Description

Technical Field

[0001] The present application relates to the technical field of palletizing equipment, and particularly to a palletizing equipment for square cloth pieces. Background Art

[0002] Palletizing equipment is widely used in industrial production for stacking and handling materials. Especially in the textile industry, it is of great significance to efficiently stack the cloth pieces after cloth cutting. Through the application of palletizing equipment, not only can the production efficiency be improved, manual intervention be reduced, but also the neatness of cloth piece stacking can be ensured, thereby enhancing the overall production process level. With the development of automation technology, the application of palletizing equipment in the textile industry is becoming more and more extensive, and its performance and functions directly affect the stability of the production process and product quality.

[0003] In the prior art, in order to solve the problems of handling and stacking cloth pieces, the operation is usually carried out by using a pick-up head with a fixed pitch in cooperation with negative pressure adsorption. Specifically, after the cloth pieces are transported to the designated position by a conveyor belt, the pick-up head of the palletizing equipment adsorbs the cloth pieces by negative pressure, and transports the cloth pieces to the target position for stacking through a horizontal movement mechanism and a lifting mechanism. In addition, in order to adapt to cloth pieces of different sizes, some equipment also adopts a combination of multiple groups of pick-up heads with fixed pitches to cover a certain size range. However, these means mainly rely on fixed structural designs and lack adaptability to changes in cloth piece sizes.

[0004] However, due to the soft texture of the cloth pieces, unstable phenomena are likely to occur during the picking process, and even the cloth pieces cannot be effectively adsorbed, resulting in wrinkles or collapses of the cloth pieces during handling and stacking, seriously affecting the stacking efficiency and the quality of the cloth pieces. Therefore, how to achieve stable picking of cloth pieces of different sizes has become an urgent technical problem to be solved. Summary of the Invention

[0005] In order to solve the above problems, the present application provides a palletizing equipment for square cloth pieces.

[0006] The palletizing equipment for square cloth pieces provided by the present application adopts the following technical solutions: A palletizing equipment for square cloth pieces includes a horizontal movement mechanism and a lifting mechanism, and further includes a palletizing mechanism. The palletizing mechanism includes a plurality of sliding frames, a sliding groove is formed in the sliding frame, a pick-up head is slidably installed in the sliding groove, the pick-up head includes a housing, a negative pressure pick-up probe is movably arranged in the housing, and a tensioning component for driving the negative pressure pick-up probe to move is further arranged in the housing.

[0007] By adopting the above technical solution, the sliding groove on the sliding frame allows the picking head to adjust its position according to the size of the fabric piece, thus realizing the stable picking of fabric pieces of different sizes and avoiding the unstable picking problem caused by the fixed spacing of the picking head. The negative pressure picking probe can effectively adsorb the fabric piece, while the tensioning component can adjust the position of the negative pressure picking probe according to the specific situation of the fabric piece, making the fabric piece tighten towards the surrounding during the adsorption process, reducing the phenomenon of the middle part of the fabric piece collapsing, thereby improving the picking and stacking efficiency of the fabric piece and reducing the risk of wrinkles and creases caused by the collapse.

[0008] Preferably, a pushing cavity is formed in the housing. The tensioning component includes a driving shaft, and a spiral cam is fixedly arranged on the driving shaft. The spiral cam includes a spiral part and a rotating part. The rotating part is fixed to the driving shaft, and the spiral part is arranged as a toothed piece with a spiral shape. A probe roller is fixedly arranged at the top of the negative pressure picking probe, and the probe roller is in transmission engagement with the spiral cam.

[0009] By adopting the above technical solution, the spiral cam on the driving shaft is in transmission engagement with the probe roller, which can realize the precise movement of the negative pressure picking probe in the housing. The spiral part of the spiral cam is designed in the shape of a toothed piece. Combined with the transmission engagement of the probe roller, it ensures the stable movement and accurate positioning of the negative pressure picking probe, effectively improving the adaptability to fabric pieces of different sizes. The fixed connection between the rotating part and the driving shaft guarantees the reliability of power transmission, further improving the working stability of the picking head. The overall structure is compact, optimizing the utilization of the internal space of the picking head, and providing a guarantee for realizing efficient and stable picking and stacking of fabric pieces.

