Description

AN AUTOMATIC MULTI-MATERIAL SAMPLE PRESS BACKGROUND OF THE INVENTION

[0001] 1. Technical Field

[0002] The present disclosure relates to a distribution and storage device, and

more specifically, to an automatic multi-material sample press, which belongs to the

technical field of metallurgical testing equipment.

[0003] 2. Description of Related Art

[0004] A series of preparation operations before testing, such as sample delivery,

quantification, sample preparation, and output, need to be done for sample testing in

metallurgy and other industries. For a long time, such operations have been done with the

help of independent units, and the transfer between them relies on manpower, which is not

only inefficient and poor in safety, but also affect the accuracy of testing results.

[0005] The Chinese patent application with an application No. of 201810906838.5

discloses an automatic testing system for metallurgical samples. It comprises a set of air

conveyance receiving cabinets connected with each device in the sampling field

respectively through conveying channels, wherein the air conveyance receiving cabinets

are arranged in a circular arc, the center of the circular arc is provided with a first

manipulator, one side of the which being farthest from the air conveyance receiving

cabinet set, is provided with a grinding and pelletizing integrated machine, and a sample

placement table is arranged between one end of the air conveyance receiving cabinet set

and the adjacent end of the grinding and pelletizing integrated machine, thus forming a

C-shaped layout semi-enclosing the first manipulator; a second manipulator and a

packaging device beside the second manipulator are arranged on the side of the grinding

and pelletizing integrated machine away from the first transposition manipulator, and a

detection instrument is arranged on the side of the second transposition manipulator away from the grinding and pelletizing integrated machine.

[0006] Although the technical solution realizes the automation of the whole

process from sample preparation to obtaining of testing results, with a significantly

improved efficiency compared with the previous ones, and an ensured accuracy of the

testing result, its practice shows the following obvious defects of the technical solution: 1)

It relies on robots to complete the switching between the units of equipment, which not

only occupies a large area but also is not convenient for equipment maintenance and

debugging; 2) It can only be applied to a single variety of samples, with poor adaptability.

[0007] It is against this background and the problems and difficulties associated

therewith that the present invention has been developed.

BRIEF SUMMARY OF THE INVENTION

[0008] In one aspect there is provided an automatic multi-material sample press

comprising a sample cup conveying assembly and a sample output conveying assembly

which is arranged on one side of a workbench, a turntable assembly which is arranged in

the center of the workbench, and a pelletizing assembly, a ring grabbing assembly and a

liftable filler feeding assembly which surround the turntable assembly;

the turntable assembly is provided with a rotating tower driven by a vertical rotating

shaft, and at least one quantitative distribution device and a sample output suction cup

which can rotate up and down around a horizontal shaft are arranged on the periphery of

the rotating tower; the quantitative distribution device comprises a feeding funnel

matching a sample cup and a leakage hole capable of opening and closing quantitative

discharging control, and has a feeding station with the feeding funnel below it and a

distribution station with the leakage hole below it;

the sample cup conveying assembly comprises a sample cup lifting device which can reciprocate along the length direction; The sample cup lifting device has a lifting station which is below the quantitative distribution device and aligned with the feeding funnel when reaching the inner end in the length direction; the ring grabbing assembly comprises a sample ring air claw installed at the cantilever end of the vertical shaft rotating arm, and the sample ring air claw has a ring release station after the ring is taken; the pelletizing assembly comprises an upper pressing head and a lower pressing head which can move relative to each other and also comprises a swing arm installed with a sample holder at the extending end. The swingarm has a ring receiving station for positioning the sample holder below the ring release station of the sample ring air claw, a material receiving station below the distribution station and a pelletizing station between the upper pressing head and the lower pressing head; and the filler feeding assembly is positioned below the distribution station. The sample output suction cup has a sample taking station where the suction cup is above the pelletizing station and a sample output station located at the inner end of the sample output conveying assembly.

[0009] In this way, as long as the sequence of actions of each assembly is

coordinated, the following actions can be realized:

When the rotating tower drives the quantitative distribution device to turn to the

feeding station, the rotation up and down of the horizontal shaft of the device makes the

feeding funnel below; then, the sample cup lifting device of the sample cup conveying

assembly sends the sample cup to below the quantitative distribution device and aligns it

with the feeding funnel, and then jacks up and inserts the sample cup into the feeding

funnel;

The rotating tower rotates again to make the quantitative distribution device rotate to

the distribution station, and at the same time, the horizontal shaft of the device rotates up and down to make the leakage hole below; the swing arm of the pelletizing assembly rotates to the ring receiving station to receive the sample ring grabbed by the ring grabbing assembly, and then rotates to the material receiving station below the distribution station; the filler feeding assembly rises to make the sample ring fit the leakage hole; and the leakage hole is opened in a controlled manner to perform quantitative discharging;

After receiving the material, the swing arm of the pelletizing assembly rotates to the

pelletizing station between the upper and lower pressing heads. Once the upper and lower

pressing heads separate after closing and pelletizing, the sample output suction cup on the

rotating tower assembly rotates to the sample taking station and sucks up the sample ring

pressed, and reaches the sample output station at the inner end of the sample output

conveying assembly after the rotating tower rotates again so that the sample ring pressed

falls on the sample output conveying assembly for output.

