TECHNICAL FIELD

[0001] The application relates to the technical field of blister production, in particular to a blister disc separation system. BACKGROUND

[0002] Blister is a plastic processing technology, which is widely used in plastic packaging, lighting, advertising, decoration and other industries. The main principle of blister is to heat the flat plastic hard sheet to make it soft, then heat-press the plastic through a mold to form a product, and then cut the part connecting the finished product and waste material (such as cutting by moving down the blade) to cut the formed product (blister disc) and the waste material around the formed product, and finally get the formed blister disc.

[0003] When using the above principle to mass-produce blister discs, the above cutting device only cuts the finished product and waste material, so after cutting, the blister disc needs to be taken out from the waste material by manual operation. This operation is not convenient for application in the mass production line of blister discs, because manual operation not only consumes labor but also leads to low production efficiency of the mass production line, so it needs to be improved.

Embodiment

[0033] The following will be described in detail with reference to the accompanying drawings Figures 1-3 The application is further described in detail.

[0034] The embodiment of the application discloses a separating system of a blister tray. Referring to Figure 1 and Figure 2 The separating system of the blister tray comprises a frame 3, a conveying assembly 4 arranged on the frame 3 and used for conveying the cut blister tray 1 and waste 2 along a specified conveying direction (for example, the direction indicated by the arrow B in the figure), a push plate 5, a pushing assembly 6 and a receiving assembly 7 arranged on the frame 3, the push plate 5 is slidably connected to the frame 3, and the sliding direction of the push plate 5 is perpendicular to the specified conveying direction, the pushing assembly 6 is used for driving the push plate 5 to slide and pushing the blister tray 1 in the process of sliding, so that the blister tray 1 is separated from the waste 2, and the receiving assembly 7 is used for receiving and taking the pushed blister tray 1.

[0035] Specifically, referring to Figure 1 and Figure 2 The conveying assembly 4 comprises a third conveying belt 41 rotatably connected to the frame 3, and the third conveying belt 41 is specifically divided into three sections along the width direction of the frame 3, and a gap 42 is reserved between two adjacent sections, the cut blister tray 1 and waste 2 are placed on the third conveying belt 41, and the middle part of the blister tray 1 is located above the gap 42.

[0036] Referring to Figure 1 and Figure 2The jacking assembly 6 includes a rotating rod 61 and a rotating component 62. The rotating rod 61 is rotatably connected to the side wall of the frame 3 and is located below the clearance gap 42. The rotating component 62 may specifically include a first motor 621, a sprocket 622, and a chain 623. The first motor 621 is mounted on the frame 3, and its drive end is connected to one end wall of the rotating rod 61 to drive the rotating rod 61 to rotate. A sprocket 622 is fixedly sleeved on the rotating rod 61 and on each of the two conveyor rollers of the third conveyor belt 41. The chain 623 is sleeved around all the sprockets 622 and is connected to the sprockets 622 for transmission. Therefore, when the first motor 621 is started, it can not only drive the rotating rod 61 to rotate, but also share the same power source with the third conveyor belt 41 to realize the transmission of the third conveyor belt 41.

[0037] Reference Figure 2 and Figure 3 Several connecting rods 611 are fixedly connected to the peripheral wall of the rotating rod 61 near the clearance 42. In this application, the push plate 5 is arranged in a one-to-one correspondence with the connecting rods 611, and the end of the connecting rod 611 away from the rotating rod 61 is hinged to the end wall of the push plate 5; when the rotating rod 61 rotates (as shown in the appendix)... Figure 2 When the top push plate 5 rotates counterclockwise (from the perspective of the rotating rod 61), driven by the rotating rod 61 and the connecting rod 611, it makes a circular motion around the rotating rod 61. The length of the connecting rod 611 satisfies the following condition: when the top push plate 5 moves towards the blister tray 1, the top push plate 5 can pass through the clearance gap 42 and push the blister tray 1 upward, so that the blister tray 1 is separated from the waste material 2. Correspondingly, a waste roller 31 is rotatably connected to the end of the frame 3 and the end of the third conveyor belt 41. The frame 3 is provided with a drive component 32 for driving the waste roller 31 to rotate. Specifically, the drive component 32 can be a motor fixedly connected to one end of the waste roller 31 to drive the waste roller 31 to rotate and reel in the waste material 2.

