods 301 and a plurality of jacking plates 302, as shown in fig. 3. Wherein the lifting rod 301 is rotatably provided on the mounting base plate 1 and can also perform a lifting motion at the same time. The respective lifting plates 302 are uniformly distributed along the axial direction (vertical direction) of the respective lifting rods 301, and are horizontally inserted on the circumferential surface of the respective lifting rods 301. The lifting rods 301 and the lifting plates 302 have the same functions as the supporting rods 201 and the supporting plates 202, namely, are used for supporting the material tray 0, but the different functions are that the lifting rods 301 and the lifting plates 302 can drive the material tray 0 to perform lifting movement while supporting the material tray.

Similar to the prop rod 201, the pivoting movement of the lift rod 301 changes the position of the lift mechanism 3. Specifically, when each lifting rod 301 rotates to a first target angle, each lifting plate 302 is located on the bottom surface of the material tray 0, and can support the material tray 0, and when each lifting rod 301 rotates to a second target angle, each lifting plate 302 is separated from the bottom surface of the material tray 0, and does not support the material tray 0 temporarily. Here, the rotation angle of the lifting rod 301 may be preferably 0 to 90 °, and may be the same as the rotation angle and the rotation orientation of the supporting rod 201. When each lifting rod 301 rotates to the angular position of 0 degree, each lifting plate 302 extends into the bottom surface of the material tray 0, at this time, the lifting mechanism 3 is in the first station state, and when each lifting rod 301 rotates to the angular position of 90 degrees, each lifting plate 302 is respectively positioned outside two sides of the material tray 0, at this time, the lifting mechanism 3 is in the second station state.

In order to conveniently realize the rotation of each jacking rod 301, a rotating component with higher precision such as a stepping motor can be adopted, and the rotation of the output end of the stepping motor drives each jacking rod 301 to rotate.

Similarly, in order to improve the bearing stability of the jacking mechanism 3 to the material tray 0, the distribution form of each jacking rod 301 on the mounting base plate 1 may be the same as that of each bearing rod 201, i.e., the jacking rods are respectively arranged at the front and rear ends of the material tray 0, and are respectively located at the left and right sides of the material tray 0. Consider that material tray 0 distributes simultaneously around has lifting rod 301 and bearing rod 201, for reducing the space and occupy, improve the structure standardization, adjacent lifting rod 301 can distribute with bearing rod 201 side by side. Here, preferably, considering that the material tray 0 is generally rectangular, the number of the supporting rods 201 and the lifting rods 301 distributed on the installation bottom plate 1 may be 4-8, and the supporting rods and the lifting rods are distributed in a rectangular shape. Of course, if the material tray 0 is circular, the supporting rods 201 and the lifting rods 301 may be distributed in a circular shape, and the number of the supporting rods 201 and the lifting rods 301 may be increased or decreased according to actual needs.

Moreover, considering that each supporting plate 202 and each lifting plate 302 need to continuously abut against and rub the bottom surface of the material tray 0 in the long-term operation process, the abrasion is large, and for facilitating periodic maintenance or replacement, the connecting plate 7 is detachably arranged on the circumferential side surface of each supporting rod 201 and each lifting rod 301, and each supporting plate 202 and each lifting plate 302 are connected to the side of the connecting plate 7. Specifically, the connecting plate 7 can be detachably connected to each supporting rod 201 and each lifting rod 301 through a fastener or a clamping structure, and each supporting plate 202 and each lifting plate 302 can be vertically connected to the side edge of the connecting plate 7.

In addition, in order to facilitate the driving mechanism 4 to drive a plurality of lifting rods 301 to perform lifting movement at the same time, a lifting bottom plate 5 is connected to the output end of the driving mechanism 4 in the embodiment, and each lifting rod 301 is disposed on the surface of the lifting bottom plate 5. Thus, the driving mechanism 4 can drive all the lifting rods 301 to perform synchronous lifting motion by lifting and driving the lifting bottom plate 5, thereby ensuring the motion synchronism of the lifting rods 301.

Further, consider still to be provided with the bearing pole 201 that need not elevating movement on the mounting plate 1, for preventing 5 and the bearing pole 201 of lifting plate from interfering each other, in this embodiment, can put actuating mechanism 4's output down, arrange the bottom of mounting plate 1 in promptly, thereby make 5 the position of lifting plate in the below of mounting plate 1, and leave between mounting plate 1 and the lifting plate 5 and predetermine the clearance, should predetermine the specific numerical value in clearance indefinite, can adjust according to actual conditions, mainly used supplies 5 the lifting plate to carry out vertical lift under actuating mechanism 4's drive. So, each jacking rod 301 just sets up in mounting plate 1's bottom to need pass mounting plate 1, for this reason, seted up a plurality of guiding hole 101 on mounting plate 1, can supply each jacking rod 301 to go up and down current, retrain its circumferential direction's motion simultaneously, provide vertical guide effect. Of course, the output end of the driving mechanism 4 may be disposed on the top, and the lifting bottom plate 5 may be disposed above the mounting bottom plate 1, but at this time, a through hole for the support rod 201 to pass through needs to be formed in the lifting bottom plate 5.

Furthermore, in order to enhance the connection between the installation base plate 1 and the lifting base plate 5, a plurality of telescopic rods 6 are connected between the bottom surface of the installation base plate 1 and the surface of the lifting base plate 5. So set up, when actuating mechanism 4 drives lifting bottom plate 5 and carries out elevating movement, each telescopic link 6 will stretch out and draw back in step, has not only improved the motion ride comfort, has still improved structural strength between them.

In an embodiment of the driving mechanism 4, the driving mechanism 4 may be a power component such as a hydraulic cylinder, and the lifting motion of each lifting rod 301 is realized by the extension and contraction motion of a piston rod.
