Referring to fig. 1, an embodiment of the present invention provides a feeding device 100 for sequentially conveying materials obtained from an upstream station to a downstream device. In the following embodiments, the feeding device 100 is applied to a spooling process in the textile industry, and a lifting device 200 for lifting the material cylinders one by one from bottom to top is arranged on one side of the feeding device 100.

As shown in fig. 1 to 3, the feeding device 100 includes a feeding housing 20 and a feeding mechanism 40, wherein the feeding housing 20 is used for accommodating materials and being transported to downstream by the feeding mechanism 40.

It is defined that an end of the loading housing 20 away from the lifting device 200 (i.e., the left side in fig. 1) is a front end of the loading housing 20, an end of the loading housing 20 close to the lifting device 200 (i.e., the right side in fig. 1) is a rear end of the loading housing 20, a side of the loading housing 20 away from the screen in fig. 1 is a right side of the loading housing 20, and a side of the loading housing 20 close to the screen in fig. 1 is a left side of the loading housing 20.

Specifically, the loading housing 20 has a loading cavity 25, and the loading housing 20 includes a housing bottom wall 21, a housing front wall 24, a housing left side wall 22, and a housing right side wall 23. The case bottom wall 21 extends obliquely downward from the front end of the charging case 20 to the rear end of the charging case 20 in the first direction. The housing left side wall 22 and the housing right side wall 23 are disposed opposite to each other in the second direction and in parallel to the left and right sides of the housing bottom wall 21, and the housing front wall 24 is disposed at the front end of the housing bottom wall 21 that is higher in height in the first direction and is connected between the housing left side wall 22 and the housing right side wall 23. So, casing diapire 21, casing left side wall 22, casing antetheca 24 and casing right side wall 23 delimit the material loading chamber 25 that forms the material that is used for storing jointly, and casing diapire 21 runs through along the third direction and has seted up the spread groove that communicates material loading chamber 25 and external environment.

The first direction is an X direction in fig. 1, the second direction is a Y direction in fig. 1, the third direction is a Z direction in fig. 1, the first direction and the second direction are both parallel to a horizontal plane, the third direction is parallel to a vertical direction, and the first direction, the second direction and the third direction are pairwise perpendicular.

Further, the end of the feeding cavity 25, which is provided with the front wall 24 of the housing, is a feeding end, the end of the feeding cavity 25, which is far away from the front wall 24 of the housing, is a discharging end, a hollow groove is formed in the end, which is close to the front wall 24 of the housing, of the right side wall 23 of the housing to connect with an upstream station, and a lifting device 200 is arranged on the opposite side of the feeding cavity 25 and the front wall 24 of the housing in the first direction. In this way, the feeding end and the discharging end of the feeding cavity 25 are opposite to each other in the first direction, and the feeding device 100 can receive the materials conveyed by the upstream station and then convey the materials to the downstream lifting device 200 in order, so as to realize the conveying of the materials.

The feeding mechanism 40 is located right below the feeding housing 20, and the feeding mechanism 40 includes a mounting base 43, at least two lifting driving members 45, and at least two feeding portions 41. The installation base 43 is arranged right below the connecting groove of the bottom wall 21 of the casing, the lifting driving member 45 is installed on one side of the installation base 43 facing the feeding casing 20, and at least two lifting driving members 45 are arranged at intervals along the first direction. At least part of the feeding parts 41 are correspondingly arranged at one end of the lifting driving part 45 facing the feeding shell 20, at least two feeding parts 41 are sequentially arranged along the material conveying direction, and the lifting driving part 45 can drive the feeding parts 41 to do lifting motion in the vertical direction. Specifically, the feeding portions 41 are sequentially arranged in a direction from the feeding end to the discharging end of the feeding housing 20 along the first direction.

So, the spread groove that material loading portion 41 seted up on through casing diapire 21 stretches into material loading chamber 25, two at least material loading portions 41 arrange in proper order along the first direction, lift driving piece 45 can drive at least part material loading portion 41 and go up and down in the third direction, so that every two adjacent material loading portions 41 can go up and down relatively in vertical direction in order to change the difference in height between the two, thereby allow or prevent the material and remove in material loading chamber 25, and then realized the automatic current-limiting transport of material, effectively avoided the material to pile up, and the production efficiency is improved.

