[0002] Sports shoes are important products in modern people's lives. In modern life, people like to wear sports shoes whether going out or exercising. When producing sports shoes, shoe lasts are needed as molds. Shoe lasts are the molding molds of shoes. Shoe lasts can not only determine the shape and style of shoes, but also determine whether the shoes fit well and whether they can protect the feet. Shoe lasts are mostly made of wood, plastic or metal. When the shoes are produced and formed, the shoe lasts inside the shoes need to be taken out;

[0003] Such as "CN110973765B", a detaching machine, in particular, relates to a shoe last detaching machine. The technical problem to be solved is how to design a shoe last detaching machine for sports shoe production that can detach multiple shoe lasts at a time and does not require manual fixing of the shoe lasts. A shoe last detaching machine for sports shoe production, including a base plate, a scissor-type lifting frame, a blanking plate, a mounting frame, a first push frame, a clamping assembly, etc.; a scissor-type lifting frame is installed on the top of the base plate, the top of the scissor-type lifting frame is connected to the mounting frame, the blanking plate is connected to one side of the bottom of the mounting frame, the first push frame is slidably connected in the mounting frame, and a clamping assembly is provided at the end of the first push frame. The present invention drives the clamping assembly to clamp the sports shoes through the transmission assembly, and only the cylinder needs to be manually adjusted during clamping, and no manual operation is required to clamp the sports shoes;

[0004] However, in the prior art, when separating the shoe lasts of sports shoes, a hydraulic shoe last separator is usually used, which requires staff to place the sports shoes with shoe lasts on an inverted shoe last positioning frame to fix the shoe last, and manually press the sports shoe body to start the equipment, and first separate the heel of the sports shoe from the shoe last through the push plate on the equipment. Then the staff pulls the shoe last out of the equipment, manually separates the shoe last from the shoe and places them separately. This process requires many manual operation steps by the staff, which will greatly increase the labor of the staff. As shown in the above-mentioned patent, although it is possible to automatically separate the shoes from the shoe last and place the separated shoes separately from the shoe last, manual loading is still required for staff. The staff needs to place the shoes with shoe lasts one by one at the designated position on the equipment.

[0039] like Figure 1 - Fig.12 As shown, the mounting seat 813 is assembled and connected with the support plate 411 through the telescopic shaft 101, and a third spring 102 is provided between the mounting seat 813 outside the telescopic shaft 101 and the support plate 411. The third spring 102 is a strong spring. Under the action of gravity and the push of the disengagement mechanism, it is difficult to achieve a large-scale separation of the mounting seat 813 and the support plate 411. Only when the first cylinder 913 is driven to drive the push plate 911 toward the mounting seat 813, the third spring 102 can be pushed and unfolded to achieve the effect of moving the push plate 911 toward the mounting seat 813.

[0040] like Figure 1 - Fig.12 As shown, the driving mechanism includes a sprocket 111, a chain 112 and a first motor 113. Three sprockets 111 are provided and are rotatably arranged at a triangular position of the tripod 1. The chain 112 is meshingly sleeved on the outer walls of the three sprockets 111. The chain 112 is assembled and connected to the support plate 411. One sprocket 111 is driven to rotate by the first motor 113. By driving the first motor 113, the sprocket 111 is driven to rotate, and then the chain 112 and all the support plates 411 are driven to rotate, thereby realizing the synchronous rotation and flipping of the shoe lasts arranged on the support plates 411.

[0041] like Figure 1 - Fig.12 As shown, a base 12 is provided below the loading conveyor belt 2, and the lower parts of both ends of the unloading conveyor belt 3 and the bottom of the tripod 1 are respectively assembled and connected to the base 12 through legs, and the provided base 12 is used to support the overall structure above.

[0042] like Figure 1 - Fig.12As shown, the disengagement mechanism includes a fixing frame 131, a connecting shaft 132 and a last pulling wheel 133. The fixing frame 131 is assembled and connected to the top of the two tripods 1 at the lower ends of the two ends. A sleeve shaft 134 is rotatably provided on the fixing frame 131. One end of the connecting shaft 132 is assembled and connected to the sleeve shaft 134 and the other end is assembled and connected to the last pulling wheel 133. The last pulling wheel 133 is located just above the shoe last body 5. The lower ends of the connecting shaft 132 located at the two end surfaces are assembled and connected to the fixing frame 131 through a fourth spring 135. In the initial state, the connecting shaft 132 is pulled by the fourth spring 135 and the weight The fourth spring 135 is used to pull the last wheel 133 from the shoe last body 5. ...

