[0033] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0034] like Figure 1 and Figure 2 As shown, the present embodiment is a flexible variable-distance unloading device, comprising a horizontal jig 11 arranged on a turntable 1, in which a plurality of products 10 are orderly supported; a rotary conveyor line 3 is arranged on the outer side of the turntable 1, on which a plurality of rotary seats 31 are rotary-conveyed, and a single rotary seat 31 supports a single product 10; and the present embodiment also comprises a grasping and transferring mechanism 2, on which a plurality of clamping assemblies 8 are installed via a variable-distance assembly 7, and the number of the clamping assemblies 8 is consistent with the number of products 10 in the horizontal jig 11.

[0035] In actual use, the product 10 in the horizontal fixture 11 of the turntable 1 is clamped by the clamping assembly 8 on the grabbing and transferring mechanism 2, and the distance between adjacent clamping assemblies 8 is changed by the variable distance assembly 7. Then, the product 10 is placed on the rotating seat 31 of the rotary conveyor line 3 by the grabbing and transferring mechanism 2, so as to adjust the time distance of the product 10 when it is transferred from the horizontal fixture 11 to the rotary conveyor line 3.

[0036] In this embodiment, through the setting of the rotary conveyor line 3, the rotary seat 31 that supports the single product 10 is rotatably conveyed by the rotary conveyor line 3, and combined with the setting of the variable distance component 7 in the grasping and transferring mechanism 2, it plays a role in the transfer adjustment of the spacing and quantity of the products 10, and can achieve rapid adjustment of the spacing of the products 10 during the transfer process. It is particularly suitable for the situation where the number of products 10 in a single horizontal row of fixtures 11 on the turntable 1 is inconsistent with the number of products 10 on the tray during unloading, and is also suitable for the replacement of products 10 of different models.

[0037] The variable distance component 7 adjusts the spacing distance between adjacent clamping components 8; the center distance between adjacent clamping components 8 is consistent with the center distance between adjacent products 10 in the horizontal row of fixtures 11, or the center distance between adjacent clamping components 8 is consistent with the center distance between adjacent rotating seats 31 on the rotary conveyor line 3, thereby being able to quickly adjust the spacing between adjacent products 10 during the process of transferring the products 10 via the grabbing and transferring mechanism 2.

[0038] The arrangement direction of the plurality of clamping assemblies 8 is consistent with the conveying direction of the rotary conveyor line 3 and the arrangement direction of the horizontally arranged fixtures 11 on the turntable 1 ; thus, the product 10 can be directly transferred via the linear movement of the grabbing and transferring mechanism 2 .

[0039] In actual use, the arrangement directions may be inconsistent, such as being perpendicular to each other. In this case, during the process of clamping or transferring the product 10 by the grasping and transferring mechanism 2 through the clamping assembly 8, horizontal rotation is also required, which can also be used in combination with variable pitch.

[0040] like Figure 3, Figure 4 and Figure 5 As shown in Figure 4 and Figure 5 , the structure of the pitch-changing component 7 is as follows: It includes a plurality of supports horizontally arranged side by side on the side of the lifting seat 23 in the grasping and transferring mechanism 2. One support at the end is fixed to the lifting seat 23 to form a fixed seat 72, and the remaining supports are slidably installed on the lifting seat 23 via a horizontally arranged transverse track 71 to form a moving seat 73. An adapter joint 74 is installed between adjacent supports; one end of the adapter joint 74 is fixedly installed on the support, a transverse chute 741 is opened at the other end of the adapter joint 74, and a pin shaft 75 is installed through the chute 741 and facing another support; it also includes a linear drive member 77 for pulling the moving seat 73 to move along the transverse track 71.

[0041] In actual use, with the operation of the linear drive member 77, the moving seat 73 is pulled to move towards or away from the fixed seat 72, thereby realizing the adjustment of the pitch, so as to smoothly transfer from the horizontally arranged fixtures 11 with a smaller pitch on the turntable 1 to each rotary seat 31 with a larger pitch on the rotary conveyor line 3.

