Description

Technical Field

[0001] The utility model belongs to an automatic bag mouth rolling machine, in particular to a material unloading mechanism of the automatic bag mouth rolling machine. Background Art

[0002] Existing sewing equipment is only suitable for conventional sewing work. For more complicated operations such as pocket hemming sewing, manual work is still required. However, a finished garment usually has multiple pockets, and it obviously takes a lot of manpower to meet production needs. At the same time, the size consistency of manual hemming is poor. Not only are the sizes of pockets rolled out by different people different, but even the sizes of pockets rolled out by the same person are inconsistent. This is unacceptable for the preparation of ready-made clothes, especially high-end clothing.

[0003] To this end, for example, the Chinese utility model patent "An automatic device for pocket hemming and sewing", whose patent number is ZL201520623164.X (authorization announcement number is CN205000098U) discloses an automatic device, which includes a machine base, on which is provided a horizontal working platform; a conveying module, which is installed on the machine base and can drive the fabric to move along the working platform; a hemming mold and a sewing module, which are arranged in sequence along the movement direction of the fabric, wherein the hemming mold is used to hem the fabric, and the sewing module is used to sew the fabric after hemming; a material receiving module, which is arranged at the tail end of the conveying module, and is used to recycle the fabric that has completed hemming and sewing.

[0004] The pocket hemming mechanism realizes the automatic hemming and material collection of the pocket. The material collection bracket in the material collection module (material unloading mechanism) is the main bearing structure of the device, on which a loading platform for carrying the cloth to be collected is installed. The loading platform can rotate around its axis to achieve the purpose of rotary collection. Compared with the traditional stacking method, the cloth is separated from each other during the collection process, thereby effectively avoiding the undesirable conditions such as cloth wrinkles and deformation caused by squeezing each other. However, the cloth falling on the loading platform is prone to wrinkles and deformation.

[0005] Therefore, it is necessary to further improve the existing blanking mechanism. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a material unloading mechanism of an automatic bag-rolling machine which can make the cloth fall smoothly in view of the current status of the above-mentioned prior art.

[0007] The technical solution adopted by the utility model to solve the above technical problems is: a material unloading mechanism of an automatic bag roll mouth machine, including: a material receiving mechanism for receiving fabrics; characterized in that it also includes:

[0008] An anti-withdrawal mechanism, which is located above the material receiving mechanism and has a movable end that can move up and down;

[0009] A movable plate for at least partially positioning the cloth thereon, wherein the movable plate is located upstream of the material receiving mechanism along the conveying direction of the cloth, and is arranged to be able to approach or move away from the material receiving mechanism, and the movable plate has the following two states: in a first state, the movable plate is partially located between the material receiving mechanism and the anti-withdrawal mechanism, and the movable end can move downward to press against the cloth on the receiving plate; in a second state, the receiving plate moves in a direction away from the material receiving mechanism to be located beside the material receiving mechanism.

[0010] There are many ways to achieve the movement of the movable plate, which can be manual or actively driven by a driving mechanism. However, from the perspective of reliability, it is preferably also provided with a driving mechanism for driving the movable plate, and the power output end of the driving mechanism is connected to the movable plate drive.

[0011] There are various structural forms of the driving mechanism, but preferably, the driving mechanism includes a driver, a screw rod and a nut, the screw rod extends along the movement direction of the movable plate, and the nut is threadedly connected to the screw rod and connected to the movable plate.

[0012] In order to realize the movement of the movable plate more reliably and smoothly, the driving mechanism has two groups, and is arranged at intervals along a direction intersecting the moving direction of the movable plate.

[0013] Preferably, a sensor for sensing whether there is cloth on the movable plate is provided on the side of the anti-withdrawal mechanism away from the material receiving mechanism, and the signal output end of the sensor is electrically connected to the controller, and the controller is electrically connected to the driver, so as to control the driver to act according to the sensor sensing the presence of cloth. In this way, when the sensor senses that there is cloth on the movable plate, a signal is transmitted to the controller, and the controller controls the driver to drive the movable plate to move to the first state.

[0014] Preferably, it also includes a workbench for receiving the cloth, the movable plate is located below the workbench, a side of the workbench is provided with an escape opening for the cloth to be partially located therein, the movable plate is provided with a pushing mechanism located above the workbench at a position corresponding to the escape opening, and the power output end of the pushing mechanism has a state of moving downward to pass through the escape opening to press the cloth against the movable plate. In this way, the driving mechanism is prevented from occupying the space above the workbench.

[0015] Preferably, the pushing mechanism is a push rod cylinder.

[0016] Preferably, it also includes an extension rod extending along the moving direction of the movable plate, the extension rod is located on the workbench and installed on the workbench, the anti-withdrawal mechanism includes a push rod motor and an elastic member, the movable end is located on the push rod of the push rod motor, and the push rod motor and the extension rod are connected by the elastic member. In this way, the movable end of the push rod motor presses the cloth on the movable plate, and when the movable plate moves away from the material receiving mechanism, the movable plate is prevented from moving with the cloth, and the presence of the elastic member realizes flexible pressing, reduces the friction between the cloth and the movable plate, and when the movable plate completely leaves the cloth, the cloth falls on the material receiving mechanism.

