Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The application discloses piece mechanism turns over, it includes: a sheet feeding assembly 10 for feeding the plate member 1 forward; the overturning assembly 20 is arranged outside the sheet conveying assembly 10, can receive the plate 1 on the sheet conveying assembly 10 at a first station, and overturns the plate 1 to a second station, so that the plate 1 can be turned over and returned to the sheet conveying assembly 10 again.

As will be readily understood, the direction of the sheet feeding assembly 10 for conveying the sheet member 1, i.e., the direction in which the first station points toward the second station. For example, in one embodiment, referring to fig. 1, the direction of the sheet conveying member 1 of the sheet conveying assembly 10 is the left-right direction (the direction in fig. 1 is based on the actual direction of the index); at this time, the first station is on the left side of the turnover assembly 20, and the second station is on the right side of the turnover assembly 20; the plate member 1 is transferred from left to right via the sheet feeding assembly 10.

It should be noted that the first station and the second station are not absolutely a specific position, but refer to a position where the plate member 1 gradually enters the turnover assembly 20 and the plate member 1 gradually leaves the turnover assembly 20, which is a range.

Wherein, upset subassembly 20 includes: the turntable 21 and the turntable driving member 22, the turntable driving member 22 is connected with the turntable 21 and can drive the turntable 21 to rotate; a support member 23 provided on the turntable 21; wherein, the turntable 21 avoids the position of the supporting piece 23 and is provided with at least one through linear channel 24; when the linear channel 24 is rotated to be parallel to the conveying direction of the sheet feeding assembly 10, the plate member 1 on the sheet feeding assembly 10 can directly pass through the turnover assembly 20 and move downstream.

It should be explained that the turntable 21 is substantially cylindrical; and the turntable driving member 22 is connected to the position of the center of the turntable 21. At this time, referring to fig. 1, fig. 2 and fig. 3 specifically, the axial direction of the rotary table 21 is perpendicular to the conveying direction of the sheet feeding assembly 10, and the center of the circle of the rotary table 21 faces the sheet feeding assembly 10; the supporting member 23 extends along the radial direction of the output shaft of the turntable driving member 22 and points to the center of the turntable 21 (i.e. the rotation center of the turntable at this time); thus, when the turntable 21 rotates to a certain angle, the extending direction of the supporting member 23 is just parallel to the conveying direction of the film feeding assembly 10; specifically, when the supporting member 23 is just parallel to the conveying direction of the sheet feeding assembly 10, the supporting member 23 is just at the first station, and the sheet feeding assembly 10 continuously conveys the sheet 1 forward, so that the sheet 1 can actively enter the supporting member 23.

Of course, it is easy to think that, according to the actual installation mode of the rotary table 21 and the sheet feeding assembly 10, the extending direction of the supporting member 23 may also be adjusted, as long as it is ensured that when the rotary table 21 rotates to a certain angle, the length direction of the supporting member 23 is exactly parallel to the conveying direction of the sheet feeding assembly 10, so as to facilitate the plate 1 to enter the supporting member 23, and the application is not limited.

When the supporting piece 23 is arranged along the radial extension of the output shaft of the turntable driving piece 22 and points to the rotation center of the turntable 21, the linear channel 24 passes through the axis of the output shaft of the turntable driving piece 22; thus, when the rotary table 21 rotates to another angle, the linear channel 24 is also parallel to the conveying direction of the sheet conveying assembly 10; at this time, the plate member 1 moves forward on the sheet feeding assembly 10, and the part of the plate member which would otherwise enter the supporting member 23 and be supported by the supporting member 23 can directly pass through the linear passage 24, so that the whole plate member 1 passes through the turnover assembly 20 without being hindered to move downstream.

Of course, it is easy to think that the extending direction of the supporting member 23 is adjusted, and the extending direction of the linear channel 24 is also adjusted, so as to ensure that the rotation of the rotary table 21 can make the supporting member 23 parallel to the conveying direction of the sheet feeding assembly 10 and make the linear channel 24 parallel to the conveying direction of the sheet feeding assembly 10, and further make the sheet turning mechanism realize the turning transportation of the sheet 1 and the direct transportation of the sheet 1 without turning.