[0010] In one aspect, not only all units of the equipment are integrated, occupying

a small area and facilitating maintenance and debugging, but rapid switching is made

possible, which is beneficial to ensuring the state of samples and creating good conditions

for the subsequent testing and inspection; in addition, the rotating tower provides

convenience for setting multiple quantitative distribution devices as needed, so that the

equipment has ideal adaptability, and can automatically complete the preparation

operation before the testing of multiple kinds of samples and multiple continuous samples.

[0011] In one form, the press further comprises a ring-lifting assembly which can

jack the sample ring out of the ring cylinder to a ring supply station, and the ring supply

station is located on the turning radius of the rotating arm of the ring grabbing assembly;

the sample ring air claw of the ring grabbing assembly has a ring taking station

corresponding to the ring supply station. Therefore, as long as the whole stack of sample

rings is put into the ring cylinder, the rings can be supplied one by one as needed, so as to

facilitate subsequent automatic operation and further improve the automation degree.

[0012] In one form, the press further comprises a purging assembly and a dust

removal assembly, and the quantitative distribution device also has a cleaning station with

a leakage hole above it and a feeding funnel below it; the purging assembly has a liftable

purging downward opening above the leakage hole; and the dust removal assembly has a

liftable dust suction pipe below the feeding funnel. Therefore, after quantitative

distribution, the sample cup and sample ring can be taken away, the purging downward

opening can be lowered, the dust suction pipe can be raised, and the leakage hole can be

opened to automatically clean the quantitative distribution device by simultaneously

purging the leakage hole and sucking dust from the feeding funnel, thus laying a good

foundation for the subsequent work.

[0013] In one form, the press further comprises a wiping assembly, and the swing

arm of the pelletizing assembly also has a wiping station below the wiping assembly. In

this way, the sample holder can be wiped automatically when needed.

DETAILED DESCRIPTION OF THE INVENTION

[0031] Embodiment I

The basic structure of the automatic multi-material sample press of this embodiment

is shown in FIG. 1, FIG. 2-1 and FIG. 2-2. One side of the workbench 1 is provided with a

sample cup conveying assembly 7 and a sample output conveying assembly 9 which are

parallel to each other, and are used for connecting with the robot which transfers the

sample cup containing the sample to be tested and the sample ring pressed. After lifting

the upper cover 1-1 of the workbench, you can see that the center of the workbench 1 is

provided with a turntable assembly 2, as well as a pelletizing assembly 3, a wiping

assembly 5, a ring-lifting assembly 4, a ring grabbing assembly 6, a purging assembly 10,

a dust removal assembly 11 and a liftable filler feeding assembly 8 which surround the

turntable assembly 2.

[0032] The specific structure of the turntable assembly 2 is shown in FIG. 3. The

tower bottom 2-1 fixed on the workbench 1 is provided with an octagonal rotating tower

2-4 driven by a vertical rotating shaft driven by a rotating tower motor 2-6. Four

quantitative distribution devices 2-5 which can be rotated up and down around a

horizontal axis are evenly distributed around the periphery of the rotating tower, and a

sample output suction cup 2-2 located at the lower end of a lifting cylinder 2-3 at the front

end of the extension arm is also installed between the two quantitative distribution devices.

The sample output suction cup 2-2 is controlled by the transposition of the rotating tower

and has a sample taking station where the suction cup is located above the pelletizing

station and a sample output station located at the inner end of the sample output conveying

assembly 9.

[0033] Although we can refer to the prior art publications such as the raw material

quantitative distribution device with the application number of CN01267187.8, the

logistics line quantitative distribution device with the application number of

CN201821730061.3, and the granular product packaging quantitative distribution

mechanism with the application number of CN201720785052.3 for the quantitative

distribution device, the quantitative distribution device 2-5 of the powder sample in this

embodiment is an innovative structure of those shown in FIG. 3-1 and FIG. 2-2, including

the shell D-5 which is driven by a rotating cylinder D-8 to rotate around a horizontal axis.