[0038] Reference Figure 2 The push plate 5 is provided with a leveling member 51, which is used to control the push plate 5 to always be in a horizontal state. In this embodiment, the leveling member 51 can be a counterweight block fixedly connected to the lower surface of the push plate 5. Since the rotating rod 61 rotates slowly and the blister tray 1 itself is made of plastic, its weight is much less than the weight of the counterweight block and the push plate 5. Therefore, when the push plate 5 pushes the blister tray 1, the counterweight block is sufficient to maintain the balance of the push plate 5, so that the push plate 5 in a horizontal state can stably support the blister tray 1, push the blister tray 1 upward while driving the blister tray 1 to move laterally, thereby realizing the transportation of the blister tray 1.

[0039] Reference Figure 2 and Figure 3, the end of the rotating rod 61 away from the first motor 621 penetrates the rack 3 and is provided with a plurality of protrusions 612 along the circumference thereof, the protrusions 612 are provided in one-to-one correspondence with the connecting rods 611, and the protrusion 612 and the straight line connected with the corresponding connecting rod 611 are parallel to the central axis of the rotating rod 61. The rack 3 is further provided with a limiting sheet 33, the limiting sheet 33 and the rack 3 are jointly connected with a supporting spring 34, the supporting spring 34 is parallel to the vertical direction in the extension direction, so that the limiting sheet 33 can be lifted in the vertical direction. The limiting sheet 33 is located above the third conveying belt 41, and a gap only allowing the waste 2 to pass through is reserved between the limiting sheet 33 and the third conveying belt 41, and the lower surface of the limiting sheet 33 is rotationally connected with a butt joint rod 35.

[0040] With reference to Figure 3 , one end of the limiting sheet 33 extends to the rotating path of the protrusion 612, so that the protrusion 612 can press against the limiting sheet 33 during rotation, thereby causing the limiting sheet 33 to move downward in the direction close to the third conveying belt 41, the butt joint rod 35 moves downward to abut against the waste 2, separates from the waste 2, blocks the waste 2, and avoids the waste 2 from moving upward together with the plastic suction tray 1, at this time the supporting spring 34 is in a compressed state, and when the protrusion 612 rotates to be separated from the limiting sheet 33, the limiting sheet 33 moves upward to reset under the elastic force of the supporting spring 34.

[0041] With reference to Figure 2 and Figure 3 , the receiving assembly 7 comprises a first conveying belt 71, the first conveying belt 71 is drivingly connected to the end of the rack 3 and is located on the track of the movement of the plastic suction tray 1; the surface of the push plate 5 towards the plastic suction tray 1 is further provided with a second conveying belt 52, the conveying direction of the second conveying belt 52 is parallel to the specified conveying direction; as can be seen from the above structure, the push plate 5 can not only push the plastic suction tray 1 upward to separate the plastic suction tray 1 from the waste 2, but also can transport the plastic suction tray 1 in the direction close to the first conveying belt 71 while the push plate 5 itself does the circular motion, so as to cooperate with the second conveying belt 52 to make the end of the plastic suction tray 1 be received by the first conveying belt 71, and then the plastic suction tray 1 is completely moved to the first conveying belt 71 by the first conveying belt 71.

