Description

Technical Field

[0001] The utility model relates to the technical field of conveying, in particular to a linkage transfer unit for non-flat-bottom packaging bottles. Background Art

[0002] The packaging of cream cosmetics is generally divided into two parts, one is the internal packaging bottle, and the other is the external packaging box. The lower part of some packaging bottles is an ellipsoidal structure. If placed naturally, the bottle mouth will face sideways because there is no flat surface at the bottom. However, in order to realize the filling of cream cosmetics, the packaging bottle must be opened upward, so a cup holder is needed to keep its opening upward. When the packaging bottle is put into the packaging box, the packaging bottle is mostly placed horizontally and pushed into the packaging box from the side to complete the outer packaging. Therefore, the filling of this type of packaging bottle has a conveyor line for conveying the cup holder and the packaging bottle as a whole, and the external packaging has a separate conveyor line for conveying the packaging bottle, and a transfer device is required to move between the two. Here, the packaging bottle must not only switch the conveyor line, but also complete the turn from vertical to horizontal, otherwise the packaging bottle cannot be placed in a position that is easy to box.

[0003] Chinese patent CN115108074A discloses a horizontal and vertical automatic cartoning machine, which can use a robot to take the vertical packaging bottles from the packaging bottle conveyor belt, and then place them horizontally into the packaging box. The packaging bottles here have a bottom plane and a top plane. Because the bottom plane allows the packaging bottles to stand upright, there is no need to use a cup holder during transportation. The top plane facilitates suction, so it is relatively simple to transfer with a robot. However, for products whose bottom structure cannot be upright, it is difficult to control the robot's movements, and it is difficult to ensure that many packaging bottles can be transferred at one time. The packaging bottles are easy to fall, so they can only be transferred one by one, and the work efficiency is not high.

[0004] Therefore, it is necessary to provide a new transfer device structure to solve the above problems. Summary of the invention

[0005] The main purpose of the utility model is to provide a linkage transfer unit for non-flat bottom packaging bottles, which can change the packaging bottles with complex bottom surfaces from a vertical state on a cup holder to a horizontal state for box packing.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions: a linkage transfer unit for non-flat-bottom packaging bottles, comprising a first conveying section, a second conveying section, a bottle grabbing mechanism and a transfer mechanism;

[0007] The first conveying section and the second conveying section are arranged in parallel and the conveying direction is along the X-axis. The bottle grabbing mechanism is arranged above the first conveying section. The first conveying section and the second conveying section are located on both sides of the transfer mechanism in the Y direction. The packaging bottle is placed on the cup holder in an upright posture. A stop block is provided at the outlet of the first conveying section to block the cup holder under the bottle grabbing mechanism. The second conveying section is provided with a pair of spacer bars to keep the packaging bottle in a horizontal posture.

[0008] The bottle grabbing mechanism comprises a bracket, a lifting mechanism disposed on the upper part of the bracket, a connecting beam driven by the lifting mechanism, and a clamping claw disposed on the connecting beam, wherein the clamping claw grabs the packaging bottle from both sides of the X direction;

[0009] The transfer mechanism includes a fixed seat, a servo motor, a first rotating shaft, a rotating arm, a second rotating shaft and a suction block. The first rotating shaft is rotatably arranged in the middle of the fixed seat and is driven by the servo motor to rotate. The axis of the first rotating shaft and the axis of the second rotating shaft are parallel to each other and along the X direction. The suction block is connected to the second rotating shaft. The second rotating shaft is rotatably connected to the free end of the rotating arm. The rotating arm is fixedly connected to the first rotating shaft. A first synchronous wheel that is coaxial with the first rotating shaft is fixed to one side of the fixed seat. A second synchronous wheel is fixed to the second rotating shaft. The first synchronous wheel and the second synchronous wheel are linked by a first synchronous belt.

[0010] Specifically, there are multiple clamps and they are arranged side by side on the connecting beam along the X-axis, and the second rotating shaft is provided with suction blocks equal in number to the clamps and they are arranged side by side on the second rotating shaft along the X-axis.

[0011] Furthermore, the suction block has a contoured groove that fits the side shape of the packaging bottle, and the inner wall of the contoured groove is provided with a plurality of suction holes.