The rotating cylinder D-8 is installed on the rotating tower 2-4, one side of the shell D-5 is

installed with a pneumatic vibration device D-2 (commonly known as air hammer), and

within its vertical central hole D-5-1 is provided with a feeding funnel D-1 to form a

vertical moving pair with the shell. The inner wall of the feeding funnel D-1 is mirror

polished. The upper inner diameter of the feeding funnel D-1 is adapted to the outer

diameter of the material cup D-6, so as to seal the inserted material cup D-6. Two outer

sides are respectively provided with cup clamping cylinders D-7, and the horizontal

telescopic ends of the cup clamping cylinders D-7 are provided with inner plugs D-7-1

adapted to the positioning grooves of the material cup D-6 so that the inserted material cup

D-6 can be pneumatically positioned and clamped reliably. The lower end of the central

hole D-5-1 of the feeding funnel D-1 is tapered to form a funnel mouth, which is provided

with a cross rib D-1-1, and the center of the cross rib D-1-1 is provided with a valve stem

D-4 extending downwards. The lower part of the shell D-5 is provided with a pair of

lifting cylinders D-3, and the upper ends of the lifting pistons D-3-1 of the lifting cylinders

D-3 are fixedly connected with the excircle at the lower tapered part of the central hole

D-5-1 of the feeding funnel D-1 through an upper seat plate D-9. The lower end of the

shell D-5 is provided with a quantitation head D-11 with a transition arc to form a tapered

leakage hole D-11-1. The lower end of the valve stem D-4 is in the shape of an expanding

frustum, which is adapted to the leakage hole D-11-1, with its maximum outer diameter

smaller than the maximum inner diameter of the leakage hole D-11-1, so that the leakage

hole D-11-1 can be blocked when descending as shown in FIG. 3-2.

[0034] The central hole D-5-1 of the feeding funnel D-1 is hermetically connected

with the quantitation head D-11 through the elastic silicone tube D-10, and the connection

is reinforced by fasteners such as hoops to form a flexible connection channel.

[0035] During operation, the rotating cylinder drives the shell to the feeding

station with the feeding funnel at the bottom and the quantitation head at the top. After

inserting the cup containing samples from bottom to top, the cup clamping cylinder acts to

clamp the cup. Then, the rotating cylinder is used again to drive the shell to the

distribution station with the feeding funnel at the top and the quantitation head at the

bottom. After placing a material receiving test device such as a sample ring below it, start

the lifting cylinders. When the lifting piston is in the raised position, the valve stem is

lifted to open the leakage hole, and the quantitation head is opened to discharge materials.

When the discharge amount reaches a preset amount, the lifting cylinders fall in time, the

valve stem of the lifting piston is in a lowered position to close the leakage hole, and the

quantitation head is closed. Finally, the rotating cylinder drives the shell again to make the

feeding funnel face down and the quantitation head faces up, and the excess powder

returns to the material cup. When the cup clamping cylinder is released, the material cup

can be removed from the quantitative distribution device, and the filled sample ring can be

sent to press the sample. With the help of a flexible channel structure and the lifting

control of lifting cylinders, quantitative sample distribution can be realized conveniently

and reliably, ensuring sealing, no material leakage, and no pollution; besides, after one

quantitative sample distribution, redundant samples can be directly returned to the

material cup, so that the same sample can be quantitatively distributed for multiple times,

thus realizing the integrated design of quantitative acquisition and residual material return.

[0036] The specific structure of the sample cup conveying assembly 7 is shown in

FIG. 4. The cantilever cup feeding rail 7-3 is supported on the chassis 7-1. The sample cup

lifting device capable of reciprocating along the length direction includes a cup feeding block 7-4 with a sample cup table 7-5 installed at the top. The cup feeding block 7-4 can not only be driven to move along the cup feeding rail 7-3 but also jack up the cup under the action of the cup jacking cylinder 7-2. When the sample cup lifting device reaches the inner end in the length direction of the cup feeding rail 7-3, it is located at the lifting station below the quantitative distribution device 2-5 and aligned with the feeding funnel

D-1. At this time, the cup jacking cylinder 7-2 can jack up the sample cup containing the

sample from bottom to top and insert it into the feeding funnel D-1. Moreover, the sample

cup conveying assembly 7 can also convey the cut in the opposite direction as needed,

return and output the sample cup containing excess samples which are then transferred by

the robot for temporary storage.

[0037] The structure of the ring grabbing assembly 6 is shown in FIG. 5. The upper

end of the vertical shaft 6-2 of the bottom rotating cylinder 6-1 is connected with a

rotating arm 6-3, and the cantilever end of the rotating arm 6-3 is provided with a

downward sample ring air claw 6-5 (DHDS-32-A purchased from Germany FESTO)

which has a ring taking station and a ring release station on the same arc.

