The cut pieces 11 are placed in the limiting stopper 10, and the limiting stopper 10 can play a preliminary positioning role in the placement position and angle of the cut pieces 11, so that the stacked cut pieces 11 have a consistent placement. Further, the plurality of limiting stopper bars 10 are distributed according to the specific shape and size of the cut pieces 11. In principle, the number of limiting stopper bars 10 is as small as possible under the premise of effectively limiting the cut pieces 11. There is a gap between the outer periphery of the limiting stopper bar 10 and the cut piece lifting plate 5, so that the lifting and lowering of the cut piece lifting plate 5 is not interfered.

[0034] Furthermore, the cut piece placement assembly includes a motor mounting plate bracket 2, a cut piece placement lifting motor 3 and a cut piece lifting motor mounting plate 4. The motor mounting plate bracket 2 is connected to the bottom of the cut piece lifting motor mounting plate 4, and the two together form a support frame of the cut piece placement assembly. The upper end of the support frame is provided with a cut piece lifting plate 5, and the lower end is provided with a cut piece placement lifting motor 3. One end of the limit stopper 10 passes through the cut piece lifting plate 5 and is connected to the cut piece lifting motor mounting plate 4. The input end of the cut piece placement lifting unit is connected to the cut piece placement lifting motor 3, and the output end is connected to the cut piece lifting plate 5. The cut piece placement lifting motor 3 works, driving the cut piece placement lifting unit to drive the cut piece lifting plate 5 to move up and down, so as to make the cut piece material 11 approach or move away from the cut piece picking assembly. Driven by the cut piece placement lifting motor 3, the cut piece lifting plate 5 moves up and approaches the cut piece picking assembly, so that the cut piece picking assembly can pick up the cut piece material 11 located at the top layer in the storage space and send it to the next process. Driven by the cut piece placement lifting motor 3, the cut piece lifting plate 5 moves downward and away from the cut piece picking assembly, so as to facilitate the placement of the stacked cut piece material 11 through the storage space and the movement of the cut piece picking assembly.

[0035] The support frame of the cut piece placement assembly is connected to the base 1 through the motor mounting plate bracket 2, and is used to stably connect the cut piece placement assembly to the base 1.

[0036] In order to reduce the position deviation of the cutting piece lifting plate 5 during the movement process and avoid affecting the positioning of the cutting piece material 11 by the limit stopper 10, the cutting piece placing assembly includes a vertically arranged first guide column 8, one end of which passes through the cutting piece lifting plate 5 and is connected to the cutting piece lifting motor mounting plate 4, so as to make the cutting piece lifting plate 5 move along the direction of the first guide column 8 to reduce the position deviation. The first guide column 8 is sleeved with a guide column sliding sleeve 7 on one side of the cutting piece lifting plate 5, and the guide column sliding sleeve 7 and the first guide column 8 are used in combination to realize the guiding function of the cutting piece lifting plate 5.

The cut piece position adjustment component includes a position adjustment part, a reference plate 28 and a mounting plate 29. The reference plate 28 and the position adjustment part are arranged on the mounting plate 29. The position adjustment part can move toward the reference plate 28. The reference plate 28 forms a reference surface 27 at one end of the position adjustment part. The position adjustment part and the reference surface 27 form a limiting circle for placing the cut piece material 11 and adjusting the position of the cut piece material 11. According to the appearance of the cut piece material 11 and the subsequent action requirements, the contour of the reference surface 27 and the position of the position adjustment part are set, so that one side of the cut piece material 11 is in contact with the reference surface 27, and the formed limiting circle meets the required position placement requirements of the cut piece material 11, thereby realizing secondary positioning and placement of the cut piece material 11.

[0039] The position adjustment unit is connected to the mounting plate 29 via the cylinder bracket 25, and is used to mount the position adjustment unit on the mounting plate 29. As an embodiment of the present invention, Fig. 9 As shown, the position adjustment part includes two first gas pipelines 21, a side-pushing piece cylinder 22 and a piece push plate 23. The two first gas pipelines 21 are respectively an air inlet pipeline and an air outlet pipeline. The end of the side-pushing piece cylinder 22 away from the reference plane 27 is connected to the gas pipeline, and the end facing the reference plane 27 is connected to the piece push plate 23. Through the coordination of the air inlet and air outlet of the first gas pipeline 21, the push rod of the side-pushing piece cylinder 22 drives the piece push plate 23 to move forward and backward. Specifically, the piece push plate 23 and the reference plane 27 form a limiting circle. The top layer of the piece material 11 located in the storage space is the top layer of the piece 13. The top layer of the piece 13 is taken by the piece picking assembly and placed on the mounting plate 29. At this time, the push rod of the side-pushing piece cylinder 22 is in a recovered state. Under the action of the first gas pipeline 21, the push rod of the side-pushing cutting piece cylinder 22 begins to move toward the reference plane 27, and adjusts the position of the top-layer cutting piece 13 by the movement and pushing action of the side-pushing cutting piece cylinder 22 until the top-layer cutting piece 13 is placed in a position that meets the requirements. After the position placement requirements are met, the push rod of the side-pushing cutting piece cylinder 22 moves backward by a displacement L for recovery. Usually, the displacement L is ≥ 5 mm. The specific value of the displacement L is based on the standard of meeting the safety and convenience of on-site production.