[0012] Furthermore, the auxiliary blocking mechanism is arranged in the middle of the bracket and is located on the opposite side of the suction block to the bottle picking position. The auxiliary blocking mechanism includes a first side push driving member and a blocking block driven by the first side push driving member to extend and retract along the Y direction, and the blocking block faces the suction block.

[0013] Furthermore, the first conveying section includes a cup-input line and a cup-returning line in opposite conveying directions, each of the cup-input line and the cup-returning line can only accommodate the width of one cup holder, the cup-returning line is located between the cup-input line and the transfer mechanism and is directly below the clamping claw, a cup-pushing mechanism is provided at the lower part of the bracket, the cup-pushing mechanism includes a second side-pushing driving member and a cup-pushing block that is driven by the second side-pushing driving member to extend and retract along the Y direction, the cup-pushing block pushes a row of cup holders on the cup-input line onto the cup-returning line, and the cup-returning line is provided with side guard bars on the opposite side of the cup-pushing mechanism.

[0014] Furthermore, a rotating arm is provided at each end of the first rotating shaft, the second rotating shaft is connected to the free ends of the two rotating arms, the two rotating arms are divided into a first rotating arm close to the first synchronous wheel and a second rotating arm far away from the first synchronous wheel, a protrusion is provided on one side of the first rotating arm, a long hole is provided on the protrusion, a tension adjusting wheel is provided on the long hole, and the tension adjusting wheel is pressed on the outside of the first synchronous belt.

[0015] Specifically, the servo motor is arranged at the lower part of the fixing seat, the servo motor drives the third synchronous wheel, the fourth synchronous wheel is fixed on the first rotating shaft, and the third synchronous wheel and the fourth synchronous wheel are linked by a second synchronous belt.

[0016] Specifically, it also includes a casing, which surrounds the bottle grabbing mechanism and the transfer mechanism.

[0017] The beneficial effects of the technical solution of the utility model are:

[0018] The linkage transfer device can first use the bottle grabbing mechanism to grab the upright packaging bottle from the cup holder, and then rotate the transfer mechanism to a horizontal state and place it on the second conveying section. When the servo motor drives the first rotating shaft to rotate, the rotating arm will swing in one direction, but because the first synchronous wheel is fixed, the second rotating shaft will move in the opposite direction under the action of the first synchronous belt. When the first synchronous wheel and the second synchronous wheel have a suitable transmission ratio, the outer end of the rotating arm rotates from the side close to the first conveying section to the side close to the second conveying section, and the suction block rotates from the horizontal direction to the vertical direction. In this way, the packaging bottle can complete the replacement of the conveyor line and meet the steering requirements, which is suitable for the boxing of non-flat-bottom packaging bottles.

[0033] The utility model is further described in detail below in conjunction with specific embodiments.

[0034] Example:

[0035] like Figure 1 and Figure 2 As shown, a linkage transfer unit 1 of the utility model comprises a first conveying section 11 , a second conveying section 12 , a bottle grabbing mechanism 13 , a transfer mechanism 14 , an auxiliary blocking mechanism 15 , a cup pushing mechanism 16 and a housing 17 .

[0036] like Figure 1 and Figure 2 As shown, the first conveying section 11 and the second conveying section 12 are arranged in parallel and the conveying direction is along the X-axis. The bottle grabbing mechanism 13 is arranged above the first conveying section 11. The first conveying section 11 and the second conveying section 12 are located on both sides of the transfer mechanism 14 in the Y direction. The packaging bottle 2 is placed on the cup holder 3 in an upright posture. A blocking block 111 is provided at the outlet of the first conveying section 11 to block the cup holder 3 under the bottle grabbing mechanism 13. The second conveying section 12 is provided with a pair of baffle bars 121 to keep the packaging bottle 2 in a horizontal posture.

[0037] The first conveying section 11 is part of the bottle filling conveyor line. During the process of filling the bottle 2, the cup holder 3 is used as a carrier to ensure that the bottle mouth is facing upward, so the bottle 2 is in an upright position. The second conveying section 12 is part of the bottle boxing conveyor line. The bottle 2 is transported in a horizontal position to complete the boxing process, so there is a barrier strip 121 on the second conveying section 12 to keep the bottle 2 in a horizontal position. When the bottle 2 is transferred from the first conveying section 11 to the second conveying section 12, it needs to be lifted by the bottle grabbing mechanism 13 first, and then flipped and placed by the transfer mechanism 14.

