Examples

FIG. 1 is a schematic structural view of an inner glaze system B001 according to an embodiment of the present invention; FIG. 2 is a top view of FIG. 1; fig. 3 is a schematic structural view of the rotary table 200 for enamel coating and the clamping arm 100 for enamel coating in fig. 2, which additionally shows a bottle W0 to be enamel coated. Referring to fig. 1, 2 and 3, the inner glaze system B001 in the present embodiment includes an inner glaze rotating table 200, and a plurality of inner glaze clasps 100 connected to a circumference of the inner glaze rotating table 200. The inner glaze clamping holder 100 includes a clamping mechanism 20 capable of clamping the bottle W0 and a rotary driver 30 capable of driving the clamped bottle W0 to be turned upside down (see the following drawings for details of the structure of the inner glaze clamping holder 100, the clamping mechanism 20 and the rotary driver 30). The first bottle feeding station, the inner glaze feeding station and the first bottle descending station are distributed on the periphery of the inner glaze rotating table 200 in an end-to-end annular distribution mode, and each inner glaze holding clamp 100 is driven by the inner glaze rotating table 200 to circularly move among the first bottle feeding station, the inner glaze feeding station and the first bottle descending station. The first bottle feeding station is used for providing bottle parts W0 to be subjected to inner glazing. The glazing station is provided with an inner glaze applying structure S001 having a glaze supplying system S20 (please refer to the following drawings for the specific structure of the inner glaze applying structure S001 and the glaze supplying system S20). The inner glaze clamping arm 100 can carry the bottle W0 clamped from the first bottle feeding station and insert the bottle W0 into the glaze supply opening of the glaze supply system s20 with the opening facing downward, so that the glaze discharged from the glaze supply opening of the glaze supply system s20 enters the bottle W0 and adheres to the inner surface of the bottle W0 to realize glazing. The first bottle lowering station is used for receiving bottle pieces W0 which are internally glazed.

The use steps of the inner glaze system B001 in the embodiment of the invention can be as follows:

the inner glaze clamping hand 100 grabs a bottle W0 to be subjected to inner glaze application from a first bottle feeding station; under the driving of the inner glaze rotating table 200, the inner glaze clasping hand 100 carries the bottle piece W0 to rotate to the upper inner glaze station, and the inner glaze applying operation is carried out by an inner glaze applying structure S001 arranged at the upper inner glaze station; after the inner glaze is applied, the inner glaze clamping hand 100 is continuously driven by the inner glaze rotating table 200 to rotate to a subsequent station, for example, directly conveyed to a position corresponding to a first lower bottle station, and the bottle W0 with the inner glaze applied thereon is placed at the first lower bottle station. The bottle member W0 placed at the first bottle dropping station can be directly off-line or continuously processed by other operation procedures. The inner glaze clamping hand 100 after the bottle W0 is put down can drive the inner glaze rotating table 200 to return to the first bottle feeding station again, and the next cycle of operation is performed.

The inner glaze system B001 in the embodiment is provided with a circulating station in an annular mode and drives the inner glaze clamping handles 100 to sequentially operate the bottle W0 through the inner glaze rotating table 200 to perform operations such as bottle feeding, inner glaze applying, bottle discharging and the like, and has the advantages of simple and reasonable structure, small occupied area and capability of efficiently finishing the inner glaze feeding operation of the bottle W0. The inner glaze system B001 in the embodiment can also be easily configured with an automatic control system, so as to realize the high-efficiency automatic inner glaze application on the bottle piece W0.

In one embodiment of the present invention, the inner glaze system B001 further comprises a belt conveyor T1. One end of the belt conveyor T1 is an upper bottle point for positioning an upper bottle, the other end of the belt conveyor T1 is positioned at a first upper bottle station, and the belt conveyor T1 is configured to convey bottle pieces W0 placed from the upper bottle point to the first upper bottle station.

In order to accurately place the bottle W0, an upper bottle positioning machine 300 for assisting in positioning the upper bottle is further provided at the upper bottle point. The positioning structure of the upper bottle positioning machine 300 can be a V-shaped opening structure, and when the upper bottle is fed, the bottle piece W0 is only required to be placed on two sides of the fitted V shape, so that the accurate upper bottle can be realized. Of course, when the transport of the bottle member W0 is required after the completion of the loading, the V-port structure needs to be withdrawn. In this embodiment, a linear actuating cylinder can be used to drive the V-port structure to extend for positioning the upper bottle and retract to avoid blocking the transfer of the vial W0. If there are a plurality of bottle members W0 in this embodiment, the number of corresponding V-shaped opening structures may also be multiple, that is, the linear driving cylinder drives a plurality of V-shaped opening structures to extend or retract simultaneously. In this embodiment, the bottle can be positioned manually or automatically.