[0010] Preferably, a limiting part is arranged on the probe roller, and the limiting part is in clamping fit with the spiral part.

[0011] By adopting the above technical solution, a limiting part is arranged on the probe roller and is in clamping fit with the spiral part, which can effectively prevent the probe roller from disengaging during the transmission of the spiral cam, ensuring the stable movement of the negative pressure picking probe. Combined with the overall design of the sliding frame, the picking head and the tensioning component, this structure further improves the adaptability of the picking head to fabric pieces of different sizes, avoiding problems such as fabric piece wrinkles or ineffective picking caused by unstable picking, thereby improving the picking and stacking efficiency of fabric pieces.

[0012] Preferably, an idle wheel is also arranged on the driving shaft, and an anti-disengagement plate is fixedly arranged at one end of the idle wheel.

[0013] By adopting the above technical solution, arranging an idle wheel on the driving shaft and fixedly arranging an anti-disengagement plate at one end of the idle wheel can effectively prevent the negative pressure picking probe from disengaging during the movement. The setting of the idle wheel enables the probe roller to have a position that cannot be driven by the driving shaft, so that the probe roller does not rotate when the driving shaft rotates.

[0014] Preferably, traveling wheels are rotatably provided at both ends of the driving shaft, roller grooves are provided at the top of the sliding frame corresponding to the traveling wheels, and the traveling wheels are installed in the roller grooves.

[0015] By adopting the above technical solution, the setting of the walking wheel enables the driving shaft to roll stably on the sliding frame, thereby driving the negative pressure pickup probe to move along the sliding frame, improving the stability of the movement of the pickup head in the sliding groove. The setting of the roller groove guides and limits the walking wheel, further ensuring the stability of the pickup head during movement, and avoiding the problem of failed cloth pickup or uneven stacking due to unstable movement.

[0016] Preferably, a driving cavity is further provided in the shell, a driving motor is arranged in the driving cavity, and the driving motor is used to drive the driving shaft.

[0017] By adopting the above technical solution, the setting of the drive motor can provide stable power output for the drive shaft, ensure the precise rotation of the drive shaft, and thus drive the spiral cam to rotate. This enables the negative pressure pickup probe to achieve precise position adjustment in the shell, effectively adapt to the picking needs of cloth pieces of different sizes, and improve the picking stability. This solution further optimizes the picking efficiency and stacking quality of the cloth pieces by the palletizing equipment, reduces the wrinkle problem caused by the collapse of the cloth pieces, and improves the overall work efficiency.

[0018] Preferably, a spring chamber is provided in the shell, and the tensioning assembly further comprises a toggle rod, one end of which is rotatably provided with a toggle roller, and the other end of which is fixedly provided with a toggle sleeve, and the negative pressure pickup probe is slidably sleeved on the toggle sleeve.

[0019] By adopting the above technical solution, the toggle roller at one end of the toggle rod can roll in the spring cavity, thereby adjusting the position of the negative pressure pickup probe when subjected to external force, so that the negative pressure pickup probe can be adaptively adjusted according to the specific shape and position of the cloth piece. The toggle sleeve at the other end of the toggle rod is slidably connected with the negative pressure pickup probe, further improving the mobility of the negative pressure pickup probe.

[0020] Preferably, a return spring is sleeved on the toggle rod.

[0021] By adopting the above technical solution, the setting of the reset spring enables the toggle rod to automatically return to its original position after the force disappears, thereby ensuring that the negative pressure picking probe quickly returns to its initial state after completing the cloth picking action, thereby improving the working efficiency and stability of the equipment.

[0022] Preferably, a positioning groove is further formed in the sliding frame, and a positioning block is arranged in the positioning groove. The positioning block includes a sliding portion capable of sliding relative to the positioning groove, and the positioning block further includes a clamping portion. A clamping groove is formed in the clamping portion, and a slope surface connected to the clamping groove is further formed in the clamping portion.