[0038] like Figure 2 As shown, the bottle grabbing mechanism 13 includes a bracket 131, a lifting mechanism 132 disposed on the upper part of the bracket 131, a connecting beam 133 driven by the lifting mechanism 132, and a clamping claw 134 disposed on the connecting beam 133, and the clamping claw 134 grabs the packaging bottle 2 from both sides of the X direction.

[0039] Because the bottle 2 cannot be rotated directly when it is still in the cup holder 3, it is necessary to use the bottle gripping mechanism 13 to first clamp it to a certain height, so as to completely separate it from the cup holder 3, and then let the transfer mechanism 14 suck it from the side and swing it downward 90 degrees, so as to achieve a horizontal posture. The specific action of clamping is: the lifting mechanism 132 drives the clamping claws 134 opened to both sides to move to both sides of the bottle 2. Then the clamping claws 134 clamp the bottle 2 from both sides in the X direction, and the lifting mechanism 132 drives the clamping claws 134 to rise, so that the bottle 2 is separated from the cup holder 3.

[0040] like Figure 2 As shown, the first conveying section 11 includes a cup inlet line 112 and a cup return line 113 in opposite conveying directions. The cup inlet line 112 and the cup return line 113 only accommodate the width of one cup holder 3. The cup return line 113 is located between the cup inlet line 112 and the transfer mechanism 14 and is directly below the clamping claw 133. A cup pushing mechanism 16 is provided at the lower part of the bracket 131. The cup pushing mechanism 16 includes a second side pushing driving member 161 and a cup pushing block 162 that is driven by the second side pushing driving member 161 to extend and retract along the Y direction. The cup pushing block 162 pushes a row of cup holders 3 on the cup inlet line 112 onto the cup return line 113. The cup return line 113 is provided with a side blocking bar 114 on the opposite side of the cup pushing mechanism.

[0041] The cup holder 3 with the packaged bottle 2 is conveyed along the cup inlet line 112 and finally blocked in front of the stopper 111. At this time, there is an empty cup holder 3 on the adjacent cup return line 113. When the cup return line 113 moves the empty cup holder 3 away from directly below the clamping jaw 133, the cup return line 113 stops, and the cup pusher 162 pushes several cup holders 3 with the packaged bottle 2 from the cup inlet line 112 to the cup return line 113 and then is blocked by the side block 114. At this time, the cup holder 3 with the packaged bottle 2 is located below the clamping jaw 133, and the clamping jaw 133 can be lowered to move the packaged bottle 2 out of the cup holder 3. In actual application, the first conveying section 11 may not adopt the form of the cup inlet line 112 and the cup return line 113 being arranged side by side, but may be moved in and out in one direction, and the empty cup holder 3 is sent back to the bottle filling line at other positions.

[0042] like Figure 2 and Figure 3 As shown, the transfer mechanism 14 includes a fixed seat 141, a servo motor 142, a first rotating shaft 143, rotating arms (first rotating arm 144a, second rotating arm 144b), a second rotating shaft 145 and a suction block 146. The first rotating shaft is rotatably arranged in the middle of the fixed seat and is rotated by the servo motor. The axis of the first rotating shaft and the axis of the second rotating shaft are parallel to each other and along the X direction. The suction block is connected to the second rotating shaft. The second rotating shaft is rotatably connected to the free end of the rotating arm. The rotating arm is fixedly connected to the first rotating shaft 143. A first synchronous wheel 147 that is coaxial with the first rotating shaft 143 is fixed to one side of the fixed seat 141. A second synchronous wheel 1451 is fixed to the second rotating shaft 145. The first synchronous wheel 147 and the second synchronous wheel 1451 are linked by a first synchronous belt 148a.

[0043] When the servo motor 142 drives the first rotating shaft 143 to rotate, the rotating arm will swing in one direction, but because the first synchronous wheel 147 is fixed, the second rotating shaft 145 will move in the opposite direction under the action of the first synchronous belt 148a. When the first synchronous wheel 147 and the second synchronous wheel 1451 have a suitable transmission ratio, when the outer end of the rotating arm rotates from the side close to the first conveying section 11 to the side close to the second conveying section 12, the suction block 146 rotates from the horizontal direction to the vertical direction, so that the packaging bottle 2 can complete the replacement of the conveyor line and meet the steering requirements, which is suitable for the boxing work of non-flat-bottom packaging bottles.

