As shown in FIGS. 1 to 4 , a tool handle feeding mechanism comprises a stacking mechanism 1, wherein the stacking mechanism 1 comprises a plurality of bins 5 and a rotating base 4, wherein the plurality of bins 5 are fixedly arranged on the rotating base 4, and the rotating base 4 is rotatably arranged on a machine platform;

A positioning mechanism 3 is arranged on one side of the stacking mechanism 1, and a clamping position for placing a tool handle blank is provided on the positioning mechanism 3;

The material taking mechanism 2 sucks the tool handle blank from the material bin 5 and places the tool handle blank at the clamping position.

In this embodiment, after the stacking mechanism 1 stacks the tool handle blanks, during the operation of the equipment, the picking mechanism 2 absorbs the tool handle blanks from the silo 5 in the stacking mechanism 1. When the material in the area where the picking mechanism 2 absorbs the tool handle blanks is used up, the stacking mechanism 1 can be rotated to move another silo 5 storing the tool handle blanks to the position of the working area of the picking mechanism 2, thereby realizing non-stop operation during the operation. When the number of silos 5 set in the stacking mechanism 1 is 2 or more, other silos 5 can be added with materials according to actual conditions. Since other silos 5 are not in the working area, they do not affect the work of the picking mechanism 2, thus avoiding the staff from operating close to the working area, having high safety, and at the same time meeting the needs of large-scale material feeding.

The material taking mechanism 2 places the sucked tool handle blank in the clamping position of the positioning mechanism 3. After the tool handle blank abuts the clamping position, it is fixed by the positioning mechanism 3, waiting for the next blank punching process to take the tool handle blank away. When the next blank punching process takes the tool handle away, the material taking mechanism 2 continues to suck the tool handle blank from the corresponding material bin 5 in the stacking mechanism 1 to achieve automatic material taking and positioning. The positioning mechanism 3 cooperates with the material taking mechanism 2 to achieve automatic positioning of the tool handle blank, which can improve the operation safety during the machining process and reduce manual operation errors.

The positioning mechanism 3 fixes the tool handle blank so that the position and angle of the tool handle can adapt to the mold in the next blank punching process, reducing the occurrence of defects caused by inaccurate position between the blank and the mold.

Specifically, the silo 5 includes a base and a limiting rod 7. The base is mounted on the rotating base 4. The limiting rod 7 is detachably connected to the base and forms a receiving cavity for storing tool handle blanks.

More specifically, the base has a plurality of fixed blocks 6, and each of the fixed blocks 6 encloses a position for storing tool handle blanks; an internal threaded hole is provided on the fixed block 6, and one end of the limiting rod 7 is provided with an external thread that cooperates with the internal threaded hole; the limiting rod 7 is threadedly connected to the fixed block 6 to form a accommodating cavity for storing tool handle blanks.

Referring to Fig. 1 and Fig. 2, a rotating base 4 and a plurality of silos 5 are provided in the stacking mechanism 1 to realize non-stop operation and improve the production efficiency of machining. When manually clamping the tool handle blank, the storage cavity of the silo 5 is used to realize the preliminary positioning of the tool handle blank, which can reduce the positioning time after the blank abuts the clamping position. A plurality of fixed blocks 6 are fixedly mounted on the rotating base 4 and the limiting rod 7 can be connected to the fixed block 6 by a threaded connection, so that the silo 5 not only has a high spatial stability, but also reduces the movement of the tool handle caused by machine vibration, and avoids undesirable phenomena such as tool jamming. At the same time, the side of the silo 5 is open, which is convenient for operators to stack or sort the tool handle blanks, and the operator can also quickly know the remaining material by observing the side of the silo 5. The fixed block 6 and the limiting rod 7 are threadedly connected, and different lengths of limiting rods 7 can be used for combined connection, so that the number of tool handle blanks stored in a single silo 5 can be adjusted according to actual work needs.

