Description

Continuous feeder and metal printing coater for thin plates

Technical Field

The invention belongs to the technical field of printing equipment, and particularly relates to a continuous sheet feeder which can be used for feeding front ends of sheet metal printers, metal printing coaters, high-speed metal printing machines and the like.

Background

The tin printing is to print on iron sheet, which belongs to the category of special printing-metal printing, and the printing material is mainly tin plate (tinplate), tin-free plate, aluminum plate, etc. The metal printing products have the advantages of bright color, rich layers, good processing manufacturability of printing materials, diversity of modeling designs and the like, are favored by the market, and the iron printing equipment is rapidly developed. The metal printing is widely applied to the printing of various daily necessities such as containers, covers, building materials, household electrical appliances, furniture, labels and the like, wherein the printing speed of an iron printing device such as a stacked Zhang Shigao quick iron printing coater (such as KBA, gaobao and the like) is 80-120 sheets/min, and when in printing, the printed iron skin material on the lifting material platform is orderly separated one by the Feida, and the printed iron skin material is input into the iron printing coater to finish the printing work.

After the iron sheet on the lifting material table of the flying device is separated, the material conveying is generally required to be interrupted temporarily, then the manual material feeding is adopted, and then the material conveying button is started to continuously convey the material for printing and coating. However, the time taken to switch the material stack is long, resulting in lower production efficiency; meanwhile, the ink color of a printed product is influenced after stopping every time during printing, so that the quality of the product is difficult to ensure, and the rejection rate is correspondingly high; in addition, the drying room and the like do not stop and work normally in the time of changing the iron sheet to stop conveying, so that energy loss is caused.

From this technology, for example, chinese patent document CN101624145a discloses a continuous feeding system, which adopts a fork to hold a wooden plate, and after the next stack of iron sheets enters, the fork holds the wooden plate to automatically retract, but the time required for the fork to withdraw and the next stack of iron sheets to enter is still long (generally 1.5 minutes), especially when the tin printing coater is produced at high speed, so that the production efficiency is further affected.

To further solve the above problems, at least the following disclosures exist in the past:

1) The iron sheet is supported by two sides of the lifting material table, then the material pushing support plate descends to support another material pile iron sheet and ascends to a set position or other modes, for example, the structure is disclosed in Chinese patent document CN104191810A, CN203995073U, CN202214029U, CN107738945A, US 5011126A; because the weight of the iron sheet is large, the supporting rod is easy to scratch, scratch and scratch on the surface of the iron sheet under the action of gravity, and the printing quality of the iron sheet is affected;

2) A double feed switching method, for example, chinese patent document CN106241330a and CN106185250a; the structure is complex, and the occupied space is large;

3) The sheet iron is supported by one side of the feeding direction, and then the material pushing support plate descends to receive another material pile sheet iron and ascends to a set position or other modes, for example, chinese patent document CN204488205U.

By analyzing the above patent, in chinese patent document CN204488205U, the continuous feeding device mainly comprises a carriage forward and backward moving structure and a pallet lifting mechanism, and the iron sheet is transferred to the lifting table, automatically rises to a position contacting with the pallet without stopping, automatically retreats without stopping the device, and places the remaining iron sheet on the pile of the lifting table. Because the weight of the sheet iron is large, the friction force of the supporting plate under the action of gravity is large through mechanical analysis, and scratches, scratches and impressions on the surface of the sheet iron are easily caused when the supporting plate is pulled out, so that the printing quality of the sheet iron is affected.

Detailed Description

Exemplary embodiments of the present invention are described in detail below. While these exemplary embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, it is to be understood that other embodiments may be realized and that various changes to the invention may be made without departing from the spirit and scope of the invention. The following more detailed description of the embodiments of the invention is not intended to limit the scope of the invention, as claimed, but is merely illustrative and not limiting of the invention's features and characteristics in order to set forth the best mode of carrying out the invention and to sufficiently enable those skilled in the art to practice the invention. Accordingly, the scope of the invention is limited only by the attached claims.

The sheet 60 of the present invention includes, but is not limited to, a single sheet or plate of relatively large mass, and the thickness of the sheet 60 is 0.1 to 1.5mm, such as a metal sheet 60 (tinplate, aluminum plate, copper plate, zinc plate, etc.), PVC sheet 60, plastic sheet 60, and other sheet products, and the present invention is not particularly limited to the type and thickness of the sheet.