[0043] like Figure 1 - Fig.12 As shown, the pressing and separating mechanism includes a pressing plate 141 and a guide plate 142. The guide plate 142 is inclined and its lower end is assembled and connected to the upper part of the pressing plate 141. Both ends of the pressing plate 141 are assembled and connected to the tripod 1. When the shoe last body 5 moves to the vertical side of the tripod 1 along with the support frame 912, it first passes through the inclined guide plate 142, and the shoe last body 5 and the mounting seat 813 completely enter between the support frame 912 and the guide plate 142. When the support frame 912 moves downward and is located at the pressing plate 141, the shoe last body 5 is completely pushed toward the vertical side of the tripod 1. The positioning shaft 412 is squeezed, and the insert block 614 moves to between the conical block 617 and the positioning shaft 412. When the pressure plate 141 is separated from the shoe last body 5, the insert block 614 and the conical block 617 slide, and under the pushing action of the first spring 613 at one end of the insert block 614, the conical block 617 is driven to move toward the hemispherical block 616 until the insert block 614 moves from the conical block 617 to the hemispherical block 616 and separates from the hemispherical block 616. At this time, the positioning shaft 412 is separated from the shoe last body 5.

[0044] like Figure 1 - Fig.12As shown, a side frame 151 is provided on the tripod 1 below the pressure plate 141, and a separation wheel 152 is rotatably provided between the two side frames 151. A plurality of arc plates 154 are spaced apart on the separation wheel 152. The separation wheel 152 is driven to rotate by a second motor 153. The separation wheel 152 is driven to rotate by the second motor 153, and the arc plates 154 on the separation wheel 152 rotate accordingly. When the shoe last body 5 is separated from the positioning shaft 412 but not completely separated, the separation wheel 152 pushes the shoe last body 5 during rotation to completely separate the shoe last body 5 from the positioning shaft 412.

[0045] like Figure 1 - Fig.12 As shown, an inner frame 161 is provided between the two tripods 1, and the inner frames 161 are provided with multiple and evenly distributed ones. A slide groove 162 is provided on the inner side of the tripod 1, and a through groove 163 is provided on the inner frame 161 to be slidably arranged with the support plate 411. The support plate 411 slides through the multiple inner frames 161, and the two ends of the support plate 411 are slidably connected with the slide groove 162 through rollers 164. The stability of the support plate 411 supporting the shoe last body 5 is guaranteed by the inner frame 161, wherein two rollers 164 are provided, and the two rollers 164 are rotatably arranged in the slide groove 162 separately, which can ensure that the support plate 411 can also slide smoothly through the curved slide groove 162.

[0046] Working principle: The sports shoes with the shoe last body 5 are stably placed on the feeding conveyor belt 2, and the sports shoes are conveyed to the bottom of the tripod 1 by the feeding conveyor belt 2. When the support plate 411 passes the position just above the shoe last body 5, the pushing mechanism is driven to drive the positioning shaft 412 to move downward, and the positioning shaft 412 is just inserted into the slot 611. In the initial state, the second spring 618 in the contracted state drives the conical block 617 to slide and approach the positioning shaft 412, and a gap is left between the conical block 617 and the hemispherical block 616. When the hemispherical block 616 enters the slot 611, the long inclined surface 6142 slides with the arc surface of the outer wall of the hemispherical block 616 until it slides to the conical block 61 7 and the hemispherical block 616. At this time, under the pushing action of the first spring 613, the plug block 614 completely enters the gap between the conical block 617 and the hemispherical block 616, realizing the limiting operation of the plug block 614 on the positioning shaft 412, ensuring the stability of the shoe last body 5 on the support plate 411. Under the driving action of the driving mechanism, the support plate 411 moves along the edge of the tripod 1. When the support plate 411 moves to the inclined surface above the tripod 1, the shoe last body 5 is set upward. At this time, by driving the detachment mechanism, the sports shoes set on the shoe last body 5 can be detached, and the detached sports shoes fall onto the unloading conveyor belt 3 below for transportation, and the shoe last body 5 continues to move under the driving action of the driving mechanism. When the shoe last body 5 moves to the right-angled side position of the tripod 1, a shoe last collection frame can be placed below the right-angled side of the tripod 1. By driving the pressing and separating mechanism, the shoe last body 5 is pressed relative to the positioning shaft 412. At this time, the plug block 614 moves toward the conical block 617. During the movement, the long inclined surface 6142 slides with the outer wall of the conical block 617, and the first spring 613 contracts accordingly until the plug block 614 moves to the bottom of the conical block 617, and the second spring 618 is stretched so that the conical block 617 fits with the bottom of the hemispherical block 616. At this time, the bottom of the conical block 617 is inclined, and the plug block The short inclined surface 6141 of 614 is slidably connected to the conical block 617. At this time, no locking limit can be formed between the inclined surface of the conical block 617 and the plug block 614. At this time, the plug block 614 gradually separates from the conical block 617 under the sliding action until it separates from the hemispherical block 616. At this time, the positioning shaft 412 and the slot 611 cannot be limited, so that the shoe last body 5 and the positioning shaft 412 separate, and the shoe last body 5 falls into the shoe last collection frame. The empty positioning shaft 412 rotates to the bottom of the tripod 1 again to realize the loading operation. There is no need for the staff to manually load and unload and separate the shoe last body 5 during the whole process, which brings great convenience to the staff's work.