[0023] By adopting the above technical solution, a positioning groove is formed in the sliding frame and the positioning block is arranged. The positioning block includes a sliding portion and a clamping portion. The sliding portion can slide relative to the positioning groove, realizing flexible adjustment of the positioning block, so as to adapt to the picking requirements of cloth pieces of different sizes.

[0024] Preferably, a moving groove for the negative pressure picking probe to move is formed at the bottom of the housing.

[0025] By adopting the above technical solution, the moving groove formed at the bottom of the housing enables the negative pressure picking probe to move smoothly in the housing, so as to adapt to the picking requirements of cloth pieces of different sizes. This design effectively improves the flexibility and adaptability of the picking head, avoids the problem of unstable picking caused by the cloth piece size exceeding the fixed range, and further improves the picking and stacking efficiency of the cloth piece.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The sliding groove on the sliding frame cooperates with the slidably mounted picking head, and can flexibly adjust the distance between the picking heads according to the size of the cloth piece, effectively solving the problem of instability of the fixed-distance picking head when processing cloth pieces of different sizes, and significantly improving the picking and stacking efficiency of the cloth piece; 2. The negative pressure picking probe realizes moving adjustment through the tensioning assembly, and can maintain an appropriate tension when adsorbing the cloth piece, making the cloth piece taut, so as to solve the problem of collapse in the middle of the cloth piece, avoid creases and wrinkles when stacking the cloth pieces, and improve the stacking quality of the cloth piece; 3. The flexible picking head adjustment mechanism combined with the negative pressure adsorption function can adapt to square cloth pieces of various sizes, enhance the versatility and adaptability of the equipment, and reduce the risk of picking failure caused by changes in the cloth piece size.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] In the description of the invention, it should be understood that for the orientation description, such as the orientation or positional relationship indicated by up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0031] The embodiment of the present application discloses a palletizing device for square cloth pieces. Refer to Figure 1 and Figure 2 , which includes a horizontal moving mechanism and a lifting mechanism. Among them, the horizontal moving mechanism and the lifting mechanism are conventional. A palletizing device for square cloth pieces further includes a palletizing mechanism. Among them, the horizontal moving mechanism is used to drive the palletizing mechanism to move horizontally, and the lifting mechanism is used to drive the palletizing mechanism to move up and down. The palletizing mechanism includes a plurality of sliding frames 1, and sliding grooves 11 are formed on the sliding frames 1. In the embodiment of the present application, there are two sliding frames 1 arranged horizontally and vertically, and the sliding frames 1 are staggered in a cross shape. A plurality of sliding frames 1 are fixed by a fixing plate to ensure that the sliding frames 1 can move as a whole. A pick-up head 10 is slidably installed in the sliding groove 11. In the embodiment of the present application, a pick-up head 10 is arranged at each end of a sliding frame 1 to ensure that the two ends of the cloth piece are stressed evenly during grasping. The pick-up head 10 can slide along the sliding groove 11 to facilitate the adjustment of the picking position. The pick-up head 10 includes a housing 21, and a negative pressure pick-up probe 3 is movably arranged in the housing 21. The negative pressure pick-up probe 3 is set to be conventional and grasps the cloth piece according to the principle of negative pressure adsorption. Since the cloth piece itself is soft, when the cloth piece is adsorbed by the negative pressure pick-up probe 3, the middle part of the cloth piece will naturally collapse. Therefore, it is necessary to apply a certain tension to the cloth piece to make the cloth piece expand into a flat state. Therefore, a tensioning component for driving the negative pressure pick-up probe 3 to move is arranged in the housing 21.

