Detailed Description of the Preferred Embodiment

[0023] The utility model provides a punching sheet collection device, comprising a conveying mechanism 1, a transfer mechanism and a collection mechanism. The conveying mechanism 1 conveys the punching sheets formed by the previous process to the transfer mechanism one by one, and the conveying mechanism 1 provides a temporary storage platform and buffer space for the punching sheets. The transfer mechanism can place the punching sheets one by one on the storage rack 11 of the collection mechanism to form a series of storage methods.

[0024] The conveying mechanism 1 may include a conveying frame 12 and a conveyor belt laid on the conveying frame 12. The conveyor belt is equipped with a conveying motor as a transmission power. The conveyor belt may also be equipped with auxiliary devices such as rollers. The conveying mechanism 1 can select a common conveyor belt type conveying mechanism 1. The working state of the conveyor belt of the conveying mechanism 1, such as the start and stop state, can be achieved by controlling the conveying motor.

[0025] The transfer mechanism is installed between the conveying mechanism 1 and the collecting mechanism. The transfer mechanism includes a mounting bracket 2. A guide plate 3 is provided at one end of the mounting bracket 2 close to the conveying mechanism 1, and a movable bracket 4 is provided at one end close to the collecting mechanism. The guide plate 3 is a device composed of two plates. The end of the guide plate 3 close to the collecting mechanism is narrow and faces the position of the clamping plate 6. The side of the guide plate 3 close to the conveying mechanism 1 is wide. After the punching sheet is rushed onto the conveyor belt, it is gradually gathered by the guide plate 3 and driven to correspond to the position of the transfer mechanism.

[0026] The movable bracket 4 is fixed on the installation space, and the movable bracket 4 can change the fixed position as needed to adjust the position of receiving the punching sheet. The movable bracket 4 is equipped with a pneumatic finger 5, and a clamping plate 6 is installed on the pneumatic finger 5. The two clamping plates 6 are combined to form a circular structure, and each clamping plate 6 is provided with a semicircular structure. The pneumatic finger 5 and the working method belong to the prior art. The pneumatic finger 5 can be equipped with a pneumatic valve to control the change of the clamping and loosening working state of the pneumatic finger 5.

[0027] The mounting bracket 2 of the transfer mechanism of the utility model is equipped with a second proximity switch sensor for detecting whether there is a punch on the clamp 6. When there is a punch on the clamp 6, the controller can control the pneumatic finger 5 to open so that the punch falls exactly onto the storage rack 11. The conveying mechanism 1 is equipped with a conveying motor, the pneumatic finger 5 is equipped with a pneumatic valve, and the punch collecting device is equipped with a controller. The controller collects the signal of the second proximity switch sensor and controls the working state of the conveying motor and the pneumatic valve.

[0028] After the punching piece is processed, it falls onto the front end of the conveyor belt. After the conveyor belt moves the punching piece to the tail end, under the guidance of the guiding plate 3 and the action of inertia, the punching piece will fall between the clamping structures formed by two clamping plates 6. The clamping plates 6 are provided with arc-shaped grooves, which can also be adapted to the characteristic that the outer shape of the punching piece is circular. The clamping plates 6 can be replaced with corresponding shapes according to the size and outer shape of the punching piece. After the punching piece falls into the clamping plates 6, the second proximity switch sensor 19 can detect a signal. At this time, the controller can control the conveying motor to pause, and then control the pneumatic finger 5 to open the clamping plates 6, so that the punching piece just falls onto the storage rack 11 below. After this process is completed, the pneumatic conveyor belt conveys the next punching piece again.

[0029] The collection mechanism of the present utility model includes a workbench 7. A turntable 8 is arranged on the workbench 7, and a driving device 9 for driving the turntable 8 to rotate on the workbench 7 is configured; a plurality of positioning holes 10 are arranged on the turntable 8, and a storage rack 11 is movably installed on the positioning holes 10. A plurality of storage racks 11 can be placed on the turntable 8, and a plurality of punching pieces can be stacked on each storage rack 11. When the punching pieces on a storage rack 11 are stacked full, the turntable 8 can be rotated to take them away, and at the same time, the empty storage rack 11 can be moved under the transfer mechanism.

[0030] The driving device 9 of the present utility model may include a driving motor. The driving motor is installed inside the lower part of the workbench 7. A driving gear is installed on the rotating shaft of the driving motor, and the driving gear is engaged with a reduction gear 13 below the turntable 8. The middle part of the turntable 8 is installed on the workbench 7 through a rotating bearing.

[0031] The storage rack 11 of the present utility model includes a baffle. The positioning rod 15 below the baffle is inserted into the positioning hole 10 for fixation. A stringing rod 16 is arranged above the baffle, and the top of the stringing rod is conical. The size of the baffle is larger than that of the positioning hole 10, so that the storage rack 11 will not fall off downward after being placed on the positioning hole 10. The size of the positioning rod below the baffle 14 is slightly smaller than that of the positioning hole 10, realizing the plug-in fixation. The stringing rod can be a cylindrical round rod, and its conical top can also make it more convenient to take and load the punching pieces.

[0032] When the stacked material rack 11 is turned away, there are many punching sheets stacked on it, which has a large weight. When taking out the material rack 11, since the positioning rod of the material rack 11 is inserted into the positioning hole 10, and in order to improve stability, the gap between the positioning rod and the positioning hole 10 is generally small, so that large shaking can be prevented. At this time, when the operator takes out the material rack 11, it is necessary to use a vertical upward force to take it out. If the direction of the force used is not a complete vertical upward force, it will cause jamming, making it more laborious to take out the material rack 11. Therefore, an ejection cylinder is provided on the workbench 7, and the ejection shaft of the ejection cylinder is below the turntable 8 and directly below the positioning hole 10. The ejection shaft of the ejection cylinder ejects the positioning rod from the positioning hole 10 when moving upward; a proximity switch sensor 18 is provided on the side of the ejection cylinder 17, which can determine whether there is a storage rack 11 at this position. After the ejection cylinder is lifted up, it automatically returns to its original position after the storage rack 11 is taken away, so that the next storage rack 11 can be placed in this position.

[0033] Although the specific implementation of the utility model is described in detail in conjunction with the drawings, it should not be understood as limiting the scope of protection of this patent. Within the scope described in the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