Specifically, the positioning mechanism 3 includes a base 8 and a plurality of support blocks 9; each of the support blocks 9 is fixed on the base 8, and the clamping position is formed between each of the support blocks 9; a clamping device 11 is provided on one side of the clamping position, and the clamping device 11 is connected to a first cylinder 12, and the first cylinder 12 controls the clamping device 11 to approach or move away from the clamping position.

Specifically, the positioning mechanism 3 further includes a limit block 10, which is arranged on the other side of the clamping position. The limit block 10 is connected to a second cylinder 13, and the second cylinder 13 controls the limit block 10 to approach or move away from the clamping position.

Referring to Fig. 3, when the material taking mechanism 2 sucks the tool handle blank to abut against the clamping position, the first cylinder 12 drives the clamping device 11 to move toward the clamping position. The support block 9, as one end of the fixed tool handle, can limit the movement of the tool handle blank. The clamping device 11 pushes the tool handle blank to the support block 9, and the support block 9 and the clamping device 11 clamp the tool handle together to achieve left and right fixation.

In this embodiment, by setting a limit block 10 in the positioning mechanism, on the one hand, it is used to fix the end of the tool handle blank to prevent the tool handle blank from slipping in the clamping position; on the other hand, the second cylinder 13 is used to drive the limit block 10 close to the clamping position and apply force to the tool handle, so that the upper end of the tool handle blank moves upward and presses on the support block 9, so as to achieve the upper and lower fixation of the tool handle in the clamping position. The support block 9 in the positioning mechanism 3 can clamp the tool blank alone with the limit block 10 or the clamping device 11 therein, or the limit block 10, the support block 9 and the clamping device 11 can clamp the tool handle blank together. When the positioning is completed, wait for the next process to remove the tool handle blank, the clamping device 11 and the limit block 10 can release the tool handle blank for reset, and wait for the next positioning operation.

Specifically, the material picking mechanism 2 includes a fixed plate 14, one end of which is fixed on the machine platform; a cylinder plate 15 is horizontally arranged on the upper part of the fixed plate 14, a pen-shaped cylinder 16 is arranged at one end of the cylinder plate 15, and a guide rail 22 is horizontally arranged on the cylinder plate 15; a third cylinder 17 is installed on the guide rail 22; the piston rod of the pen-shaped cylinder 16 is connected to the third cylinder 17 to control the horizontal movement of the third cylinder 17 along the guide rail 22; one end of the piston rod of the third cylinder 17 is connected to a material picking device 19, the third cylinder 17 controls the material picking device 19 to move up and down in the vertical direction, and the third cylinder 17 controls the material picking device 19 to absorb the tool handle blank in the material bin.

More specifically, the material taking mechanism 2 further includes two buffers 18 ; the two buffers 18 are respectively arranged at the two ends of the cylinder plate 15 , and a position for limiting the horizontal movement of the third cylinder 17 along the pen-shaped cylinder 16 is formed between the buffers 18 .

More specifically, the material picking device 19 includes a material picking plate 20 and a suction cup 21; one side of the material picking plate 20 is connected to the piston rod of the third cylinder 17, and the suction cup 21 is arranged on the other side of the material picking plate 20 away from the third cylinder 17, and the suction cup 21 is connected to the third cylinder 17 through an air pipe, and the third cylinder 17 drives the material picking plate 20 to move up and down in the vertical direction, and the third cylinder 17 controls the suction cup 21 to suck the tool handle blank of the material bin 5.