[0032] Reference Figure 4 and Figure 5 As shown in Figure 5 , a pushing cavity 211 is formed in the housing 21. The tensioning assembly includes a driving shaft 22, on which a spiral cam 221 is fixedly arranged. The spiral cam 221 includes a spiral part 224 and a rotating part 223. The rotating part 223 is fixed to the driving shaft 22, and the spiral part 224 is arranged as a spiral-shaped tooth piece. A probe roller 31 is fixedly arranged at the top of the negative pressure pickup probe 3, and the probe roller 31 is in transmission engagement with the spiral cam 221. A limiting part 311 is arranged on the probe roller 31, and the limiting part 311 is in snap-fit with the spiral part 224. Specifically, the limiting part 311 is a plate arranged at both ends of the probe roller 31. This setting forms a groove at the place where the probe roller 31 meshes with the spiral part 224, and the limiting part 311 can make the probe roller 31 more firmly snap-fitted with the spiral part 224. A driving cavity 212 is also formed in the housing 21, and a driving motor 213 is arranged in the driving cavity 212. The driving shaft 22 is driven by the driving motor 213 to rotate, so as to drive the spiral cam 221 to rotate. When the spiral part 224 rotates, it can drive the probe roller 31 to rotate along the spiral-shaped surface of the spiral part 224 itself, and under the action of the limiting part 311, the probe roller 31 is snap-fitted with the spiral part 224 to maintain the stability of the transmission. An idle wheel 225 is also arranged on the driving shaft 22. The idle wheel 225 is arranged adjacent to the spiral cam 221, and the idle wheel 225 is arranged on the side with a lower height of the spiral part 224. One end of the idle wheel 225 is fixedly provided with an anti-detachment plate 226, and the height of the anti-detachment plate 226 is higher than the surface of the idle wheel 225. The idle wheel 225 is rotatably connected to the driving shaft 22. This setting makes the idle wheel 225 not driven by the driving shaft 22, and the setting of the anti-detachment plate 226 can prevent the probe roller 31 from falling off the idle wheel 225.

[0033] Reference Figure 2 and Figure 3 As shown in Figure 3 , walking wheels 222 are rotatably arranged at both ends of the driving shaft 22. The walking wheels 222 are rotatably connected to the driving shaft 22 and can rotate relative to the driving shaft 22. Roller grooves 12 are formed at the top of the sliding frame 1 corresponding to the walking wheels 222, and the walking wheels 222 are installed in the roller grooves 12. By the rolling of the walking wheels 222 in the roller grooves 12, it is convenient for the operator to move the pickup head 10 along the sliding frame 1, so as to conveniently adjust the adsorption position according to the size of the cloth piece.

[0034] Reference Figure 4 and Figure 5, a spring chamber 215 is provided inside the housing 21. The tensioning assembly further includes a toggle lever 23. A toggle roller 231 is rotatably provided at one end of the toggle lever 23, and a toggle sleeve 232 is fixedly provided at the other end of the toggle lever 23. The negative pressure pickup probe 3 is slidably sleeved on the toggle sleeve 232. A return spring 233 is sleeved on the toggle lever 23, and the return spring 233 abuts against the inner wall of the spring chamber 215. The return spring 233 always pushes the toggle roller 231 in a direction away from the negative pressure pickup probe 3 by its own elastic force. A positioning groove 13 is further provided on the sliding frame 1. The positioning groove 13 is provided along the length direction of the sliding frame 1. Specifically, the positioning groove 13 is provided on the side wall of the sliding groove 11. A positioning block 14 is provided in the positioning groove 13. The positioning block 14 includes a sliding portion 142 that can slide relative to the positioning groove 13. The sliding portion 142 is provided in a plate shape and is clamped in the groove of the positioning groove 13. The positioning block 14 further includes a clamping portion 143. The clamping portion 143 protrudes outside the positioning groove 13. The arrangement of the sliding portion 142 enables the sliding portion 142 to slide along the positioning groove 13, facilitating the adjustment of the position of the positioning block 14. A clamping groove 1431 is provided on the clamping portion 143. The clamping groove 1431 can cooperate with the toggle roller 231 for clamping. A slope 1432 connected to the clamping groove 1431 is further provided on the clamping portion 143. The arrangement of the slope 1432 enables the toggle roller 231 to roll along the slope 1432 into the clamping groove 1431 conveniently. After the positioning block 14 is adjusted to the proper position, the sliding portion 142 is fixed by bolts.