In some cases, there may be dust, impurities, etc. in the bottle W0 to be underglazed on the upper thread, which affects the quality of the overglaze. To solve this problem, the inner glaze system B001 of the present embodiment further includes an in-bottle air-blowing dust remover 400. With reference to fig. 4, an in-bottle blow and dust extractor 400 is positioned between the upper bottle point and the first upper bottle station. The bottle W0 coming on line from the bottle feeding point is conveyed by the belt conveyor T1 to be blown by the in-bottle blowing dust remover 400 to remove impurities in the bottle and then conveyed to the first bottle feeding station. The in-bottle blowing and dust removing machine 400 in this embodiment may be an apparatus having a plurality of blowing pipes 420. When in use, the air blowing pipe 420 is inserted from the bottle mouth of the bottle piece W0, and then air blowing and dust removing operations are carried out. In order to prevent the blown dust and impurities from affecting the environmental quality, the in-bottle blowing dust collector 400 is provided with a cover 410 for preventing the dust from being blown out. Of course, the in-bottle blow dust collector 400 may not be provided where there are no such dust, foreign matter problems or other considerations (e.g., cost, etc.). The bottle W0 subjected to air blowing and dust removal by the in-bottle air blowing dust remover 400 is conveyed to a first bottle feeding station by a belt conveyor T1 and waits for subsequent glazing operation.

In this embodiment, in order to further adapt to operations of bottle feeding at the first bottle feeding station, applying the inner glaze at the upper inner glaze station, bottle discharging at the first bottle discharging station, etc., the inner glaze clamping hand 100 in this embodiment is designed with a unique structure.

Fig. 5 is a schematic structural diagram of an embodiment of the inner glaze clamping hand 100 in the embodiment; fig. 6 is a view taken along direction a of fig. 5. In order to express the clamping relationship between the inner glaze gripper 100 and the bottle W0, the clamped bottle W0 is additionally shown by dotted lines in fig. 5 and 6, and obviously, the bottle W0 does not belong to the integral part of the inner glaze gripper 100 claimed in the present application. Referring cooperatively to fig. 7, the bottle W0 in the present embodiment includes a large bottle belly W2 and a relatively small bottle neck W1.

Referring to fig. 5-6, the inner glaze clamping holder 100 in the present embodiment includes a frame 10, a clamping mechanism 20, and a rotary driver 30.

The clamping mechanism 20 includes two clamping actuators 20a spaced from each other and coaxially and rotatably engaged with the frame 10, and a clamping portion 20b configured to be connected between the two clamping actuators 20a and capable of being clamped or released by the two clamping actuators 20a. The holding portion 20b includes a neck clamp 21 for holding the bottle neck W1 and a belly clamp 22 for holding the bottle belly W2. The opposite side surfaces of the two first holding strips 21a constituting the neck clamp 21 are provided with first engaging portions 21b corresponding to the shape of the neck portion W1 of the bottle. The side surfaces of the two second holding strips 22a constituting the bottle belly clip 22 opposite to each other are provided with second engaging portions 22b corresponding to the shape of the bottle belly W2. The rotary drive 30 is drivingly connected to the gripper mechanism 20 and is configured to drive the gripper mechanism 20 in a reverse direction. Alternatively, the clamping actuator 20a is a clamping cylinder with telescopic ends 2a on both sides. Two ends of the second clamping strip 22a are respectively and correspondingly fixed on the telescopic ends 2a at two corresponding sides. Alternatively, the rotary actuator 30 may be a rotary air cylinder, and may be driven by the same driving power as the clamp actuator 20a, i.e., both driven pneumatically. Of course, in other embodiments, electric or hydraulic driving may be used.

The inner glaze clamping hand 100 in this embodiment can realize the following actions: under the drive of the clamping actuator 20a, the neck clamp 21 and the belly clamp 22 respectively clamp the neck part W1 and the belly part W2 of the bottle, and under the drive of the rotary driver 30, the clamping structure and the clamped bottle W0 are driven to realize the turnover, so that the bottle mouth is vertically downward, and the preparation of actions such as the function of spraying inner glaze and the like is completed. In practical use, the main function of the bottle opening which faces downwards vertically is to pour out impurities remained in the bottle, so that the inner glaze is prevented from being influenced.

In this embodiment, press from both sides 22 and centre gripping bottle spare W0 simultaneously through the bottleneck and press from both sides 21 and the bottle tripe, can make the centre gripping of bottle spare W0 tight, bottle spare W0 each department atress is even, and bottle spare W0 is difficult for pressing from both sides the bits of broken glass, and the relative position of bottle spare W0 and fixture 20 is stable, is favorable to the accurate location of bottle spare W0, conveniently carries out operations such as interior glaze to bottle spare W0.