With reference to fig. 1, by analyzing the structure of the feeder in the prior art, such as patent CN204488205U, as the weight of a sheet iron is large, the weight of a stack is more than hundreds of jin, and by mechanical analysis, the friction force of the supporting plate under the action of the weight of the sheet iron is large, which is easy to cause scratch and scratch on the surface of the sheet iron, thereby affecting the printing quality of the sheet iron; meanwhile, as the supporting plate is pulled out, the contact area of the upper iron sheet and the lower iron sheet is larger and larger, a certain adsorption force (orderly separation of magnetic attraction and air blowing) exists between the upper iron sheet and the lower iron sheet, and the larger the contact area is, the larger the adsorption force is, so that the acting force (the clamping force of the upper iron sheet and the lower iron sheet) born by the supporting plate is increased, the greater power is required for pulling out the supporting plate, the pulling-out time is prolonged, and the degree of scraping and marking on the upper surface of the lower iron sheet by the supporting plate is further increased; in addition, as the supporting plate has a certain thickness, in the extraction process, as the feeding pile falls down due to the height difference, vibration is generated on the whole pile, which is not beneficial to orderly separation of the flying device 10.

The invention is described by taking an iron printing coater as an example, the iron printing coater comprises an iron printing unit and a thin plate continuous uninterrupted feeder, wherein the thin plate continuous uninterrupted feeder and the iron printing unit are arranged on the same plane, and the thin plates 60 are orderly separated and continuously fed; the iron printing unit receives the sheet 60 conveyed by the sheet continuous feeder, and prints the sheet 60.

In order to realize continuous feeding of the metal printing coater, as shown in fig. 2, the continuous uninterrupted sheet feeder of the invention comprises a flying device 10, a travelling mechanism 20, a lifting mechanism 30 and a supporting mechanism 40; and a PLC controller (not shown) for controlling the flyer device 10, the travelling mechanism 20, the lifting mechanism 30 and the supporting mechanism 40, and the PLC controller may be a PLC controller in the prior art, and is not limited in particular.

The above-mentioned flying device 10 includes lifting material platform 12, adsorption nozzle 11 and blowing nozzle 13, can also have magnetic separator to the iron sheet metal, the magnetic separator is set up in the horizontal both sides (from the feed direction) of lifting material platform 12, the above-mentioned adsorption nozzle 11 and blowing nozzle 13 are used for separating the sheet metal 60 on lifting material platform 12 sequentially and realizing the conveying of the single Zhang Baoban; the tail end of the thin plate 60 separated by the separating device can be lifted by the adsorption nozzles 11 and then conveyed forwards, the number of the adsorption nozzles 11 is generally 2-3, the adsorption nozzles 11 are connected and communicated with the air inlet pipe 15, the air inlet pipe 15 is transversely arranged, the action of the adsorption nozzles 11 is controlled by the electromagnetic valve arranged on the air inlet pipe 15, the adsorption nozzles 11 intermittently stretch downwards, and the intermittent time is the moving speed of the single Zhang Baoban 60.

As shown in the figure, the lifting mechanism 30 is connected with the supporting mechanism 40, and is used for driving the supporting mechanism 40 to move up and down; the support mechanism 40 comprises a plurality of support elements 41 arranged at intervals, wherein the support elements 41 are used for supporting the remaining thin plates 60 on the lifting platform 12 during feeding. The supporting element 41 can be a supporting plate, a supporting rod or other shapes, the supporting element 41 can be inserted from any direction (not including the discharging direction) at the bottom of the feeding pile, the tray 61 of the feeding pile is provided with a plurality of sockets 62, the inserted length of the supporting element 41 can support the rest thin plate 60, the thin plate 60 does not shake, and the feeding stability of the thin plate 60 is ensured.

The avoidance area 14 for the bearing element 41 to ascend is formed in the flyer device 10, when the last sheet 60 on the bearing element 41 is conveyed away by the flyer device 10, the lifting mechanism 30 can drive the bearing element 41 to ascend 40-50mm to the avoidance area 14, so that the movement track of the sheet 60 in which the conveying progress is positioned is avoided, the conveying of the sheet 60 is prevented from being hindered, and the adsorption nozzle 11 and the blowing nozzle 13 can continuously and orderly separate and convey the sheet 60 connected on the lifting material table 12; therefore, the lifting mechanism 30 drives the motion path of the supporting element 41 to move upwards, stop moving, horizontally translate backwards, and then translate to exit the avoiding area 14 of the flying device 10, and the supporting element 41 is contacted but does not press the upper surface of the iron sheet of the material feeding pile, so that the problems of scratch, wiping or imprinting of the iron sheet are effectively solved.

As shown in fig. 6, the preferred holding member 41 can be inserted into the insertion opening 62 of the feeding stack tray 61 from the feeding side, and the thickness D of the holding member 41 is as thin as possible under the premise of ensuring the overall strength of the holding member 41 to meet the use requirement, so that the distance between the upper surface of the thin plate 60 of the continuous stack and the suction nozzle 11 can be reduced, and the possibility of empty opening of the suction nozzle 11 is effectively avoided.

