Another core of the present invention is to provide a loom including the automatic disengagement mechanism for a cloth roller.

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Please refer to Figures 1 to 3 , Figure 1 A schematic structural diagram of a specific implementation of the automatic disengagement mechanism for the cloth winding roller provided by the present invention; Figure 2 A cross-sectional schematic diagram of a specific implementation of the automatic disengagement mechanism for the cloth winding roller provided by the present invention; Figure 3 The present invention is a schematic diagram of the installation of a specific implementation of the automatic disengagement mechanism for the cloth rolling roller provided by the present invention.

[0026] The specific embodiment of the present invention provides an automatic disengagement mechanism for a cloth roller, comprising a first wall panel 1 and a second wall panel 2 arranged opposite to each other. In the specific embodiment, the first wall panel 1 is located on the left side of the front lower part of the inner side of the loom, and the second wall panel 2 is located on the right side of the front lower part of the inner side of the loom. Of course, the positions and arrangements of the two wall panels can also be adjusted according to the situation. A gap is provided between the first wall panel 1 and the second wall panel 2, and a cloth roller 3 is installed between the first wall panel 1 and the second wall panel 2. The cloth roller 3 is arranged horizontally and is used to wind the cloth. Among them, the two opposite side surfaces of the two wall panels are inner side surfaces, and the opposite side surfaces are outer side surfaces. The end of each component close to the two end wall panels is the outer end, and the end close to the center is the inner end.

[0027] The main driving shaft 4 is installed on the first wall panel 1 and is detachably connected to the first end of the cloth rolling roller 3. The supporting shaft 5 is installed on the second wall panel 2 and is detachably connected to the second end of the cloth rolling roller 3. The cloth rolling roller 3 is arranged horizontally, and the two ends of the cloth rolling roller 3 are detachably connected to the inner end of the main driving shaft 4 and the inner end of the support shaft 5, respectively, so that the cloth rolling roller 3 is stably installed between the first wall panel 1 and the second wall panel 2. At the same time, the cloth rolling roller 3 is rotated by rotating the main driving shaft 4.

[0028] A first driver and a first axial displacement mechanism are installed on the inner side of the first wall panel 1. The first driver can drive the first axial displacement mechanism to move axially to push the first end of the cloth rolling roller 3 to separate from the main driving shaft 4. A second driver and a second axial displacement mechanism are installed on the inner side of the second wall panel 2. The second driver can drive the second axial displacement mechanism to move axially to push the support shaft 5 to separate from or contact the second end of the cloth rolling roller 3.

[0029] During operation, the cloth rolling roller 3 is installed between the inner end of the main drive shaft 4 and the inner end of the support shaft 5. The cloth rolling roller 3 is driven to rotate by rotating the main drive shaft 4, and the cloth is wound on the cloth rolling roller 3. When the cloth length on the cloth rolling roller 3 reaches the cloth dropping requirement, the cloth is cut first, and then the second driver is started, so that the second axial displacement mechanism pushes the support shaft 5 to move outward, and the support shaft 5 is separated from the second end of the cloth rolling roller 3. Then the first driver is started, so that the first axial displacement mechanism pushes the cloth rolling roller 3 to move toward the second wall panel 2, and the first end of the cloth rolling roller 3 is separated from the main drive shaft 4. At this time, the cloth rolling roller 3 is completely separated from the inner end of the main drive shaft 4 and the inner end of the support shaft 5, and the cloth roll is transported away and a new cloth rolling roller 3 is put in. When installing a new cloth roller 3, the second drive is started, so that the second axial displacement mechanism pushes the support shaft 5 to move inward, and the support shaft 5 contacts and connects the second end of the cloth roller 3, and continues to push the cloth roller 3 to move toward the first wall panel 1, so that the first end of the cloth roller 3 contacts and connects the main drive shaft 4, and the installation of the cloth roller 3 is completed.

[0030] The axial displacement mechanism is moved axially by two drivers, so that the main drive shaft 4 and the support shaft 5 can be separated from or contact the two ends of the cloth winding roller 3, thereby realizing automatic disassembly and installation of the cloth winding roller 3, completing automatic and intelligent replacement of the cloth winding roller 3, reducing the labor intensity of the operator, simplifying the replacement operation, and improving work efficiency.