In one embodiment of the present embodiment, each of the inner glaze clamping holders 100 is provided with a plurality of clamping positions for clamping the bottle W0, so as to clamp and operate a plurality of bottles W0 at a time. This may be achieved by a plurality of first engagement portions 21b (five as shown in fig. 5 and 6), and a plurality of first engagement portions 21b are provided at intervals along the first clamping bar 21a and between the two clamping actuators 20a. The second engaging portion 22b is provided in plural, and the plural second engaging portions 22b are provided at intervals along the second holding bar 22a and are located between the two holding actuators 20a. Through the structure, a plurality of bottles W0 can be clamped at one time, and the operation efficiency can be improved by multiple times. Optionally, the first holding strip 21a is an elongated plate-shaped structure, and an inner side surface thereof is provided with an arc-shaped notch. The first engaging portion 21b is of a fan-shaped structure, and the protruding side thereof is engaged with the arc-shaped notch, and the recessed side thereof is used for engaging with and clamping the neck W1 of the bottle. Optionally, the concave side of the first matching portion 21b is in a circular arc shape with a diameter larger than that of the bottle neck portion W1, and the two opposite first matching portions 21b jointly realize clamping of the bottle neck portion W1 from two sides, which has the advantage of stable clamping. Similarly, the second holding strip 22a is a strip-shaped plate-shaped structure, and the inner side surface thereof is provided with an arc-shaped notch. The second engaging portion 22b is a fan-shaped structure, and the protruding side thereof is engaged with the arc-shaped notch, and the recessed side thereof is used for engaging with and clamping the bottle belly portion W2. Alternatively, the concave side of the second fitting portion 22b is in the shape of a circular arc having a diameter larger than the diameter of the neck portion W1 of the bottle, and the two opposite second fitting portions 22b jointly realize clamping of the bottle belly portion W2 from both sides, which has the advantage of stable clamping.

In other embodiments, the bottle W0 may be provided one bottle W0 at a time, two bottles W0 at a time, a plurality of bottles W0 at a time, etc., as needed. Correspondingly, the length, size and shape of the first holding strip 21a and the second holding strip 22a, the number of the first engaging portion 21b and the second engaging portion 22b, and the like can also be adaptively adjusted.

In this embodiment, the first engaging portion 21b and the second engaging portion 22b can be made of soft materials such as rubber and soft plastic, so as to further avoid crushing the bottle W0 and increasing the clamping friction force, and avoid loosening.

With continued reference to fig. 5 and 6, in the present embodiment, the frame 10 optionally includes a bottom frame 11 and two side plates 12 connected to two ends of the bottom frame 11 at intervals. The two clamp actuators 20a are correspondingly rotationally coupled to the two side plates 12. The two side plates 12 and the bottom frame 11 jointly define a U-shaped movable space Q1, and the clamping mechanism 20 is positioned in the movable space Q1 and is limited to act in the movable space Q1. The frame 10 in this embodiment defines a U-shaped movable space Q1, and the clamping mechanism 20 is located in the movable space Q1 and is limited to operate in the movable space Q1, so as to prevent the clamping mechanism from mechanically interfering with other structures during operation (for example, when the clamping mechanism is driven by the rotary driver 30 to turn over), which may cause mechanical failure or safety accident. In another embodiment of the present invention, the frame 10 may be provided with another suitable structure, for example, an open box with five closed sides, so as to achieve a good attachment of the clamping mechanism 20. In addition, the chassis 11 in this embodiment may further be provided with a mounting hole K1 for facilitating mounting and connecting other structures when necessary.

Referring to fig. 5 and 6 again, in one embodiment of the present invention, the bottle neck clamp 21 and the bottle belly clamp 22 are located on two sides of the rotation axis Y1 of the clamping actuator 20a. Optionally, after the bottle neck clamp 21 and the bottle belly clamp 22 are located at positions relative to the rotation axis Y1, the moment of inertia of the whole clamping mechanism 20 and the clamped bottle W0 relative to the rotation axis Y1 is exactly zero, so that the control feedback efficiency is high and the energy consumption is minimum when the clamping mechanism 20 drives the bottle W0 to turn over.