In one embodiment, referring to fig. 1, the flipping module 20 includes only two sets of oppositely disposed supporting members 23; when the plate 1 needing to be turned over is transferred from left to right by the plate conveying assembly 10 and reaches the first station, a supporting piece 23 is just positioned at the first station; then, under the conveying of the sheet conveying assembly 10, the sheet 1 gradually enters the supporting member 23 and is supported by the supporting member 23; then, the turntable driving member 22 drives the turntable 21 to drive the supporting member 23 to rotate clockwise 180 ° around the axis of the output shaft thereof, so that the supporting member 23 is transferred to the second station; at this point, the plate 1 is flipped over and returned to the blade assembly 10; the sheet feeding assembly 10 continues to move from left to right, and drives the turned plate 1 to gradually leave the supporting piece 23 to move downstream; after the plate 1 has completely left the support element 23, the turntable drive element 22 drives the turntable 21 to rotate through another 180 °, so that the support element 23 returns to the first station for receiving the next plate 1 to be turned over.

Further, in order to stably support the plate member 1, the length of the support member 23 extending in the radial direction of the output shaft of the turntable driving member 22 (toward the rotation center of the turntable 21) may be set to have a length of 2/3 of the plate member 1. So, after plate 1 got into supporting piece 23, supporting piece 23 can hold most plate 1, avoids plate 1 in the upset in-process, because have more part not supported and easily follow supporting piece 23 and drop.

Further, in order to better control the plate 1 on the supporting member 23 and prevent the plate 1 from falling off, or prevent the plate 1 from being excessively displaced during the turnover process to affect the downstream receiving and processing, in one embodiment, the end surface of the supporting member 23, which supports the plate 1, is recessed to form a slot into which the plate 1 can be inserted. Referring to fig. 2, 4 or 5, the body of the support member 23 is an elongated rectangular block; the end surface of the rectangular block close to the sheet feeding assembly 10 is sunken inwards to form a clamping groove; the clamping groove has a certain depth and can be used for the plate 1 to be inserted; so, plate 1 can be injectd to a certain extent to two relative cell walls of draw-in groove, guarantees plate 1's stable bearing.

Furthermore, since the turntable 21 needs to be connected to the turntable driving member 22, and the structure of the turntable driving member 22 is inconvenient for providing a straight passage for the plate member 1 to pass through, the tilting assembly 20 preferably supports the side of the plate member 1. When the part of the plate 1 inserted into the slot is more, the slot can stably support the plate 1 and the plate 1 cannot fall out from the open end of the slot, a group of turning assemblies 20 can be arranged on one side of the plate feeding assembly 10 to realize stable turning of the plate 1. When the plate 1 is wide and only a small part of the side edge of the plate 1 can be inserted into the slot, it is preferable that a set of turnover assemblies 20 are respectively disposed at two sides of the sheet feeding assembly 10, and the two sets of turnover assemblies 20 are oppositely disposed and can respectively hold one side of the plate 1 in the width direction.

Specifically, the sheet turning mechanism includes two sets of turning assemblies 20; the two groups of overturning assemblies 20 are oppositely arranged at two sides of the sheet feeding assembly 10; at least at the first station, the two sides of the plate 1 protrude out of the sheet feeding assembly 10, so that the supporting members 23 of the two sets of overturning assemblies 20 can support one side of the plate 1 respectively, further stably support the plate 1 and realize overturning. Referring to fig. 1, two sets of turnover assemblies 20 are disposed on two sides of the sheet feeding assembly 10 in opposite directions. At this time, each group of turning assemblies 20 may include a turntable 21, a supporting member 23 disposed on the turntable 21, and a turntable driving member 22 for driving the turntable 21 to rotate, and the two groups of turning assemblies 20 move independently. Or each group of turning assemblies 20 comprises a turntable 21 and a bearing piece 23 arranged on the turntable 21, but the two groups of turntables 21 are driven to rotate synchronously by a group of turntable driving pieces 22; referring specifically to fig. 2 and 3, the turntable driving member 22 is a servo motor, the output end of the servo motor is provided with a lead screw, and the two groups of turntables 21 are communicated with the lead screw through a synchronous belt assembly; therefore, the servo motor rotates to drive the screw rod to rotate and can drive the two groups of turntables 21 to synchronously rotate.

Furthermore, the groove end of the clamping groove can be ground into a round angle, so that the plate 1 entering the clamping groove can be prevented from being scratched.

