Description

TECHNICAL FIELD

[0001] The utility model relates to shoe stretcher preparation device technical field, especially in a kind of shoe stretcher stacking bin. BACKGROUND

[0002] Shoe stretcher is as the key tool of shoemaking and footwear storage, after preparation, it needs to be transferred to next station by automatic equipment.In the existing production process, shoe stretcher is put into transfer table from top to bottom after being sucked out of mould by suction nozzle, and then it is transferred to conveying belt by push-pull mechanism.However, since shoe stretcher is in front-leaning state after forming, and the bottom 10 is vertically arranged at the back side, the bottoms 10 of adjacent shoe stretchers interfere with each other when suction nozzle is put into transfer table, so they cannot be stacked directly, but can only be placed in single layer, which results in extremely low utilization rate of storage space of transfer table. SUMMARY

[0003] The utility model discloses a kind of shoe stretcher stacking bin, to overcome the defects of prior art, solve the technical problem that shoe stretcher cannot be stacked due to front-leaning state and back side bottom when suction nozzle is put into shoe stretcher.

[0004] The utility model discloses a kind of shoe stretcher stacking bin, including mounting frame, the mounting frame is internally provided with the stacking bin body for receiving shoe stretcher put by suction nozzle, the top of the stacking bin body is equipped with the open structure compatible with suction nozzle put path, characterized by: at least one support rod for supporting the front end of shoe stretcher is further provided in the stacking bin body.

[0005] When shoe stretcher is in front-leaning state after forming, and the bottom 10 is vertically arranged at the back side, the support rod is supported at the front end bottom area of shoe stretcher, so that shoe stretcher is in back-inverted state, and then the interference between the bottoms of adjacent shoe stretchers is eliminated, so that multiple shoe stretchers are sequentially and orderly stacked along the height direction of stacking bin body.

[0006] The side of the stacking bin body is equipped with discharge port, and the stacking bin body is equipped with support rod driving element for driving support rod extension and contraction; when discharging, the support rod driving element drives support rod to retract, so that the support and block of stacked shoe stretcher are cancelled, so that stacked shoe stretcher can be pushed out or pulled out as a whole from discharge port.

[0007] The above technical scheme has the following beneficial effects:

[0008] By the accurate support of support rod to the front end of shoe stretcher, front-leaning shoe stretcher with bottom is inverted back, so that the stacking interference between the bottoms of adjacent shoe stretchers is directly eliminated, multiple shoe stretchers are sequentially and orderly stacked, compared with traditional flat storage mode, the utilization rate of storage space is improved, and the continuous put rhythm of automatic suction nozzle is perfectly adapted, without manual adjustment of shoe stretcher posture.

[0009] The support rod drive mechanism enables rapid switching between support and avoidance states. Combined with the structural design of the discharge port, the stacked shoe supports can be directly pulled out or pushed out as a whole.

[0010] The overall structure is simple and compact, and the coordinated action of the support rod and the drive component is precise and reliable. When supporting, it can stably maintain the backward posture of the shoe support, and when retracting, it can completely remove the obstruction, ensuring a smooth connection between stacking and unloading processes. It can be directly integrated into automated production lines and is suitable for continuous production needs such as nozzle dispensing and conveyor belt connection, making it highly practical.

[0011] Without modifying the structure of the shoe tree itself, the stacking problem of forward-leaning shoe trees with bottoms can be solved simply by the support and posture adjustment design of the stacking compartment. It is highly adaptable and easy to operate, reducing the cost of equipment modification and production adaptation.

[0012] A further feature of this invention is that the inner rear wall of the stacking compartment body on the frame forms a blocking surface, constituting a blocking structure that limits the sliding movement of the shoe support in the backward-falling state.

[0013] The above technical solution has the following effects:

[0014] The obstruction surface formed by the inner rear wall of the stacking chamber constitutes a reliable sliding limit structure, which can accurately limit and block the shoe support in the backward state, effectively preventing the shoe support from sliding out of the stacking chamber due to backward inertia or stacking pressure. This ensures that the shoe support is stable and orderly arranged during multi-layer stacking, further improving the reliability and safety of stacking, providing structural protection for increasing stacking density, and ensuring that the shoe support after multi-layer stacking always remains in a regular state before discharge, avoiding discharge jamming caused by shoe support deviation.

[0015] A further feature of this invention is that a mounting plate is mounted on the mounting frame, and the support rod drive component is disposed on the mounting plate.

[0016] The mounting plate has inclined sliding grooves, and the support rod drive is adjustablely slidably assembled in the sliding grooves to achieve adjustable fit for shoe supports of different specifications.