[0042] During the horizontal relative movement of adjacent moving seats 73, the pin shaft 75 moves relative to the corresponding chute 741, playing a guiding role.

[0043] A transverse long groove 231 is opened through the lifting seat 23. A push-pull plate 76 is installed on the moving seat 73 far from the fixed seat 72 and passes through the long groove 231 backward. The push-pull plate 76 is installed at the output end of the linear drive member 77.

[0044] In this embodiment, the linear drive member 77 can be a standard product such as an existing air cylinder or oil cylinder that can output linear power.

[0045] Two transverse tracks 71 are arranged at intervals up and down, and the long groove 231 is opened between the two transverse tracks 71.

[0046] A protrusion 743 extends laterally from the middle of one end of the adapter joint 74, and a groove 742 is recessed in the middle of the other end of the adapter joint 74 opposite to it. The protrusion 743 and the groove 742 of adjacent adapter joints 74 are horizontally adapted.

[0047] In this embodiment, protrusions 743 and grooves 742 are respectively arranged at both ends of the adapter joint 74 in the horizontal direction, and the protrusions 743 and grooves 742 of adjacent adapter joints 74 are horizontally adapted. Thus, during the pitch adjustment process, the cooperation between the protrusions 743 and the grooves 742 can play a guiding role when adjacent adapter joints 74 move relative to each other, and the overall structure is compact, ingenious, and reasonable.

[0048] In this embodiment, the adapter joints 74 are interchangeable.

[0049] Such as Figure 6As shown in the figure, the rotary conveyor line 3 includes two sets of conveyor lines arranged in parallel. On both sides of the end of the rotary conveyor line 3, a limiting mechanism 6 and a pushing mechanism 5 are respectively arranged. The pushing mechanism 5 pushes a plurality of rotary seats 31 arranged on one set of conveyor lines to the other set of conveyor lines.

[0050] It further includes a stop mechanism 4. The stop mechanism 4 includes a stop member that moves along the width direction of the rotary conveyor line 3, and a preset number of rotary seats 31 are stopped by the stop member.

[0051] In actual use, the rotary seat 31 moves along with the conveyor line of the rotary conveyor line 3. Through the action of the stop mechanism 4, a preset number of rotary seats 31 in the conveying direction can be stopped. Then, the pushing mechanism 5 combines with the limiting mechanism 6 to push and switch the preset number of stopped rotary seats 31 to the other conveyor line, realizing the rotation of the rotary seat 31 between the two sets of conveyor lines. At the same time, it is also convenient for the grasping and transferring mechanism 2 to place the product 10 on the rotary conveyor line 3.

[0052] In this embodiment, the pushing mechanism 5, the limiting mechanism 6, and the stop mechanism 4 can respectively be composed of plate members driven by linear driving power to move in a preset direction; the linear driving power can be standard products such as existing cylinders and oil cylinders that can output linear power.

[0053] A single set of clamping components 8 is a pair of clamping jaws equipped with a clamping finger cylinder, and a single product 10 is clamped by the pair of clamping jaws.

[0054] The structure of the grasping and transferring mechanism 2 is: it includes a linear moving module 21 spanning across the rotary conveyor line 3. A horizontal moving seat is installed on the linear moving module 21. A lifting seat 23 is installed on the side of the horizontal moving seat through a lifting component 22, and a clamping component 8 is installed on the side of the lifting seat 23.

[0055] In actual use, according to actual production requirements, for example, another grasping and transferring mechanism 2 and a pitch-changing component 7 can be equipped after the rotary conveyor line 3 to place the products 10 on the rotary conveyor line 3 in a preset quantity and even at a preset pitch on a tray.

[0056] Of course, in actual use, the product 10 can also be conveyed to the next process one by one through the rotary conveyor line 3 for further assembly and other production processes.

[0057] The utility model can realize the blanking of products in a preset quantity and at a preset pitch, effectively helping to realize the automation of blanking and tray loading, and having good use flexibility.