In another embodiment, the supporting member 23 may be formed by two spaced limiting blocks disposed oppositely; at this time, the supporting member 23 is equivalent to a slot formed by invaginating on the rectangular block in the previous embodiment and completely penetrates through the rectangular block, the specific use mode is similar to that of the previous embodiment, and the position of the plate 1 is limited to a certain extent in the overturning process when the plate 1 passes in and out through the two limit blocks with the closer positions. And will not be described in detail herein.

In another embodiment, the supporting member 23 is provided with a fixing member; when the supporting piece 23 supports the plate 1, the fixing piece can fix the plate 1 on the supporting piece 23, and then the plate 1 is prevented from being separated from the supporting piece 23 in the overturning process.

In this embodiment, the fixing member may be a suction cup, which can suck the plate 1, so as to limit the plate 1 thereon, and facilitate driving the plate 1 to rotate; or, the fixing member may also be a clamping plate, which can clamp the plate 1, and further fix the plate 1 on the supporting member 23, so as to facilitate driving the plate 1 to rotate.

The overturning assembly 20 comprises at least one set of supporting members 23; at the moment, the turntable driving part 22 drives the turntable 1 to drive the group of supporting parts 23 to reciprocate between the first station and the second station, and the turntable 21 rotates 180 degrees each time; when the supporting piece 23 reaches the first station, the rotating disc 21 stops rotating, and the plate 1 actively moves into the supporting piece 23 under the driving of the sheet feeding assembly 10; when the supporting piece 23 reaches the second station, the rotating disc 21 stops rotating, and the plate 1 is driven by the rotating disc driving piece 22 to move out of the supporting piece 23 and move downstream.

To improve the turnover efficiency, the turnover assembly 20 may include a plurality of sets of supports 23; the multiple sets of supporting pieces 23 are arranged on the periphery of the rotating disc 21 at intervals along the circumferential direction. Thus, when one supporting member 23 receives the plate member 1 at the first station, another supporting member 23 releases the turned plate member 1 at the second station, so as to ensure the continuous turning of the plate member 1.

Specifically, referring to fig. 4 and 5, a plurality of sets of supporting pieces 23 are disposed at equal intervals on the outer periphery of the turntable 21; an even number of sets of supporting members 23 are provided on the turntable 21, and these supporting members 23 are arranged in pairs — a pair of supporting members 23 are arranged oppositely, and the line thereof passes through the rotation center of the turntable 21. In this way, the turntable driving member 22 drives the turntable 21 to rotate by the same angle each time, so that one set of the supporting members 23 is at the first station, and the other set of the supporting members 23 paired with the set of the supporting members 23 is at the second station.

Additionally, the inversion assembly 20 may also include a plurality of linear channels 24; for example, when there are multiple sets of the supporting members 23, two adjacent sets of the supporting members 23 may open the straight passage 24.

In order to facilitate the arrangement of the turntable 21 and the support member 23, the turnover assembly 20 further includes a chassis 25, and the turntable 21 and the support member 23 are arranged on the chassis 25. With specific reference to fig. 4 and 5, the chassis 25 is disc-shaped, and one side of the supporting member 23 away from the film feeding assembly 10 can be fixedly arranged on the chassis 25, so that the mounting stability of the supporting member 23 and the rotation safety can be ensured. Further, in order to reduce the driving load of the turntable driving member 22, the portion of the chassis 25 where the turntable 21 and the supporting member 23 are not installed may be hollowed out, thereby reducing the weight of the chassis 25.

In order to convey the plate 1 conveniently, the plate conveying assembly 10 may be a conveyor belt assembly, and includes a driving wheel 11, a driven wheel 12, and a conveyor belt 13 sleeved between the driving wheel 11 and the driven wheel 12; the driving wheel 11 is connected with a sheet feeding driving part 14; the sheet feeding driving part 14 acts to drive the driving wheel 11 to rotate, and further drives the driven wheel 12 to rotate along with the conveying belt 13, so that the conveying belt 13 is driven to circularly flow.

At this time, the plate member 1 is placed on the upper surface of the belt 13, and moves forward following the belt 13. The sheet feeding driving member 14 may be a motor, and the motor acts to drive the driving wheel 11 to rotate.

Further, in the case that the plate member 1 is wide, the sheet feeding assembly 10 may include two sets of side-by-side, spaced conveyor belt assemblies; at this time, the conveyor belts 13 are circulated in a direction in which the first station is directed to the second station (i.e., in a left-right direction in fig. 1), and the two sets of conveyor belts 13 are arranged side by side in a horizontal plane perpendicular to a direction in which the first station is directed to the second station (i.e., in an up-down direction in fig. 1) so as to stably support the plate member 1.