[0044] like Figure 2 As shown, there are four clamping jaws 134 arranged side by side on the connecting beam 133 along the X axis, and four suction blocks 146 are arranged on the second rotating shaft and arranged side by side on the second rotating shaft along the X axis. The number of suction blocks 146 can be equal to the number of clamping jaws 133, and is not limited to four.

[0045] In this way, the multiple clamping claws 134 can clamp multiple packaging bottles 2 at one time, and then the multiple suction blocks 146 can transfer the multiple packaging bottles 2 clamped by the clamping claws 134 together, so a higher transfer efficiency is achieved with a relatively simple mechanism.

[0046] like Figure 2 As shown, the suction block 146 has a contoured groove 1461 that fits the side profile of the packaging bottle 2, and the inner wall of the contoured groove 1461 is provided with a plurality of suction holes.

[0047] In order to generate a sufficiently large suction force on the side of the packaging bottle 2 to prevent it from falling during transfer, the suction surface of the suction block 146 needs to fit the shape of the packaging bottle 2, so the suction block 146 needs to be designed with a contoured groove 1461 so that the suction surface fits the Y side of the packaging bottle 2 without interfering with the position of the clamp 133.

[0048] like Figure 2 As shown, the auxiliary blocking mechanism 15 is arranged in the middle of the bracket 131 and is located on the opposite side of the bottle taking position of the suction block 146. The auxiliary blocking mechanism 15 includes a first side pushing drive member 151 and a blocking block 152 driven by the first side pushing drive member 151, and the blocking block 152 faces the suction block 146.

[0049] When the suction block 146 contacts the bottle 2, it will apply a Y-direction thrust to the side of the bottle 2. Since the bottle 2 is still clamped by the clamp 133, this thrust will easily knock the bottle 2 crooked, and the suction block 146 may not be able to suck the bottle 2. At this time, the clamp 133 is loosened, which may cause the bottle 2 to fall. In order to avoid this problem, when the bottle 2 is clamped, the first side push drive 151 will drive the blocking block 152 to stick to the back of the bottle 2, so that the suction block 146 can fully contact the side wall of the bottle 2 and adsorb correctly, reducing the risk of the bottle 2 falling.

[0050] like Figure 2 As shown, the servo motor 142 is disposed at the lower part of the fixing seat 141 , and the servo motor 142 drives the third synchronous wheel 1421 . A fourth synchronous wheel 1431 is fixed on the first rotating shaft 143 , and the third synchronous wheel 1421 and the fourth synchronous wheel 1431 are linked via a second synchronous belt 148 b.

[0051] In this case, the servo motor 142 does not need to be arranged on one side of the fixing seat 141, but is hidden and arranged at the lower part of the fixing seat 141. In addition, this also reduces the wear problem caused by the poor coaxiality between the servo motor 142 and the first rotating shaft 143.

[0052] like Figure 2As shown, a rotating arm is provided at each end of the first rotating shaft 143, and the second rotating shaft 145 is connected to the free ends of the two rotating arms. The two rotating arms are divided into a first rotating arm 144a close to the first synchronous wheel 147 and a second rotating arm 144b away from the first synchronous wheel 147. A protrusion 1441 is provided on one side of the first rotating arm 144a, and a long hole 1442 is provided on the protrusion 1441. A tension adjusting wheel 149 is provided on the long hole 1442, and the tension adjusting wheel 149 is pressed on the outer side of the first synchronous belt 147.

[0053] The first rotating arm 144a and the second rotating arm 144b keep moving synchronously, which can ensure that the second rotating shaft 145 is along the X direction, and ensure that the suction blocks 146 arranged side by side can correctly suck the packaging bottles 2.

[0054] like Figure 1 As shown, the housing 17 surrounds the bottle grabbing mechanism 13 and the transfer mechanism 14 .

[0055] The bottle grabbing mechanism 13 and the transfer mechanism 14 both include many parts that can move relative to each other. In order to prevent others from damaging the parts and the moving parts from injuring the staff, these two mechanisms need to be protected by the housing 17.

[0056] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