Referring to Fig. 4, the pen-shaped cylinder 16 drives the third cylinder 17 to move horizontally along the guide rail 22 to the top of the stacking mechanism 1. When it reaches the top of the silo 5, the piston rod of the third cylinder 17 moves up and down in the vertical direction, thereby driving the material taking device 19 connected to the piston rod to move up and down together. When the material taking device 19 abuts against the tool handle blank in the silo 5, the third cylinder 17 controls the material taking device 19 to absorb the tool handle blank in the silo 5, and then the pen-shaped cylinder 16 drives the third cylinder 17 to move horizontally along the guide rail 22 to the top of the positioning mechanism 3, and then the piston rod of the third cylinder 17 moves up and down in the vertical direction, thereby driving the material taking device 19 connected to the piston rod to move up and down together. When the material taking device 19 abuts against the clamping position, the third cylinder 17 controls the material taking device 19 to place the tool handle blank in the clamping position. Wait for the next blanking process to take away the positioned tool handle blank. When the next process takes away the positioned tool handle, the material taking mechanism 2 continues to move above the intermediate material bin 5 to continue the work of sucking and placing.

In order to facilitate the suction and placement of the material picking device 19, a suction cup 21 is provided on the material picking plate 20, and the suction cup is connected to the third cylinder so that the suction cup 21 can quickly suck the surface of the tool handle by negative pressure, and then position the tool handle in the positioning mechanism 3 by pressure relief.

In order to facilitate the control of the movement accuracy of the third cylinder 17 and to make it reciprocate more efficiently in the material picking mechanism 2 and the positioning mechanism 3, buffers 18 are set at both ends of the cylinder plate 15. The third cylinder 17 is located between the buffers 18. When the third cylinder 17 moves horizontally along the guide rail, its moving position is limited by the buffers 18.

Specifically, the tool handle feeding mechanism is further provided with a photoelectric sensor 23 , which is installed on both sides of the machine platform. The photoelectric sensor 23 is used to detect the material status of the silo 5 .

Specifically, the tool handle feeding mechanism further includes a control system, which is connected to the stacking mechanism 1 and is used to control the rotation of the rotating base 4 .

In order to more conveniently set the automatic feeding of the rotation of the stacking mechanism 1, photoelectric sensors 23 are respectively set on both sides of the machine table to monitor the material conditions in the silo 5 corresponding to the working area of the material picking mechanism 2 and the clamping position of the positioning mechanism 3. When the photoelectric sensor 23 senses that the material in the silo 5 is used up, it can drive the system to rotate the stacking mechanism 1, so that the other silo 5 is transferred to the working area of the material picking mechanism 2 to continue the feeding and positioning work.

The working process of this embodiment is briefly described below:

According to the production task, the operator puts the tool handle blank into each bin 5. After the equipment is started, the stacking mechanism 1 rotates the rotating base 4 under the drive of the system, and rotates the position of one of the bins 5 to the working area. The pen-shaped cylinder 16 in the material-retrieving mechanism 3 drives the third cylinder 17 to move horizontally along the guide rail 22 to the top of the stacking mechanism 1. When it reaches the top of the bin 5, the piston rod of the third cylinder 17 moves up and down in the vertical direction, thereby driving the material-retrieving device 19 connected to the piston rod to move up and down together. When the material taking device 19 abuts against the tool handle blank in the silo 5, the third cylinder 17 controls the material taking device 19 to absorb the tool handle blank in the silo 5, and then the pen-shaped cylinder 16 drives the third cylinder 17 to move horizontally along the guide rail 22 to the top of the positioning mechanism 3, and then the piston rod of the third cylinder 17 moves up and down in the vertical direction, thereby driving the material taking device 19 connected to the piston rod to move up and down together. When the material taking device 19 abuts against the clamping position, the third cylinder 17 controls the material taking device 19 to place the tool handle blank in the clamping position. When the tool handle abuts against the clamping position, the limit block 10 and the clamping device 11 in the positioning mechanism 3 move toward the clamping position, and after contacting the tool handle, clamp it in the clamping position, so that the position and direction of the tool handle are fixed. After the tool handle blank is fixed, it is sent to the next process. The photoelectric sensor 23 detects through a pre-set detection point. When the photoelectric sensor 23 senses that the material in the silo 5 is used up, it can drive the system to rotate the stacking mechanism 1, so that the other silo 5 is transferred to the working area of the material taking mechanism 2 to continue the feeding and positioning work, thereby realizing non-stop operation.

Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