[0017] Preferably, a sensor for sensing whether there is cloth on the movable plate is disposed on the side of the anti-withdrawal mechanism away from the material receiving mechanism, the sensor is located on the extension rod, and the signal output end of the sensor is electrically connected to the controller, and the controller is electrically connected to the driver, so as to control the driver to act according to the sensor sensing the presence of cloth. In this way, when the sensor senses that there is cloth on the movable plate, a signal is transmitted to the controller, and the controller controls the driver to drive the movable plate to move to the first state.

[0018] In order to protect the sensor and the anti-withdrawal mechanism, a cover shell is arranged on the extension rod to cover the periphery of the sensor and the anti-withdrawal mechanism.

[0019] Compared with the prior art, the advantages of the utility model are: in the unloading mechanism, the movable plate drives the cloth to move toward the material receiving mechanism (i.e., move downstream) to the first state, and the movable end of the anti-withdrawal mechanism moves downward to press the cloth. When the movable plate moves in the direction away from the material receiving mechanism (i.e., moves upstream), since the movable end presses the cloth, the cloth will not move upstream with the movable plate. When the movable plate completely leaves the cloth, it is in the second state, and the cloth falls on the material receiving mechanism. At this time, the cloth falls vertically, which reduces the occurrence of wrinkles, makes it smoother, reduces the tediousness brought about by subsequent manual leveling, reduces costs, and can better meet the needs.

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 5 As shown, the unloading mechanism of the automatic bag roll mouth machine of this embodiment includes a workbench 5 for receiving the cloth 9, a material receiving mechanism 1, an anti-withdrawal mechanism 2, a movable plate 3, a driving mechanism 4 and a pushing mechanism. Among them, the material receiving mechanism 1 is used to receive the cloth 9. The aforementioned material receiving mechanism 1 adopts the loading platform in the background technology, and will not be described in detail in this embodiment. The cloth 9 in this embodiment is a bag.

[0027] The anti-withdrawal mechanism 2 is arranged on the workbench 5 and is located above the material receiving mechanism 1, and has a movable end 211 that can move up and down. Specifically, an extension rod 52 extending along the movement direction of the movable plate 3 is installed above the workbench 5. Figure 5 As shown, the anti-withdrawal mechanism 2 includes a push rod motor 21 and an elastic member 22, the movable end 211 is located on the push rod of the push rod motor 21, and the push rod motor 21 and the extension rod are connected through the elastic member 22. The elastic member is a spring.

[0028] The movable plate 3 is used for a part of the cloth 9 to be located thereon. In this embodiment, along the conveying direction of the cloth 9, the movable plate 3 is located upstream of the receiving mechanism 1, and can be close to or away from the receiving mechanism 1 under the drive of the driving mechanism 4. Specifically, the movable plate 3 is located below the workbench 5, and a side of the workbench 5 is provided with an escape opening 51 for a part of the cloth to be located therein. The movable plate 3 is provided with a pushing mechanism located above the workbench 5 at a position corresponding to the escape opening 51. The aforementioned pushing mechanism is a push rod cylinder 6, which is installed on the movable plate 3 through a vertically arranged support rod 31, and the lower end of the support rod 31 passes through the escape opening 51. The power output end of the pushing mechanism has a state of moving downward to pass through the escape opening 51 to make the cloth 9 press against the movable plate 3. In this way, when the movable plate 3 moves downstream, the power output end of the pushing mechanism makes the cloth press against the movable plate 3, and at this time, the cloth 9 will be driven to move downstream together. When the movable plate approaches or moves the material receiving mechanism 1, the movable plate 3 has the following two states: in the first state, the movable plate 3 is partially located between the material receiving mechanism 1 and the anti-withdrawal mechanism 2, and the movable end 211 can move downward to press the cloth on the receiving plate; in the second state, the receiving plate moves away from the material receiving mechanism 1 to the side of the material receiving mechanism 1.

[0029] The driving mechanism 4 is used to drive the movable plate 3 to move, and the power output end of the driving mechanism 4 is connected to the movable plate 3. There are two groups of driving mechanisms 4, and they are arranged at intervals along the direction intersecting the moving direction of the movable plate 3. The two groups of driving mechanisms 4 have the same structure, and one group is used as an example for description below. The driving mechanism 4 includes a driver, a screw rod 41 and a nut 42. The screw rod 41 extends along the moving direction of the movable plate 3, and the nut 42 is threadedly connected to the screw rod 41 and connected to the movable plate 3.

[0030] A sensor 8 for sensing whether there is cloth 9 on the movable plate 3 is arranged on the side of the anti-withdrawal mechanism 2 away from the material receiving mechanism 1. The sensor 8 is located on the extension rod 52, and the signal output end of the sensor 8 is electrically connected to the controller, and the controller is electrically connected to the driver, so that the driver is controlled to act according to the sensor 8 sensing the presence of cloth 9.

[0031] In addition, a cover 7 is disposed on the extension rod 52 and covers the sensor 8 and the anti-withdrawal mechanism 2 .