[0031] In the automatic disengagement mechanism of the cloth winding roller provided in the specific embodiment of the present invention, the first axial displacement mechanism includes a first fixed seat 6, a first driven cylinder 7 and a sleeve 8, wherein the first fixed seat includes a base plate and a cylinder arranged on the inner side of the base plate, the interior of the cylinder is hollow, the first driven cylinder 7 is a cylinder, the cylinder of the first fixed seat 6, the cylinder of the first driven cylinder 7, the sleeve 8 and the main drive shaft 4 are coaxially arranged, and when installed, the outer side of the base plate of the first fixed seat 6 is installed in contact with the inner side of the first wall panel 1, the main drive shaft 4 passes through the axial through hole inside the first fixed seat 6, the first driven cylinder 7 is sleeved on the outer periphery of the cylinder of the first fixed seat 6, the outer end of the first driven cylinder 7 is connected to the first driver, and the sleeve 8 is sleeved on the outer periphery of the inner end of the first driven cylinder 7. At the same time, the first fixing seat 6 is provided with an axially extending first straight groove, the first driven cylinder 7 is provided with a spirally extending first inclined groove, the sleeve 8 is provided with a first fixing hole, and the first positioning pin 9 passes through the first fixing hole, the first inclined groove and the first straight groove in sequence. When working, the first driver rotates the first driven cylinder 7, and the first positioning pin 9 located in the first inclined groove moves relative to the first driven cylinder 7. Since the first positioning pin 9 does not produce circumferential rotation, the first positioning pin 9 only moves axially along the first straight groove, and then the first positioning pin 9 pushes the sleeve 8 to move axially, so that the sleeve 8 pushes the cloth rolling roller 3 to move axially toward the second wall panel 2. The first positioning pin 9 is fastened to the outer circle of the sleeve 8 by a nut.

[0032] Furthermore, the inner end of the main drive shaft 4 protrudes from the inner end of the first driven cylinder 7, and a support cylinder 10 is installed on the outer periphery of the inner end of the main drive shaft 4, and a drive key 11 is installed on the inner end face of the main drive shaft 4. The main drive shaft 4 and the support cylinder 10 are connected by a flat key, and the drive key 11 is fastened in the installation groove provided on the inner end face of the main drive shaft 4 by a screw. The first end face of the cloth winding roller 3 is provided with a first connecting hole, and the support cylinder 10 is inserted into the first connecting hole, and the drive key 11 is embedded in the keyway at the bottom of the first connecting hole, which can realize the transmission of the main drive shaft 4, and the inner end face of the sleeve 8 is aligned with the first end face of the cloth winding tube. And the support cylinder 10 can limit the axial movement of the first driven cylinder 7, so that the first driven cylinder 7 can only rotate but not translate.

[0033] In the automatic disengagement mechanism of the cloth rolling roller provided in the specific embodiment of the present invention, the second axial displacement mechanism includes a second fixed seat 12 and a second driven cylinder 13, wherein the second fixed seat 12 includes a base plate and a cylinder arranged on the inner side of the base plate, the cylinder is hollow inside, the second driven cylinder 13 is a cylinder, the cylinder of the second fixed seat 12, the cylinder of the second driven cylinder 13 and the support shaft 5 are coaxially arranged, when installed, the outer side of the base plate of the second fixed seat 12 is installed in contact with the inner side of the second wall panel 2, the support shaft 5 passes through the axial through hole inside the second fixed seat 12, the second driven cylinder 13 is sleeved on the outer periphery of the cylinder of the second fixed seat 12, and the outer end of the second driven cylinder 13 is connected to the second driver.

[0034] Coaxially arranged, when installed, the outer side of the bottom plate of the first fixed seat 6 is installed in contact with the inner side of the first wall panel 1, the second fixed seat 12 is provided with an axially extending second straight groove, the second driven cylinder 13 is provided with a spirally extending second inclined groove, and the support shaft 5 is provided with a second fixing hole, and the second positioning pin 14 passes through the second inclined groove, the second straight groove and the second fixing hole in sequence. When working, the second driver rotates the second driven cylinder 13, and the second positioning pin 14 located in the second inclined groove moves relative to the second driven cylinder 13. Since the second positioning pin 14 will not generate circumferential rotation, the second positioning pin 14 will only move axially along the second straight groove, and then the second positioning pin 14 pushes the support shaft 5 to move axially, so that the support shaft 5 moves axially inward or outward.

[0035] Furthermore, a support seat 15 is installed at the inner end of the support shaft 5, a bearing 16 and an elastic retaining ring 17 are installed on the support seat 15, a second connection hole is provided on the second end face of the cloth winding roller 3, and the support seat 15 is inserted into the second connection hole. Preferably, a guide slope is provided at the inner end of the support cylinder 10 and the inner end of the support seat 15 to form a conical guide structure, so that the support cylinder 10 and the support seat 15 can smoothly enter the first connection hole and the second connection hole.

[0036] Specifically, the first driver is a first stepper motor 18, the output shaft of the first stepper motor 18 is equipped with a synchronous pulley, the first driven cylinder 7 is provided with a driven pulley, and the first driven cylinder 7 is driven by a first synchronous belt 19. The second driver is a second stepper motor 20, the output shaft of the second stepper motor 20 is equipped with a synchronous pulley, the second driven cylinder 13 is provided with a driven pulley, and the second stepper motor 20 drives the second driven cylinder 13 through a second synchronous belt 21.