[0035] Referring to Figure 4 , a moving groove 214 for the movement of the negative pressure pickup probe 3 is provided at the bottom of the housing 21. The arrangement of the moving groove 214 facilitates the movement of the negative pressure pickup probe 3.

[0036] The implementation principle of the embodiment of this application is as follows: The palletizing device for square cloth pieces provided in this application is applicable to square cloth pieces of any size. After the square cloth pieces are cut, they are moved to the palletizing device through the conveying device. The horizontal moving mechanism drives the palletizing mechanism to move directly above the cloth pieces, and the lifting mechanism drives the palletizing mechanism to move downward. A plurality of sliding frames 1 move downward simultaneously, and a plurality of pickup heads 10 provided on the sliding frames 1 need to adsorb the cloth pieces simultaneously.

[0037] Before the pickup head 10 adsorbs the cloth piece, the operator needs to manually adjust the position of the pickup head 10 on the sliding frame 1. According to the size of the cloth piece, the positioning block 14 is manually slid so that the distance between two positioning blocks 14 on the same sliding frame 1 is equal to one side length of the cloth piece. If the cloth piece is square, the distance between all positioning blocks 14 is adjusted according to one size. If the cloth piece is rectangular, the distance between the two positioning blocks 14 is adjusted according to the side length. After adjusting the spacing of the positioning blocks 14, manually slide the pickup head 10. When the pickup head 10 is in the initial state, under the elastic force of the reset spring 233, the toggle rod 23 is elastically driven to always move in the direction away from the negative pressure pickup probe 3, so that the position of the negative pressure pickup probe 3 in the natural state is closest to the reset spring 233. Therefore, the probe roller 31 is engaged with the idle wheel 225 in the natural state. At this time, the negative pressure pickup probe 3 is in the idle state. In this state, the operator pushes the pickup head 10 to slide along the sliding frame 1 without affecting the negative pressure pickup probe 3.

[0038] When the pickup head 10 is pushed to contact the positioning block 14, the toggle roller 231 will roll along the slope 1432 of the positioning block 14 toward the engaging groove 1431, and finally be engaged by the engaging groove 1431 and make a clicking sound, prompting the operator that the pickup head 10 has entered the working state. After the pickup head 10 enters the working state, the toggle rod 23 will be pushed after the toggle roller 231 is engaged with the engaging groove 1431, so that the probe roller 31 is pushed from the original state of engagement with the idle wheel 225 to engagement with the spiral portion 224, and the negative pressure pickup probe 3 is in a state of waiting to be driven.

[0039] After the pickup head 10 enters the working state, the lifting mechanism drives all the sliding frames 1 to move downward at the same time, so that the negative pressure pickup probe 3 contacts the surface of the cloth piece at the same time and adsorbs the cloth piece. Then, it is lifted upward under the drive of the lifting mechanism. During the lifting process, the middle part of the cloth piece will collapse. At this time, the driving motor 213 is controlled to drive the spiral cam 221 to rotate. When the spiral cam 221 rotates, the toggle roller 231 will move along the spiral part 224, so that the negative pressure pickup probe 3 completes the movement path of expanding outward. For the cloth piece as a whole, the negative pressure pickup probes 3 evenly distributed around the cloth piece move around at the same time, and the cloth piece will be propped up and kept flat.

[0040] Since the setting of the spiral portion 224 enables the negative pressure pickup probe 3 to move steplessly during the outward movement, the moving length of each negative pressure pickup probe 3 can be controlled by the working duration of the driving motor 213 to avoid excessive movement of the negative pressure pickup probe 3.

[0041] After completing one transfer of the cloth piece, the spiral cam 221 can be reversed to reset the negative pressure pickup probe 3.

[0042] The above are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