The bottle neck clamp 21 and the bottle belly clamp 22 in this embodiment are both driven by the clamp actuator 20a to achieve clamping or unclamping. The bottle neck clamp 21 and the bottle belly clamp 22 can be respectively and directly connected with the clamping actuator 20a and can be synchronously clamped or released directly under the driving of the clamping actuator 20a. Of course, in this embodiment, the clamping actuator 20a is fixedly connected to the bottle belly clip 22 and is used to drive the bottle belly clip 22 to clamp or release. The bottle neck clamp 21 is fixedly connected to the bottle belly clamp 22 through a connecting piece 23 and can be synchronously clamped or loosened along with the bottle belly clamp 22. That is, the neck clamp 21 is indirectly connected to the clamp actuator 20a. One reason for adopting this arrangement in this embodiment is that the bottle belly W2 is larger in size and the bottle neck W1 is smaller in size, which makes the bottle neck clamp 21 closer to the middle position and the bottle belly clamp 22 closer to the outer side in the width direction, and the direct connection with the clamp actuator 20a is possible, but there may be problems of appearance, stress, and the like in the structural design. In order to ensure that the transmission between the bottle neck clamp 21 and the bottle belly clamp 22 is stable, the first clamping strip 21a and the second clamping strip 22a which are positioned on the same side are fixedly connected through two connecting pieces 23 which are spaced along the length direction. Optionally, one end of the connecting member 23 is fixedly connected to the corresponding first clamping strip 21a, and the other end is provided with a strip-shaped groove C1, and the second clamping strip 22a is configured to be capable of being connected to any position of the strip-shaped groove C1 in the length direction, so as to adjust the distance between the second clamping strip and the corresponding first clamping strip 21 a. When bottle members W0 of different sizes are correspondingly clamped, normal clamping may need to be achieved by adjusting the relative position between the first clamping strip 21a and the second clamping strip 22 a; or by adjusting the relative positions to achieve the aforementioned cancellation of the moment of inertia to zero.

In conclusion, the inner glaze clamping hand 100 in this embodiment can stably and uniformly clamp the bottle W0 and drive the bottle W0 to perform the set action, and has the advantages of uniform stress at each position of the bottle W0, difficulty in breaking, stable relative position between the bottle W0 and the clamping mechanism 20, benefit of accurate positioning of the bottle W0, and convenience in performing inner glaze application and other operations on the bottle W0.

Finally, it should be noted that the inner glaze holder clamp 100 in the embodiment of the present invention may also be used for clamping workpieces of other shapes, and in this case, it may be necessary to design the structure of the neck clamp 21 and the bottle belly clamp 22 adaptively.

In some embodiments of the present invention, the inner glaze rotating table 200 is provided with a vertical guide rail 210 at a side thereof, and the inner glaze clamping holder 100 is fittingly connected to the guide rail 210 and can be driven to vertically move up and down along the guide rail 210.

The inner glaze clamping hand 100 in the embodiment is adopted to clamp a plurality of bottle parts W0 from a first bottle feeding station in sequence and then transfer to an inner glaze feeding station to carry out inner glaze feeding operation.

The inner glaze-applying structure S001 in the present embodiment can be configured in various forms by supplying glaze and glazing into the bottle W0. FIG. 8 is a schematic structural view of one embodiment of an inner glaze applying structure S001 in the present embodiment; fig. 9 is a top view of fig. 8 (fig. 8, 9 additionally show one glazing subject bottle W0 of the present inner glaze glazing structure S001); fig. 10 is a structural view of the glaze stripping portion in the present embodiment. Referring to fig. 8, 9 and 10, the inner-glaze glazing structure S001 in the present embodiment includes a glaze supply system S20, a fitting nozzle S30 and a return element S50. The glaze supply system s20 is provided with a plurality of glaze outlet pipes s40 which are opened upwards, and the glaze supply system s20 can discharge glaze from the outlets of the glaze outlet pipes s40. The fitting nozzle s30 has a through hole s301 penetrating its upper and lower end surfaces s 02. The outlet of the enamel outlet pipe s40 corresponds from below to the opening s301. The matching nozzle s30 is elastically supported at the upper end of the return piece s50, and can overcome the return force of the return piece s50 to move downwards under the action of external force so as to enable the lower end of the through hole s301 of the matching nozzle s30 to be communicated with the outlet of the glaze outlet pipe s40 in a sealing mode, and enable the glaze outlet of the glaze outlet pipe s40 to be communicated with the upper end of the through hole s301 only.

Fig. 11 is a schematic view of the state of use of the inner glaze applying structure S001 in the present embodiment. Referring to fig. 10 and 11, in the present embodiment, when the internal glaze applying structure S001 is used, the bottle W0 (or other workpiece to be subjected to internal glaze application) is pressed down on the fitting nozzle S30 in an inverted state with the opening facing downward, so that the upper end of the through hole S301 of the fitting nozzle S30 is communicated with the bottle opening. The bottle member W0 and the fitting nozzle s30 continue to move downward against the restoring force of the restoring member s50, so that the lower end of the through opening s301 of the fitting nozzle s30 is sealingly communicated with the outlet of the glaze outlet pipe s40. Then, the glaze supply system s20 discharges glaze from the outlet of the glaze discharge pipe s40, and glaze water enters the inner cavity of the bottle W0 through the bottle opening and adheres to the inner surface of the bottle W0, so that glazing is realized. After glazing is finished, the bottle piece W0 is taken away, the matching nozzle s30 returns under the action of the return force of the return piece s50 and is separated from the glaze outlet pipe s40, and redundant glaze water flows out from the lower end of the opening s301.