[0040] The position adjustment part formed by the first gas pipeline 21, the side-pushing cutting piece cylinder 22 and the cutting piece pushing plate 23 constitutes a power component for pushing and adjusting the position of the cutting piece. The number of the position adjustment parts is M. The value and installation position of M are determined according to the actual situation such as the shape and size of the cutting piece material 11. Under normal circumstances, 2≤M≤6.

One side of the second gas pipeline 17 is connected to the gas source, and the other side is connected to the joint 15. The gas in the second gas pipeline 17 provides airflow suction to the joint 15, thereby adsorbing the cut piece material 11 and reducing the deformation of the cut piece material 11 caused by picking up the cut piece material 11.

[0046] The position of the top sheet 13 in the storage space formed by the limiting stopper 10 and the sheet lifting plate 5 is marked as A, and the position of the top sheet 13 in the limiting circle surrounded by the position adjustment part and the reference surface 27 is marked as B. Further, the distance from the A position to the joint 15 is almost the same as the distance from the B position to the joint 15, so that the joint 15 can move the top sheet 13 from the A position to the B position only after horizontal movement. Further, the adjustable support plate 19 is a telescopic structure, which can be adjusted according to actual needs. Preferably, the length of the adjustable support plate 19 is such that when the picking part moves to the position of the sheet placement assembly, the joint 15 can be located directly above the A position, so that the joint 15 can pick up the top sheet 13 in the storage space.

[0050] As an embodiment of the present invention, a first position sensor 40 is provided on the top of the first guide column 8 for detecting and sensing the position of the top layer of the cutting piece 13. When the first position sensor 40 senses the top layer of the cutting piece 13 during the ascending process of the cutting piece placement lifting unit, the cutting piece placement lifting motor 3 stops running, the taking unit starts working, the connector 15 takes the top layer of the cutting piece 13, and performs subsequent operations.

When the connection seat 18 moves to the A position, when the second position sensor 43 detects the connection seat 18, the connection seat 18 stops moving, so that the connector 15 can accurately position the top cut piece 13 in the storage space. When the connection seat 18 moves to the B position, when the third position sensor 44 detects the connection seat 18, the connection seat 18 stops moving, so that the connector 15 can accurately position the top cut piece 13 in the limit circle.

[0053] The automatic placement device for cut pieces also includes a control box 31, which is used to receive and process signals and execute a control system when the automatic placement device for cut pieces is running, thereby realizing an automated production process in which the automatic placement device for cut pieces takes and accurately places the top cut pieces 13.

[0054] The placing method of the automatic placing device for cut pieces of materials of the utility model comprises the following steps:

[0055] S1. Cut pieces of material 11 provided;

[0056] A plurality of cut pieces 11 are stacked together and placed in a storage space formed by the limiting stopper 10 and the cut piece lifting plate 5 , and the cut piece 11 located on the uppermost layer is a top layer cut piece 13 .

[0057] Specifically, the power supply is turned on, and the cut piece placement lifting motor 3 starts to rotate, and through the joint action of the threaded sleeve 6, the threaded screw 9 and the cut piece lifting plate 5, the cut piece material 11 is driven to move upward as a whole along with the cut piece lifting plate 5, as shown in FIG. Figures 1-2 shown.

[0058] When the top layer of cutting piece 13 enters the sensing area of ​​the first position sensor 40, the first position sensor 40 sends a sensing signal to the control box 31. The control box 31 receives the signal and outputs a corresponding signal to the cutting piece placement lifting motor 3 according to the designed corresponding program. The cutting piece placement lifting motor 3 stops moving, and the cutting piece material 11 stops moving upward as a whole.

[0059] S2. Take the top sheet 13;

[0060] Specifically, the initial position of the connector 15 is directly above the storage space. When the first position sensor 40 senses the top sheet 13 and the top sheet 13 is in a stationary state, the control box 31 outputs a take command, the gas source is connected to the second gas pipeline 17, and the air flow in the second gas pipeline 17 acts on the connector 15, and the connector 15 generates a take action or negative pressure suction, thereby taking the top sheet 13.