Of course, in other embodiments, the sheet feeding assembly 10 may also adopt a conveying roller or a conveying platform, and the sheet 1 can be conveyed.

In order to ensure the accurate operation of the equipment, the sheet turning mechanism also comprises a first detection piece 2, wherein the detection end of the first detection piece 2 is over against the first station, and can detect the plate 1 at the first station; and/or, the second detection piece 3, the detection end of the second detection piece 3 is just right to the second station, can detect the plate 1 of second station department.

It should be explained that the first detecting member 2 and the second detecting member 3 may have various functions. For example, when a plate member 1 arrives at the first station to be turned over, a supporting member 23 needs to arrive at the first station to support the plate member 1; at this time, a first detecting member 2 may be provided, which detects that the plate member 1 arrives at the first station, and transmits a signal to the control system, and the control system may control the turntable driving member 22 to operate, and drive the turntable 21 to rotate by a certain angle, so that an empty supporting member 23 arrives at the first station. It should be added that if the supporting member 23 is a rectangular block and the block is provided with a slot, the first detecting member 2 needs to be arranged in advance before the position where the supporting member 23 receives the plate 1, so that an empty supporting member 23 is firstly rotated to the receiving position and then directly receives the plate 1, and the situation that the supporting member 23 arrives at the receiving position later than the plate 1 and causes the slot wall of the supporting member 23 to interfere with the plate 1 is avoided. Similarly, set up second detection piece 3 at the second station, can detect every carousel 21 rotation, whether transfer a plate 1 to other mechanism actions of low reaches. At this time, the first and second detecting members 2 and 3 may employ photoelectric sensors.

For another example, the plate 1 needs to be turned over, that is, the plate 1 has a front side and a back side; the first detection piece 2 is arranged at the first station, so that whether the front surface or the back surface of the current plate 1 needs to be turned over or not can be detected; subsequently, the first detecting member 2 transmits information to the control system, which controls the rotation of the turntable driving member 22 by a desired angle according to the facing of the plate member 1, so that an empty supporting member 23 is brought to the first station when the plate member 1 needs to be turned over, and so that the linear passage 24 is parallel to the direction in which the plate member 1 is conveyed by the sheet feeding assembly 10 when the plate member 1 does not need to be turned over. In a similar way, the second detection piece 3 is arranged at the second station, so that whether the plate 1 is a front surface or a back surface can be detected, and the mechanism corresponding to the downstream extracts the required plate and performs related processing. At this time, the first detecting member 2 and the second detecting member 3 may employ CCD cameras.

For another example, in an actual use mode, the sheet feeding assembly 10 is not stopped, and the plate member 1 is always fed forward; that is, after the plate member 1 enters the supporting member 23 at the first station, if the supporting member 23 is not rotated in time, the plate member 1 is continuously rubbed against the conveying surface of the sheet feeding assembly 10 because it is limited by the supporting member 23. At this time, by providing the first detection member 2 at the first station, it can be detected that the plate member 1 has reached the support member 23; subsequently, the first detecting member 2 transmits information to the control system, and the control system controls the turntable driving member 22 to drive the turntable 21 to rotate in time. Similarly, the second detection part 3 is arranged at the second station, so that whether the plate 1 completely leaves the supporting part 23 can be detected, and the rotary table driving part 22 is prevented from being driven in advance before the plate 1 leaves. At this time, the first and second detecting members 2 and 3 may employ photoelectric sensors.

For example, in a practical use mode, the sheet feeding assembly 10 is not stopped, and the plate member 1 is always conveyed forwards; at this time, on the sheet feeding assembly 10, the plate members 1 delivered to the first station are preferably placed on the sheet feeding assembly 10 at equal intervals and conveyed forward, so that the turntable driving member 22 is rotated at fixed angles at regular intervals to control the equipment tempo. Specifically, after one plate 1 enters one empty supporting member 23, the turntable driving member 22 rotates to drive the turntable 21 to rotate a certain angle, so that another empty supporting member 23 reaches the first station, and at the same time, another plate 1 enters the empty supporting member 23. At this time, a plurality of first detecting members 2 may be disposed at equal intervals on the first station and the conveying path of the sheet feeding assembly 10 upstream of the first station to detect whether the conveyed sheet members 1 have a uniform pitch. Similarly, a plurality of groups of second detection pieces 3 are arranged on the second station and the downstream of the second station and on the conveying path of the sheet conveying assembly 10, so that whether the output and turned-over sheet pieces 1 are conveyed downstream at equal intervals can be detected, and the downstream equipment can process the sheet pieces conveniently.