Specifically, the feeding device 100 has a feeding mode allowing the material to move from the feeding end to the discharging end and a feeding stopping mode preventing the material from moving from the feeding end to the discharging end, and the feeding device 100 can be selectively switched between the feeding mode and the feeding stopping mode, so that the feeding speed of the material is limited while the material is controlled to be smoothly fed, and the material is prevented from being accumulated at the discharging end of the feeding cavity 25.

When the feeding device 100 is in the feeding mode, at least two feeding portions 41 form a step structure with a downward trend in a direction from the feeding end to the discharging end, and the material automatically moves from the feeding end to the discharging end along the feeding surface under the action of gravity.

When the feeding device 100 is in the stop feeding mode, in at least two adjacent feeding portions 41, the height of the feeding portion 41 close to the feeding end of the feeding cavity 25 relative to a horizontal plane is lower than the height of the feeding portion 41 close to the discharging end relative to the same horizontal plane, so that the material is blocked by the feeding portion 41 close to the discharging end of the feeding cavity 25 and cannot move towards the discharging end along the first direction, and the conveying of the material is stopped.

Further, the loading part 41 has a supporting surface for supporting the material and communicating with the loading chamber 25, and the supporting surface extends obliquely downward relative to the horizontal in the direction in which the feeding end points to the discharging end, so that the material on the supporting surface can roll down gradually in the direction in which the feeding end points to the discharging end under the action of gravity.

Specifically, in one embodiment, the feeding mechanism 40 includes two feeding portions 41, the two feeding portions 41 are arranged along a direction in which the feeding end points to the discharging end, and the supporting surfaces of the two feeding portions 41 are smooth planes extending obliquely downward along the direction in which the feeding end points to the discharging end, so that the material smoothly moves along the supporting surfaces.

In the above embodiment, when the loading device 100 is in the loading mode, the height of the loading part 41 near the feeding end of the loading chamber 25 is higher than the height of the other loading part 41, so that the material moves in the first direction from the feeding end of the loading chamber 25 to the discharging end of the loading chamber 25 under the action of gravity.

When the feeding device 100 is in the stop feeding mode, the height of the feeding part 41 close to the feeding end of the feeding cavity 25 is lower than that of the other feeding part 41, so that the material on the feeding part 41 close to the feeding end of the feeding cavity 25 is blocked by the side wall of the other feeding part 41 and cannot move continuously, and the conveying of the material is stopped.

In other embodiments, the feeding mechanism 40 includes three feeding portions 41, the feeding portion 41 at the nearest discharging end is fixedly disposed relative to the feeding chamber 25, and the supporting surface of the feeding portion 41 is configured as an arc-shaped surface extending downward relative to the material conveying direction, and the supporting surface of the remaining feeding portion 41 is a smooth surface extending downward relative to the material conveying direction. So, the supporting surface that is the arcwall face can make the material can adjust the gesture more high-efficiently and make the central axis of self be on a parallel with the second direction to practice thrift the time that delays because of adjusting the material gesture.

In the above embodiment, when the loading device 100 is in the loading mode, the heights of the three loading portions 41 are gradually reduced along the direction in which the feeding end of the loading chamber 25 points to the discharging end, so that the material moves from the feeding end of the loading chamber 25 to the discharging end of the loading chamber 25 along the first direction.

When the feeding device is in the stop feeding mode, the heights of the three feeding portions 41 in the direction in which the feeding end of the feeding cavity 25 points to the discharging end gradually increase, so that the material located near the feeding end of the feeding cavity 25 cannot move on to the next feeding portion 41, and the conveying of the material is stopped.

It will be appreciated that the number of loading portions 41 is not limited, so that the material conveying process can be adjusted more precisely. The supporting surface of the feeding portion 41, which is an arc surface, is preferably an arc surface, and may be a curved surface, a continuous derivative arc, a polygonal shape with edges, or the like, as required.

In some embodiments, in order to control the ascending and descending of the loading part 41, the loading device 100 further includes a first detection mechanism 60, the first detection mechanism 60 is installed on a cavity wall of the loading cavity 25, the first detection mechanism 60 is used for detecting the amount of the material in the discharging end, and the loading part 41 is configured to ascend or descend according to the detection result of the first detection mechanism 60.