[0037] A first bracket is installed inside the first wall panel 1, and an axially extending long slot is provided on the first bracket, and two first proximity switches 22 arranged in parallel are installed at both ends of the long slot. A second bracket is installed inside the second wall panel 2, and an axially extending long slot is provided on the second bracket, and two second proximity switches 23 arranged in parallel are installed at both ends of the long slot. The two extreme positions of the cloth rolling roller 3 are judged by the two proximity switches, thereby ensuring accurate control of the movement.

[0038] On the basis of the automatic disengagement mechanism of the cloth rolling roller provided in the above-mentioned specific embodiments, a first bracket 24 is installed on the inner side of the first wall panel 1, the outer end of the first bracket 24 is located below the first axial displacement mechanism, and the inner end of the first bracket 24 is provided with an arc groove for supporting the first end of the cloth rolling roller 3, and a second bracket 25 is installed on the inner side of the second wall panel 2, the outer end of the second bracket 25 is located below the second axial displacement mechanism, and the inner end of the second bracket 25 is provided with an arc groove for supporting the second end of the cloth rolling roller 3. Specifically, the bracket is a horizontally arranged plate, the outer end of the plate is provided with an outer flange folded downward, the outer flange is connected to the inner side of the corresponding wall panel, the inner end of the plate is provided with an inner flange folded upward, the upper edge of the inner flange is provided with an arc groove, and a rib plate can also be provided under the plate. Each component can be connected by bolts, or other connection methods can be adopted, all of which are within the protection scope of the present invention.

[0039] The specific working process is as follows: during normal operation, the cloth roller 3 is installed between the support tube 10 and the support seat 15. The power is transmitted to the support tube 10 through the main drive shaft 4, and then transmitted to the cloth roller 3 through the drive key 11. The cloth roller 3 rotates, and the support seat 15 rotates with the help of the bearing 16, thereby driving the cloth surface to be continuously wound on the cloth roller 3. When the cloth length of the cloth roller 3 reaches the cloth drop requirement, it is only necessary to cut the cloth at this time, and control the first synchronous belt 19 and the second stepper motor 20 on the left and right sides to drive the entire mechanism to disengage the cloth roller 3 from the two side mechanisms. After disengagement, the ends of the cloth roller 3 will fall on the arc grooves of the first bracket 24 and the second bracket 25 respectively, waiting for the cloth to be transported away. During the entire action process, the first proximity switch 22 and the second proximity switch 23 are responsible for detecting the two extreme positions of the movement, thereby ensuring precise control of the movement.

[0040] When disassembling, first let the second stepper motor 20 operate, and the power of the second stepper motor 20 is transmitted to the second driven cylinder 13 through the synchronous pulley and the second synchronous belt 21. At this time, the second driven cylinder 13 can only rotate due to the positioning function of the positioning plate. At this time, the second inclined groove on it will drive the second positioning pin 14 to move rightward in the second straight groove of the second fixed seat 12, thereby driving the support shaft 5 and the support seat 15 to move rightward, so that the support seat 15 is disengaged from the second end of the cloth roller 3 and falls on the second bracket 25. At this time, the second stepper motor 20 remains stationary, and waits for the cloth roll to be transported away and a new cloth roller 3 is put in.

[0041] Then the first stepper motor 18 is controlled to move, and the power is transmitted to the first driven cylinder 7 through the synchronous pulley and the first synchronous belt 19. At this time, the first driven cylinder 7 can only rotate due to the positioning effect of the support cylinder 10. At this time, the first inclined groove on the first driven cylinder 7 will drive the first positioning pin 9 to move to the right in the first straight groove of the first fixed seat 6, thereby driving the sleeve 8 to move to the right. The sleeve 8 will hit the end face of the cloth roller 3 and push the entire cloth roller 3 to the right. Since the support cylinder 10 is fixed on the main drive shaft 4, as the cloth roller 3 moves to the right, the cloth roller 3 will disengage from the support cylinder 10 and fall on the first bracket 24. At this time, the first stepper motor 18 is controlled to move in the opposite direction to reset the sleeve 8 and wait for the next disengagement action to be executed.

[0042] During installation, the left and right ends of the cloth roll 3 fall onto the first bracket 24 and the second bracket 25 respectively, waiting to be transported away. When the cloth roll is transported away, a new cloth roll 3 can be put into the first bracket 24 and the second bracket 25, and then the second stepper motor 20 is controlled to move in the opposite direction, so that the support seat 15 is inserted into the second connection hole of the cloth roll 3, and the first connection hole of the cloth roll 3 is pushed onto the conical surface of the support tube 10, so that the cloth roll 3 is coaxial with the two side mechanisms, and the cloth is wound onto the cloth roll 3. As the main drive shaft 4 continues to rotate, the drive key 11 will be inserted into the keyway on the end face of the cloth roll 3, and a new winding process will be initiated.

[0043] In addition to the above-mentioned cloth roller automatic disengagement mechanism, a specific embodiment of the present invention further provides a loom including the above-mentioned cloth roller automatic disengagement mechanism. For the structures of other parts of the loom, please refer to the prior art and will not be described in detail herein.