[0038] The pelletizing assembly 3 can be of the prior art structures such as the

laboratory grinding and pelletizing integrated machine with the application number of

CN201720137476.9, a multi-functional laboratory slag sample preparation, and pelletizing

device and an integrated machine with the application number of CN201710013812.3. In

this embodiment, as shown in FIG. 6, the lower part of the base 3-8 of the pelletizing

assembly 3 is provided with a lower pressing head 3-7, and the upper part is provided with

an upper pressing head 3-1 located at the lower end of the downward pressing cylinder 3-3.

Under the driving action of the downward pressing cylinder 3-3, the upper pressing head

3-1 can move downward relative to the lower pressing head 3-7, and a dust suction nozzle

3-2 is installed above the lower pressing head 3-7, which can suck away the dust

overflowing during sample pressing. In addition, one side of the upper part of the base 3-8 is also hinged with a swing arm 3-5 through a vertical electric rotating shaft 3-4, and the extending end of the swing arm is installed with a sample holder 3-6 for positioning the sample ring. Driven by the electric rotating shaft 3-4, the swing arm 3-5 can be switched as needed among the ring receiving station (see FIG. 13) where the sample holder 3-6 is at the ring release station of the sample ring air claw, the material receiving station (see FIG.

14) below the distribution station of the quantitative distribution device, the pelletizing

station (see FIG. 15) between the upper pressing head and the lower pressing head, and the

wiping station (see FIG. 16).

[0039] As shown in FIG. 7, the filler feeding assembly 8 includes a liftable ring

holder 8-1 which is installed under the distribution station of the quantitative distribution

device through a frame body 8-2. The ring holder 8-1 is driven by a holder cylinder 8-3 so

that it can hold up and press the sample ring against the leakage hole after a sample ring is

placed under the leakage hole of the quantitative device, thus avoiding material leakage.

After the quantitation head is opened for discharging, the ring holder 8-1 is lowered so as

to remove the sample ring.

[0040] As shown in FIG. 8, the sample output conveying assembly 9 has a

cantilever sample output rail 9-2 supported on a strut 9-1, and the upper surface of the

sample output rail 9-2 bears a sample supporting slide block 9-3. Because the sample

output suction cup has a sample taking station where the suction cup is located above the

pelletizing station and a sample output station located at the inner end of the sample output

conveying assembly, the pressed sample ring can be transferred to the sample output

conveying assembly 9, and then transferred to the robot by the sample output conveying

assembly 9.

[0041] The function of the ring-lifting assembly 4 is to jack out a group of sample

rings one by one, which is convenient for the ring grabbing assembly 6 to grab. Its

structure is shown in FIG. 9: A ring transferring platform 4-3 is installed on the bottom support 4-4, one end of the ring transferring platform 4-3 is provided with a ring cylinder

4-2 for placing a whole stack of sample rings 4-1 and the other end is provided with a ring

outlet 4-5, and the lower part of the ring outlet 4-5 is provided with a ring-jacking cylinder.

Because the ring-lifting assembly 4 is located on the turning radius of the rotating arm of

the ring grabbing assembly 6, determining the ring supply station, and the sample ring air

claw of the ring grabbing assembly has a ring taking station corresponding to the ring

supply station. Therefore, as long as the whole stack of sample rings is put into the ring

cylinder, the sample rings can be sent out from the ring outlet to be grabbed as needed, and

subsequent operations can be automatically carried out.

[0042] The purging assembly 10 and the dust removal assembly 11 are arranged in

pairs respectively above and below the cleaning station of the quantitative distribution

device with a leakage hole above it and a feeding funnel below it. As shown in FIG. 10,

the purging assembly 10 has a liftable purging downward opening 10-2 located above the

leakage hole, and the purging downward opening 10-2 is arranged at one end of the lifting

device 10-1 so that it can be lowered to the leakage hole at the upper position as needed.

The dust removal assembly 11 has a dust suction pipe 11-2 located below the feeding

funnel, and the dust suction pipe 11-2 is fixed on the liftable slide block 11-1 so that after

the quantitative distribution is completed and the sample cup and sample ring are taken

away, the purging downward opening can be lowered, the dust suction pipe can be raised,

the leakage hole can be opened, to automatically clean the quantitative distribution device

by purging and sucking.

[0043] The wiping assembly 5 can be of the prior art such as the board surface

wiping device with the application number of CN 201910384053.0, or as shown in FIG.