[0042] With reference to Figure 2 and Figure 3 , one end of the rack 3 is provided with a support table 731, the receiving assembly 7 further comprises a receiving table 72 and a lifting piece 73, the lifting piece 73 comprises a second motor 732, a lead screw 733 and a guide rod 734; the guide rod 734 is fixedly connected to the support table 731 and penetrates the receiving table 72, the lead screw 733 is rotationally connected to the support table 731, and the receiving table 72 is threadedly sleeved on the lead screw 733; the second motor 732 is installed on the support table 731, and the driving end of the second motor 732 is connected to the lower end of the lead screw 733; the support table 731 is fixedly connected with a limiting plate 74 on the top, and the limiting plate 74 encloses a receiving space 741 for the plastic suction tray 1 to be inserted.

[0043] With reference to Figure 2 and Figure 3 , the receiving assembly 7 further comprises a stacking detection module 735, a control module 736 and a pushing cylinder 737, the stacking detection module 735, the pushing cylinder 737 and the second motor 732 are electrically connected to the control module 736; the control module 736 can be a PLC controller, and the control module 736 is used to control the second motor 732 to rotate a specified number of turns every specified time interval.

[0044] The stacking detection module 735 can be a distance measuring sensor embedded in the bottom wall of the support table 731, and the detection end of the stacking detection module 735 faces the lower surface of the receiving table 72, so as to detect the distance between the two and transmit the detected distance value to the control module 736. The control module 736 can be a PLC controller, the pushing cylinder 737 is installed on one side of the receiving table 72, and the pushing cylinder 737 drive shaft is fixedly connected with a pushing rod 738. When the receiving table 72 moves downward to a specified height, that is, the distance value detected by the stacking detection module 735 is equal to the preset distance value, at this time the blister tray 1 on the receiving table 72 is just located in the extension path of the pushing cylinder 737 drive shaft, at this time the control module 736 controls the second motor 732 to stop and controls the pushing cylinder 737 to start, so that the pushing cylinder 737 drive shaft extends and retracts for one round trip and then stops, and then the second motor 732 is started to make the receiving table 72 move upward to the initial height, and then the second motor 732 is controlled to rotate a specified number of turns every specified time interval.

[0045] The implementation principle of the blister tray separation system according to an embodiment of the present application is as follows: the cut blister tray 1 and the waste material 2 are conveyed to above the rotating rod 61 by the third conveying belt 41, the push plate 5 penetrates through the clearance 42 during the rotation of the rotating rod 61 and pushes the blister tray 1, at the same time, the protrusion 612 presses the limiting piece 33, so that the abutting rod 35 on the limiting piece 33 presses the waste material 2, realizing the separation of the blister tray 1 and the waste material 2, the blister tray 1 moves to the upper surface of the first conveying belt 71 under the transmission of the push plate 5 and the second conveying belt 52 on the surface of the push plate 5, and the blister tray 1 is received by the first conveying belt 71, so that the blister tray 1 is completely moved to the first conveying belt 71, and then the blister tray 1 is conveyed to the receiving table 72 by the first conveying belt 71.

[0046] The limiting plate 74 limits the blister tray 1 during the process of being conveyed to the receiving table 72. In addition, the control module 736 drives the receiving table 72 to move downward by a specified distance every specified time interval, so that the upper surface of the receiving table 72 always keeps flush with the first conveying belt 71, and the specified time interval is just the time interval of the adjacent two blister trays 1 being conveyed above the receiving table 72. When the distance value detected by the stacking detection module 735 is equal to the preset distance value, that is, the receiving table 72 is moved to the specified height, the control module 736 controls the pushing cylinder 737 to start, so that the pushing cylinder 737 drives the shaft to extend and retract back and forth and then stop. At this time, all the blister trays 1 on the receiving table 72 are pushed away from the receiving table 72 by the pushing rod 738. Then the control module 736 controls the second motor 732 to start, so that the receiving table 72 moves upward to the initial height. Finally, the control module 736 starts again to control the second motor 732 to rotate by a specified number of turns every specified time interval, so as to realize the intermittent downward movement of the receiving table 72 again.