[0017] The support rod is inserted laterally into the stacking compartment body, and the stacking compartment body is provided with a clearance hole that matches the inclined trajectory and adjustment stroke of the sliding groove hole, so as to avoid motion interference when the support rod drive component is adjusted.

[0018] The above technical solution has the following effects:

[0019] The mounting plate provides a stable assembly base for the support rod drive component. Combined with the inclined sliding groove hole design, the support rod drive component can slide along the sliding groove hole to adjust the installation position, thereby flexibly changing the position of the support rod and accurately adapting to shoe supports of different sizes and specifications, greatly improving the versatility and adaptability of the equipment.

[0020] The tilt trajectory and adjustment stroke of the avoidance holes and sliding groove holes on the stacking bin body are precisely matched, which can effectively avoid motion interference during the adjustment of the support rod drive component, ensure smooth sliding adjustment of the support rod drive component without jamming, and at the same time ensure the movement stability of the support rod after horizontal insertion, avoid structural collisions or functional failures during the adjustment process, and improve the reliability of equipment operation.

[0021] This adjustable structure design allows for adjustment of support parameters without complex disassembly, making it convenient and efficient to operate. It shortens the equipment debugging time when switching production of different shoe trees, reduces production changeover costs, and further adapts to the continuous operation requirements of automated production lines, demonstrating significant practical value.

[0022] A further feature of this invention is that the stacking compartment body is formed by two spaced-apart side plates and a bottom plate that seals the rear side of the two side plates. Both the side plates and the bottom plate are slidably mounted on the mounting frame to achieve adjustable width of the stacking compartment body.

[0023] It also includes a locking mechanism, which is configured to lock and fix the relative position of the side plate and the bottom plate after the width of the side plate and the bottom plate are slidably adjusted along the mounting bracket.

[0024] The above technical solution has the following effects:

[0025] The stacking compartment is composed of side plates and a bottom plate, both of which are slidably mounted on the mounting frame. The width can be adjusted by sliding the relative position of the side plates and the bottom plate, precisely adapting to shoe supports of different widths. Combined with the previously designed adjustable support rod, it forms a two-way adjustable solution of "width + support parameters", further expanding the equipment's adaptability range. It can meet the stacking needs of multiple shoe supports without replacing the main body of the stacking compartment, greatly improving production flexibility.

[0026] After width adjustment, the locking mechanism can quickly lock the relative position of the side plate and the bottom plate, ensuring the stability of the stacking compartment structure after adjustment. This prevents width deviation caused by shoe support pressure or equipment vibration during stacking, ensures the lateral positioning accuracy of the shoe support when stacking multiple layers, and provides a structural foundation for the stable support of the support rod, thereby improving the overall reliability of the equipment operation.

[0027] The sliding assembly design makes width adjustment convenient and efficient. The quick locking function of the locking mechanism shortens the equipment debugging time when switching between different sizes of shoe trees, reduces production changeover costs, adapts to the continuous operation rhythm of automated production lines, and has a simple structure that is easy to maintain, reducing equipment downtime for maintenance and further improving production efficiency.

[0028] A further feature of this utility model is that both the side plates and the bottom plate are provided with bending portions, and each bending portion is provided with an elongated slot.

[0029] The mounting bracket has positioning holes at the positions of each long slot, and the long slots and positioning holes are matched with the sliding adjustment of the side plate and bottom plate along the mounting bracket.

[0030] The above technical solution has the following beneficial effects:

[0031] The bends on the side plates and bottom plates not only provide a stable platform for opening long slots, but also enhance the structural rigidity of the side plates and bottom plates, preventing deformation under width adjustment or stacking pressure, providing a stable structural foundation for shoe support stacking, and improving the overall durability of the equipment.

[0032] The long slots and positioning holes on the mounting bracket precisely match to form a reliable sliding guide structure, which can limit the sliding direction of the side plates and bottom plates along the mounting bracket, avoid deviation and jamming during adjustment, ensure smooth and accurate width adjustment, and enable the width of the stacking compartment body to strictly adapt to the lateral dimension requirements of different shoe support sizes.

[0033] The length design of the long slot and the matching method of the positioning hole clearly define the adjustment range of the side plate and the bottom plate. This not only meets the adaptation needs of multiple shoe trees, but also avoids structural interference caused by over-adjustment. At the same time, it provides a stable positioning reference for the locking mechanism, making the position of the side plate and bottom plate more accurate after locking, and further ensuring the structural stability after width adjustment.

[0034] This mating structure is simple in design and easy to process. It can achieve smooth adjustment without complex transmission components, which reduces the processing and assembly costs of the equipment. In addition, the mating clearance between the long slot and the positioning hole is easy to control, which can maintain good adjustment accuracy for a long time and reduce the frequency of equipment maintenance.