12, arranged corresponding to the wiping station of the swing arm of the pelletizing

assembly, and the upper part of its mounting plate C-1 is provided with a driven reel C-3

for placing the dust-free paper roll C-2, and the driven reel C-3 is provided with a retaining piece C-3-1 through a locking device C-3-2, so as to prevent the deviation of the paper tape. An inverted pyramid winding wheelset is installed below the driven reel C-3, in which the upper left and right rubber-covered rollers with bearings C-4 and C-5 are tangent to the lower polyurethane pressing roller C-6 respectively. A wiping unit C-7 is installed below the winding wheelset through a lifting cylinder C-7-1 located at the rear side of the mounting plate C-1. The wiping unit C-7 consists of a flat-bottomed wiping block C-7-2 and guide rods C-8 located on the two sides of the wiping block. The wiping block C-7-2 and the mounting plate C-1 form a vertical moving pair, which can be lifted as needed under the driving of the cylinder. A driving reel C-9 is installed near one side of the wiping unit C-7. The mounting plate C-1 is also provided with a meter counter C-10, and the sensing wheel of the meter counter C-10 is tangent to the steering rod C-11 installed on the winding path. When in use, the sample holder to be wiped moves to below the wiping assembly, the wiping block is driven to descend to fit the sample holder, and the motor drives the driving reel to pull out the dust-free cloth for wiping, and until the meter counter detects that the pull-out length of the paper tape reaches the set value, a stop signal is sent to stop the motor, thus ending the automatic wiping of the sample holder.

[0044] The automatic sample pressing process of the automatic multi-material

sample press in this embodiment is as follows: 1) Put the sample cup on the sample cup

conveying assembly and input the sample cup type of the material to be tested to the

control system of the sample press; 2) When the control system determines the

quantitative distribution device corresponding to the material and controls the rotating

tower to drive the quantitative distribution device to the feeding station, the horizontal axis

of the quantitative distribution device is rotated up and down to make the feeding funnel

below; then, the sample cup lifting device of the sample cup conveying assembly sends

the sample cup to below the quantitative distribution device and aligns it with the feeding

funnel, and then jacks up and inserts the sample cup into the feeding funnel; 3) the rotating tower rotates again to rotate the quantitative distribution device to the distribution station, and at the same time, the horizontal shaft of the quantitative distribution device rotates up and down to make the leakage hole below; the ring-lifting assembly jacks the sample ring out of the ring cylinder to the ring supply station, and the sample ring air claw of the ring grabbing assembly transfers the sample ring from the ring supply station to the ring taking station; the swing arm of the pelletizing assembly rotates to the ring receiving station to receive the sample ring grabbed by the ring grabbing assembly, and then rotates to the material receiving station below the distribution station; the filler feeding assembly rises to make the sample ring fit the leakage hole; and the leakage hole is opened in a controlled manner to perform quantitative discharging; 4) After receiving the material, the swing arm of the pelletizing assembly rotates to the pelletizing station between the upper and lower pressing heads. Once the upper and lower pressing heads separate after closing and pelletizing, the sample output suction cup on the rotating tower assembly rotates to the sample taking station and sucks up the sample ring pressed, and reaches the sample output station at the inner end of the sample output conveying assembly after the rotating tower rotates again so that the sample ring pressed falls on the sample output conveying assembly for output; 5) After the sample preparation is completed, the sample cup is output along the original path, and taken away by the robot or manually; 6) Finally, the quantitative distribution device is purged and cleaned at the cleaning station, and the sample holder of the pelletizing assembly is wiped and cleaned at the wiping station.

[0045] When this embodiment is adopted, continuous input of multiple sample

cups and continuous input of various kinds of materials can be tailor-made according to

the above process and actual production requirements, thus meeting the requirements of

all actual process flows.

[0046] Experiments show that this embodiment has the following obvious

advantages: 1) Automatic integrated operation, and less dependence on robots, which avoids the influence of human factors on testing results; 2) A specific quantitation assembly is selected for samples of the same kind. After sample preparation, there are multiple cleaning methods such as scraping, wiping, purging and vacuum suction, which effectively avoids cross-contamination between samples and ensures the accuracy of testing results; 3) It can automatically complete all preparations before the testing of multiple kinds of samples and multiple continuous samples, with ideal adaptability.

[0047] In addition to the embodiments above, the present invention can have other

embodiments. Any technical solution formed by equivalent substitution or equivalent

transformation falls within the protection scope claimed by the present invention.

[0048] Advantageously, the present disclosure provides an automatic

multi-material sample press that can automatically complete the whole process from

sample feeding, quantification, sample preparation to sample output, to efficiently,

accurately, and safely complete the preparations before testing of metallurgical test

samples.