Specifically, in some embodiments, the first detecting mechanism 60 is located at the discharging end of the feeding cavity 25 and includes a grating sensor emitting unit 61 and a grating sensor receiving unit 63, the grating sensor emitting unit 61 is installed on one of the left side wall 22 or the right side wall 23 of the housing, the grating sensor receiving unit 63 is installed on the other one of the left side wall 22 or the right side wall 23 of the housing, both the grating sensor emitting unit 61 and the grating sensor receiving unit 63 extend lengthwise along the third direction, the grating sensor emitting unit 61 and the grating sensor receiving unit 63 are disposed opposite to each other in the second direction, and the grating sensor emitting unit 61 can emit light to the grating sensor receiving unit 63.

When the light is received by the grating sensor receiving unit 63, it indicates that the material at the discharging end of the feeding cavity 25 is lower than the threshold, so that the feeding device 100 is in the feeding mode, and the height of the feeding portion 41 close to the discharging end of the feeding cavity 25 is reduced relative to the height of the remaining feeding portions 41 until the height of the feeding portion 41 in the direction pointing to the discharging end along the feeding end of the feeding cavity 25 is gradually reduced to form a step structure, so that the material moves from the feeding surface to the discharging end.

When the light is not received by the receiving unit 63 of the optical grating sensor, it indicates that the material at the discharging end of the feeding cavity 25 exceeds the threshold, and therefore the feeding device 100 is in the feeding stop mode, the height of the feeding portion 41 close to the discharging end of the feeding cavity 25 is increased relative to the heights of the other feeding portions 41, and at this time, in at least two adjacent feeding portions 41, the height of the feeding portion 41 close to the feeding end is lower than the height of the feeding portion 41 close to the feeding end, so that the material is blocked by the feeding portion 41 close to the discharging end and cannot move, and thus the conveying of the material is stopped to avoid the material from being blocked at the discharging end.

In some embodiments, in order to further avoid material accumulation in the feeding cavity 25, the feeding device 100 further includes at least two sets of second detecting mechanisms 70, where the at least two sets of second detecting mechanisms 70 are installed on the cavity wall of the feeding cavity 25 and located at an end of the feeding cavity 25 away from the discharging end, and the at least two sets of second detecting mechanisms 70 are arranged at intervals in the first direction, and the second detecting mechanisms 70 are configured to detect the amount of the material on the feeding portion 41, so as to control the material conveying speed of the upstream station, and further control the amount of the material conveyed to the feeding end to be maintained at a preset value, and a specific value of the preset value can be set as required.

Specifically, in some embodiments, the feeding device 100 further includes two sets of second detecting mechanisms 70, where each set of second detecting mechanisms 70 is disposed corresponding to one feeding portion 41, so as to detect whether there is material on each feeding portion 41. Each set of the second detecting mechanism 70 includes a photoelectric proximity switch 71 and a receiving board 73, the photoelectric proximity switch 71 is mounted on the left side wall 22 of the housing, the receiving board 73 is mounted on the right side wall 23 of the housing, the photoelectric proximity switch 71 and the receiving board 73 are disposed opposite to each other in the second direction, and the photoelectric proximity switch 71 can emit light to the receiving board 73.

When any receiving plate 73 receives the light sent by its corresponding photoelectric proximity switch 71, it indicates that there is less material in the loading chamber 25, so the upstream station delivers the material to the loading chamber 25. When all the receiving plates 73 do not receive the light sent by the photoelectric proximity switch 71, it indicates that more materials are in the feeding cavity 25, and therefore the upstream station stops conveying the materials to the feeding cavity 25, so that the materials entering the feeding end of the feeding cavity 25 are kept at the preset value, accumulation of too many materials is avoided, and influence on feeding efficiency due to too few materials is also avoided.

The feeding device 100 can be matched with an upstream process, and stable and orderly conveying of materials is realized through the liftable feeding part 41. In addition, the material feeding part 41 can efficiently adjust the posture of the material while conveying the material, thereby facilitating the material conveying in the downstream process and effectively improving the conveying efficiency.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
