Description

Technical Field

[0001] The utility model relates to the technical field of roll changing in carpet fabric production, in particular to a carpet fabric roll changing device. Background Art

[0002] In the carpet production process, it is inevitable to transport and transfer the processing rollers loaded with carpet fabrics to be processed to other processing equipment. During the entire processing process, the carpet fabric and the processing rollers are combined into a rolled intermediate piece. Conventional processes do not allow the carpet fabric to be unloaded to avoid wasting too much manpower and material resources. The only way is to change the rolls and process them again. In the prior art, the carpet fabric roll changing process is often replaced by an electric hoist or a crane. Specifically, the processing rollers placed on a wooden pallet (the parts not covered by materials on both sides) are fixed with a lifting rope, lifted by a crane, and then moved horizontally to the installation location of the relevant equipment. During this period, workers are required to hold the rollers by hand. During the transfer process, the intermediate piece may fall due to the loose lifting rope, thereby injuring the workers, which is extremely unsafe. In addition, winding and loading and unloading related auxiliary parts such as the lifting rope are quite troublesome and extremely time-consuming.

[0003] Therefore, in the process of carpet fabric processing, there is an urgent need for a device that can assist manual roll changing, which can improve safety and roll changing efficiency. Utility Model Content

[0004] In order to make up for the deficiencies in the prior art and achieve the above functions, the utility model provides a carpet fabric roll changing device.

[0005] The utility model is realized through the following technical solutions:

[0008] The transverse movement mechanism includes four single-axis drivers, which are equidistant from front to back and from left to right. The rotating axes on the single-axis drivers are relatively set up left to right, and the sliders on each single-axis driver are connected to each rotating motor through the same fixing plate.

[0009] Furthermore, a square groove is provided in the middle of the rear end of the straight plate, and the protruding parts on both sides of the square groove are completely chamfered to form anti-collision angles, and the protruding parts are respectively provided with through holes of equal size at the front and rear; the rotating block is "L"-shaped, and fixed threaded holes and rotating through holes corresponding to the through holes at the rear end of the straight plate are respectively set at the front and rear below the rotating block, and the rotating block is fixed in the square groove by hexagonal bolts and pull rings, and a handle is installed above the rotating block.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the utility model.

[0026] like Figure 2 As shown, the utility model comprises three major components: a circulation mechanism, a tilting and rotating mechanism and a transverse movement mechanism.

[0027] like Figures 2 to 7 As shown, the flow mechanism includes a pair of left and right parallel flow racks 1, which can support the left and right ends of the processing roller 801. The flow rack 1 includes a long straight plate 101, and arc-shaped buffer pads 102 with equal intervals are fixed above the straight plate 101 to prevent the processing roller 801 from moving too fast on the flow rack 1. The front and rear ends of the flow rack 1 are respectively installed with a hook plate 2 and a rotating block 3.

[0028] The hook plate 2 is a vertical block perpendicular to the straight plate 101, and its purpose is to hook the carpet fabric on the wooden pallet 9 at the beginning. A concave stop block 201 is installed on the side of the hook plate 2 facing the straight plate 101, which can adapt to the cylindrical processing roller 801. The straight plate 101 and the stop block 201 are elastically connected by a spring 202 to play a buffering role and prevent the material roll 8 from being broken. A circular through hole is set in the center of the stop block 201, and a photoelectric sensor 203 is installed in the hook plate 2 corresponding to the through hole to detect the position of the material roll 8 on the flow rack 1.

[0029] A square groove is provided in the middle of the rear end of the straight plate 101, and the protruding parts on both sides of the square groove are completely chamfered to form anti-collision angles 103 to prevent the interference with the processing roller 801 when unloading the material roll 8, and the front and rear of the protruding parts are respectively provided with through holes of equal size; the rotating block 3 is "L"-shaped, and the front and rear of the rotating block 3 are respectively provided with fixed threaded holes 304 and rotating through holes 302 corresponding to the through holes at the rear end of the straight plate 101. The rotating block 3 is fixed in the square groove by a hexagonal bolt 303 and a pull ring 301. When the material roll 8 is unloaded to the corresponding equipment, the hexagonal bolt 303 can be properly unscrewed, and the material roll 8 can be guided to the correct position by rotating the rotating block 3. A handle 305 is installed above the rotating block 3 to assist the rotation.

[0030] The tilting and rotating mechanism includes two rotating joints 402 installed on each flow rack 1. The rotating joints 402 are installed on the outside of the two flow racks 1 and are rotated and fixed by pins. The rotating joints 402 are connected to the supporting mechanism 4 through the supporting rod 401. The supporting mechanism 4 is connected to the shaft of the rotating motor 5 through the fixed shaft at the bottom. The two can be connected by conventional couplings or the like, which will not be repeated here.

[0031] The support mechanism 4 is equipped with a driving motor capable of driving the support rod 401 to extend and retract. The left and right lateral driving motors and the rotating motor 5 all operate synchronously, that is, the left and right driving motors operate synchronously to ensure that the left and right support rods extend and shorten synchronously, and the left and right rotating motors 5 operate synchronously to ensure that the inclination angles are consistent, thereby preventing the material roll 8 on the flow rack 1 from tipping over axially.

[0032] The transverse movement mechanism includes four single-axis drives 6, the purpose of which is to adapt to processing rollers 801 of different lengths on pallets at different positions. The single-axis drives 6 are equidistant front, back, left, and right. The rotating axes on the single-axis drives 6 are relatively set left and right. The sliders on each single-axis drive 6 are connected to each rotating motor 5 through the same fixed plate. A displacement sensor 601 is installed on the side of each single-axis drive 6 to monitor and infer the current distance of the flow rack 1; the single-axis drives 6 in the front and back directions are fixed on the same base plate 7 and run synchronously to ensure that the front and rear sliders are in the same left and right positions, and two parallel base plates 7 are set on the left and right to fix the single-axis drives 6.

[0033] All the above electrical components are connected to a conventional PLC controller and controlled by its internal coding.

[0034] The working principle of the utility model is as follows: (1) a forklift places a wooden pallet 9 with a material roll 8 in front of the device, and at this time, the rotating motor 5 and the driving motor inside the supporting mechanism work together to pass through the processing rollers 801 on both sides of the material roll 8 and place the material roll 8 on the front end of the flow rack 1 (see Figure 5 ). (2) Then the rotating motor 5 and the driving motor inside the supporting mechanism work together again to lift the material roll 8 to the corresponding position of the rear equipment (see Figure 2 ), during which the two front support rods 401 can be extended and the two rear support rods 401 can be shortened to form a height difference. The material roll 8 is decelerated by the buffer pad 102 and slowly moves to the rear of the flow rack 1 and is blocked by the rotating block 3. (3) Remove the hexagonal bolt 303 and use the handle 305 to rotate the rotating block 3 (see Figure 6 ), if the rotating block 3 cannot be rotated, the pull ring 301 can be rotated to assist the rotation, and finally the material roll is placed on the relevant parts of the rear equipment where the processing roller 801 is placed. (4) The process of unloading the carpet fabric can be reversed by steps (1) to (3) to achieve the purpose of changing the roll.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