[0062] Specifically, the second motor 30 is started, and the lifting screw 33, the thread 35 and the second motor lifting connecting plate 34 work together to lift the picking component support plate 14 and the joint 15 to move upward. Correspondingly, the top layer of the cutting piece 13 also rises and reaches the sensing position area of ​​the displacement upper sensor 41. The displacement upper sensor 41 senses the picking component support plate 14 and sends a signal to the control box 31. The control box 31 receives the signal of the displacement upper sensor 41, and outputs the corresponding control signal to the second motor 30 according to the designed corresponding program. The second motor 30 stops rotating after receiving the signal, and the cutting piece picking component stops moving upward as a whole.

[0063] S4. The cutting piece taking assembly drives the top cutting piece 13 to move horizontally to position B;

[0064] Specifically, the first motor 16 is started, driving the cut piece picking assembly located on the first motor track to move horizontally from position A to position B, and the top cut piece 13 moves synchronously with the joint 15, such as Figure 4 shown.

[0065] The connector 15 absorbs the top layer of the cutting piece 13 and reaches the sensing position area of ​​the third position sensor 44. The third position sensor 44 senses the signal of the connecting seat 18, and the third position sensor 44 sends a signal to the control box 31. The control box 31 receives the signal of the third position sensor 44, and outputs a corresponding control signal to the first motor 16 according to the designed corresponding program. The first motor 16 stops rotating after receiving the signal, and the connector 15 brings the top layer of the cutting piece 13 to the top of the reference surface 27.

[0066] S5. The cutting piece taking component drives the top cutting piece 13 to move downward;

[0067] Specifically, the second motor 30 is started and performs a rotation opposite to step S3. The lifting screw 33, the thread 35 and the second motor lifting connecting plate 34 work together to drive the picking component support plate 14 and the joint 15 to move downward. Correspondingly, the top layer of the cutting piece 13 also moves downward to reach the sensing position area of ​​the displacement sensor 42. The displacement sensor 42 senses the signal of the picking component support plate 14 and sends a signal to the control box 31. The control box 31 receives the signal of the displacement sensor 42 and outputs the corresponding control signal to the second motor 30 according to the designed corresponding program. After receiving the signal, the second motor 30 stops rotating, and the joint 15 and the top layer of the cutting piece 13 stop moving downward as a whole. At this time, the distance H between the upper end surface of the picking component support plate 14 and the bottom of the mounting plate 29 is 0≤H≤5mm. In addition, the picking component support plate 14 cannot interfere with the reference surface 27 and the cutting piece push plate 23. Figure 5 shown.

[0068] S6. The top sheet 13 is placed on the mounting plate 29;

[0069] Specifically, the control box 31 outputs a signal, the air source is closed, and the connector 15 loses its force on the top sheet 13 . Under the action of gravity, the top sheet 13 and the connector 15 separate and fall on the upper end surface of the mounting plate 29 and are located at the reference surface 27 .

[0070] S7. The cutting piece taking component rises;

[0071] Specifically, the control box 31 outputs a signal to perform the same ascending action as in step S3, so as to achieve the upward displacement of the cut piece picking assembly. Figure 6 However, in step S7, the cut piece taking assembly has been separated from the top cut piece 13, and only the cut piece taking assembly rises.

[0072] S8. The cut piece picking component moves horizontally to position A;

[0073] Specifically, the first motor 16 is started, driving the cut piece picking assembly located on the first motor track to move horizontally from position B to position A, and the joint 15 reaches the sensing position area of ​​the second position sensor 43. The second position sensor 43 senses the signal of the connecting seat 18, and the second position sensor 43 sends a signal to the control box 31. The control box 31 receives the signal of the second position sensor 43, and outputs a corresponding control signal to the first motor 16 according to the designed corresponding program. The first motor 16 stops rotating after receiving the signal, so that the joint 15 is located at position A and is located on the upper side of the storage space, as shown in FIG. Figure 7 shown.

[0074] S9. Adjust the position of the top sheet 13;

[0075] Specifically, the top sheet 13 falls on the upper end surface of the mounting plate 29, and the control box 31 outputs a signal to start the airflow in the first gas pipeline 21, pushing the push rod of the side-pushing sheet cylinder 22 to move in the direction of the top sheet 13, thereby driving the sheet push plate 23 to move toward the top sheet 13, and after contacting the side edge of the top sheet 13, the top sheet 13 is pushed sideways, pushing the top sheet 13 to move in the direction of the side thrust. Through the single or multiple movement adjustments of the side-pushing sheet cylinder 22, and the mutual cooperation with the reference surface 27, the top sheet 13 enters the limit circle, realizing the production requirements for the precise placement of the top sheet 13, such as Figure 8 shown.

[0076] The automatic placement device for cut pieces of materials of the utility model can realize accurate placement of cut pieces of materials 11, and the placement positions of batch cut pieces of materials 11 have consistency and good stability, solving the position differences of individual cut pieces of materials 11 that cannot be avoided by manual placement. The device has a high degree of automation and a simple structure, which is easy to promote and apply.