In order to ensure that the turnover assembly 20 accurately receives the plate 1 at the first station, the plate turnover mechanism further comprises a regulating assembly 30 which is arranged at the upstream of the turnover assembly 20 and is used for regulating the plate 1 on the plate feeding assembly 10; the normalizing assembly 30 comprises: the regulating piece 31 and the regulating driving piece 32, the regulating driving piece 32 is connected with the regulating piece 31 and can drive the regulating piece 31 to be close to or far away from the plate feeding assembly 10, so that the regulating piece 31 can push the plate 1.

As will be readily appreciated, the plate member 1 may be out of position as it enters the sheet feeding assembly 10; for example, referring to fig. 1, the plate member 1 is square, and the edge of the plate member 1 just entering the sheet feeding assembly 10, which is exposed outside the sheet feeding assembly 10, may not be parallel to the direction in which the sheet feeding assembly 10 conveys the plate member 1; at this time, the turnover assembly 20 has difficulty in accurately receiving the plate 1; for this, a leveling assembly 30 is provided outside the sheet feeding assembly 10 upstream of the inverting assembly 20 to adjust the positional state of the plate member 1.

In one embodiment, the alignment assembly 30 may include only one set of alignment member 31 and alignment driving member 32 disposed on one side of the plate feeding assembly 10, and when one plate member 1 passes through, the alignment driving member 32 drives the alignment member 31 to move toward the plate feeding assembly 10, so that the alignment member 31 abuts against one side of the plate member 1 to push the plate member 1 to a side edge thereof parallel to the direction in which the plate member 1 is conveyed by the plate feeding assembly 10. As will be readily appreciated, because the plate member 1 is generally square, when one side is accurately positioned, the other side is accurately positioned.

In another embodiment, the leveling assembly 30 may include two sets of leveling members 31 disposed on two sides of the plate feeding assembly 10, so as to push two sides of the plate 1 exposed outside the plate feeding assembly 10, and further limit the position of the plate 1 on the plate feeding assembly 10 while adjusting the position state of the plate 1, thereby facilitating subsequent processing. At this time, one of the two sets of the regulation members 31 may be fixedly disposed with respect to the blade feeding assembly 10, and the other set of the regulation members 31 may be driven by the regulation driving member 32 to be close to or apart from the fixedly disposed regulation member 31. Or, two sets of regulation pieces 31 all can the activity setting, and when plate 1 passed through, two sets of regulation pieces 31 moved towards each other simultaneously to the both sides of pushing plate 1 for plate 1 both sides are on a parallel with the direction that send piece subassembly 10 to carry plate 1, and simultaneously, plate 1 is certain in the relative position that sends piece subassembly 10.

Wherein, the piece 31 of normalizing can adopt the plate that has certain length along the direction that send piece subassembly 10 to carry plate 1, and its terminal surface that is close to piece subassembly 10 is on a parallel with the direction that send piece subassembly 10 to carry plate 1, so, when normalizing driving piece 32 drive piece 31 is close to piece subassembly 10, the piece 31 of normalizing leans on the plate 1 side, can adjust plate 1. The alignment member 31 may also be an adjustment wheel, specifically referring to fig. 1, which is disposed at the output end of the alignment driving member 32 in the vertical direction (i.e., the direction perpendicular to the paper surface in the drawing), so that the wheel surface of the adjustment wheel faces the sheet feeding assembly 10; the adjusting wheel supports and leans on behind plate 1, not only can adjust plate 1 position state, send piece subassembly 10 not to shut down, continuously drive the in-process that plate 1 carried forward, the adjusting wheel can not rub the side end face of plate 1 yet, and then ensure safe in utilization. Since the regulating wheel abuts only one point of the plate member 1, it is difficult to regulate the extending direction of one side of the plate member 1 when only one regulating wheel is provided, and for this reason, a plurality of regulating wheels may be provided side by side in the direction in which the sheet feeding assembly 10 feeds the plate member 1.

The leveling driver 32 may be a driving member such as an air cylinder or an electric cylinder.

Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. Such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The above description is only an example of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings, or which are directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present application.