For the length of the supporting element 41, the supporting element 41 is inserted into the insertion opening 62 of the tray 61 to at least support the remaining thin plate 60 without shaking, and in general, the length of the supporting element 41 is at least 1/2 of the width of the thin plate 60, preferably 2/3 to equal the width of the thin plate 60.

Compared with the prior art, the invention adopts the bearing element 41 to rapidly rise to the avoidance area 14, and the seamless connection of material feeding is realized between the material feeding pile and the material feeding pile (the time for the bearing element 41 to rise is less than or equal to the time for the intermittent conveyance of two adjacent thin plates 60 obtained by calculation of the invention), so that the uninterrupted continuous feeding of the thin plates 60 is realized structurally, the waste of the thin plates 60 is reduced, the possibility of empty sheets of the thin plates 60 is reduced, the production efficiency is improved, and the energy consumption is saved.

Further, considering the stability of the adsorption nozzle 11, as shown in fig. 6 and 7, when the supporting element 41 is lifted to the avoidance area 14, the supporting element 41 is higher than the bottom end of the adsorption nozzle 11 of the above-mentioned flying device 10, so that the problem that the supporting element 41 may not be lifted up, the supporting element 41 may touch the thin plate 60 when the adsorption nozzle 11 is lifted up, and the supporting element 41 may form scratches on the upper surface of the thin plate 60 is solved.

Meanwhile, the plane guide rail 23 plays a limiting role and also plays a pulling force role, wherein the limiting role effectively ensures the stability of the travelling mechanism 20, the gravity borne by the bearing element 41 can be transmitted to the plane guide rail 23 through the truss 31, the guide rail component 32 and the mounting seat 21, and the pulling force of the plane guide rail 23 counteracts part of the gravity acting force, so that the stability of the whole feeder is ensured. The power components may be servo motor 22, hydraulic motor, gasoline engine, and products on the market that can provide driving force.

Further, a gap for accommodating the suction nozzle 11 or the blowing nozzle 13 is arranged between the supporting elements 41, so that the interference of the suction nozzle 11 or the blowing nozzle 13 on the lifting of the supporting elements 41 is avoided, and the stable and uninterrupted feeding of the feeder is ensured.

Based on the feeder, the specific working process is as follows:

step S101, determining the residual thin plates 60 of the feeding pile, wherein a manual identification mode can be adopted, or the thickness of the residual thin plates 60 is monitored, and the number is generally about 50;

step S102, starting the feeder, then determining the position of the insertion opening 62 on the tray 61, inserting the supporting element 41 into the insertion opening 62, wherein the inserted length of the supporting element 41 meets a certain requirement, at least the rest thin plate 60 can be supported without shaking, and the inserted length is about 3/4 of the width of the thin plate 60 in general.

Step S103, lifting the supporting element 41 to enable the supporting element 41 to support the residual thin plate 60, and then continuously lifting the feeder and the residual thin plate 60 at a constant speed; simultaneously, the lifting material platform 12 of the flying device 10 descends, the tray 61 is removed, the material pile enters the lifting material platform 12 and then rapidly ascends, and in the process, the rest thin plate 60 is supported on the supporting element 41 to continue to ascend, and the speed is unchanged;

step S104, when the lower sensing element 44 on the supporting element 41 senses that the material pile is attached to the lower surface of the supporting element 41, the PLC feeds back a signal to enable the rising speed of the supporting element 41 to be consistent with the rising speed of the lifting material table 12 of the flying device 10 and to rise synchronously;

in step S105, when the last sheet 60 on the supporting element 41 is transported away by the feeder apparatus 10, the lifting platform 12 of the feeder apparatus 10 keeps the set lifting speed unchanged, and the supporting element 41 is lifted to the avoidance area formed inside the feeder apparatus 10 within the set time (the time of lifting the supporting element 41 is less than or equal to the time of intermittent transportation of two adjacent sheets 60), and the movement is stopped for 3-5 seconds.

Step S106, the travelling mechanism 20 moves backward to drive the bearing element 41 to translate and exit the avoidance area 14 of the flyer device 10, and wait for the next material change.

The entire process, while contacting, the support member 41 does not press against the upper surface of the sheet 60 of the batch pile, solving the prior art problems of scratching, scoring, scuffing or marking the sheet 60.

Finally, it should be noted that the above embodiments are merely illustrative of the technical solution of the present invention and not limiting, and it should be pointed out that modifications or equivalent arrangements can be made by those skilled in the art without departing from the principles of the present invention, which shall not depart from the spirit and scope of the present invention, and are intended to be covered by the appended claims.