[0040] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0041] In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] The main frame has: Mounting bracket 1: providing a stable supporting foundation for the entire equipment.

[0043] Side plate 2: Cold-rolled steel sheet bent into shape.

[0044] Base plate 3: Cold-rolled steel plate is bent and formed, and is enclosed with the two side plates 2 through the bending part 4 to form the stacking bin body. One side of the stacking bin body is set with an opening to form a discharge port 5.

[0045] Bending section 4: The edges of the side plate 2 and the bottom plate 3 are both bent outward at 90° to form bending section 4, and each bending section 4 has a long slot 41 along the length direction.

[0046] Mounting plate 6: It is fixed to the mounting bracket 1 by bolts. The mounting plate 6 has an inclined sliding groove hole 61. The preferred inclination angle of the sliding groove hole 61 is 30° (angle with the horizontal direction).

[0047] Support rod 7: Inserted laterally into the corresponding opening in side plate 2;

[0048] Support rod drive component 8: preferably a cylinder, the cylinder body is locked to the mounting plate 6 by a nut, and sliding adjustment can be achieved when the nut is loosened.

[0049] 9. The clearance hole is opened on the side plate 2 of the stacking compartment body. It is preferably an oblong hole. Its inclined trajectory is completely consistent with the sliding groove hole 61 on the mounting plate 6, and its length covers the maximum adjustment stroke of the sliding groove hole 61, so as to avoid movement interference with the side plate when the cylinder is adjusted.

[0050] Positioning hole 11: It is formed on the mounting bracket 1 and corresponds to the long slot hole 41 of the bending part 4. It is used to cooperate with the locking mechanism to fix the position.

[0051] Locking mechanism: Not shown in the figure. The bolt and the anti-loosening nut cooperate. After the bolt passes through the long slot 41 of the bent part 4, it is threaded to the positioning hole 11 of the mounting bracket 1 or the mounting bracket 1 is clamped by the nut. After tightening the nut, the position of the side plate 2 and the bottom plate 3 can be locked.

[0052] Blocking surface 31: It is formed by the front end face of the base plate 3. The end face is polished and fits with the rear contact surface of the shoe support to form a sliding limiting structure, which ensures that the shoe supports stacked in multiple layers can be limited. In particular, the blocking surface 31 has a relief groove in the middle, which allows the lever to be inserted on the front side and pulled backward from the relief groove to pull out the shoe supports stacked on the stacking compartment body.

[0053] The specific installation process is as follows: Align the bent parts 4 of the side plate 2 and the bottom plate 3 with the positioning holes 11 of the mounting bracket 1, and pre-connect the bolts through the long slot holes 41 and the positioning holes 11 (do not tighten them yet), so that the side plate 2 and the bottom plate 3 can slide and adjust along the mounting bracket 1.

[0054] Then, the mounting plate 6 is fixed to the mounting bracket 1 with bolts, ensuring that the mounting plate 6 is flat and without tilt;

[0055] Furthermore, the support rod drive component 8 (cylinder) is assembled onto the sliding groove hole 61 of the mounting plate 6, and the position of the support rod drive component 8 is adjusted manually or electrically.

[0056] The support rod 7 passes laterally through the clearance hole 9 on the side plate of the stacking warehouse body;

[0057] Check that the movement of each component is smooth: push the side plate 2 and the bottom plate 3 to confirm that the width adjustment is not stuck; start the cylinder to verify that the extension and retraction of the support rod 7 is smooth and that there is no interference with the clearance hole 9.

[0058] Stacking process: The suction nozzle sequentially places the formed forward-leaning shoe supports with bottoms into the stacking chamber body; after the shoe supports fall into the stacking chamber body, the front bottom contacts the support rod 7, and under the supporting force of the support rod 7, the shoe supports fall backward; the subsequently placed shoe supports are stacked on top of the previous shoe supports. Since the bottom has already avoided the stacking path as the shoe supports fall backward, there is no obstruction or interference between adjacent shoe supports, and finally a multi-layered orderly stack is formed.

[0059] Discharge process: When the shoe supports in the stacking bin reach the set number of layers, the control system sends a discharge signal, the support rod drive 8 (cylinder) is ventilated, the piston rod retracts, and the support rod 7 moves to the outside of the stacking bin, completely removing the support and obstruction of the shoe supports; at this time, the neatly stacked shoe supports are pushed from the discharge port 5 to the next process through the production line's pushing mechanism (or manually pushed out), and the discharge process is smooth and without jamming;

[0060] After the material is discharged, the cylinder resets, the support rod extends back into the stacking bin body, and the equipment enters the next stacking cycle.
