Detailed Description

The technical solutions of the present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1, the present application provides a shaft part supply device including: a base 10, wherein the base 10 is fixedly arranged on the frame; and a bracket 11, the bracket 11 being mounted to the base frame 10 and having a guide rail 12 for rollably or slidably supporting the shaft part. The guide rail 12 is used for carrying a shaft part, and when the shaft part is placed on the guide rail 12, the central axis direction of the shaft part is perpendicular to the extending direction of the guide rail 12. The bracket 11 is height-adjustably mounted to the base, and the guide rail 12 of the bracket 11 has a shaft part receiving end 13 and a shaft part supplying end 14 having a height lower than the shaft part receiving end 13, and preferably the heights of the shaft part receiving end 13 and the shaft part supplying end 14 are separately adjustable (as shown in fig. 2), thereby enabling adjustment of the inclination of the bracket 11 and the guide rail 12 with respect to the base 10. The shaft element supply device further comprises a stop mechanism having a stop state and a release state which are reciprocally switchable to effect stop and release of the shaft element sliding on the guide rail 12. Wherein, in the stopping state, the stopping mechanism is used for stopping the shaft part supported by the guide rail 12; in the released state, the stop mechanism allows the shaft element to roll under gravity on the guide rail 12 in the direction from the shaft element receiving end 13 towards the shaft element supplying end 14. The stopper mechanism is preferably provided in plural, and the plural stopper mechanisms respectively stopper the shaft parts rolling from the shaft part receiving end 13 toward the shaft part supplying end 14, thereby achieving the purpose of isolating the shaft parts and preventing the shaft parts from colliding with each other in the process of supplying the shaft parts in bulk.

The conventional shaft part supply device is characterized in that shaft parts are easy to roll, so that temporary storage and supply functions of the shaft parts are realized by using a structure such as a V-shaped support.

According to the technical scheme of the application, the characteristic that shaft parts are easy to roll is utilized, the shaft part supply device provides the guide rail 12 which can enable the shaft parts to slide or roll under the action of gravity, and the shaft parts rolling on the guide rail 12 are respectively stopped by the stopping mechanism with the stopping state and the releasing state which can be switched back and forth so as to prevent the shaft parts from colliding with each other, so that the shaft part supply device is simple in structure, low in cost and space-saving.

In the above shaft part supply device, the stopper mechanism may include: a stop member mounted to the base 10 or the bracket 11 to be movable up and down, the stop member having an upper stop position and a lower release position. When the stop is in the upper stop position, the stop stops the shaft element from rolling and stops in the stop position, and when the stop is in the lower release position, the shaft element can continue to roll in the direction of the shaft element supply end 14. The stop member can be automatically stopped and released by means of a sensor and a driver (such as an air cylinder). Or preferably, the stop mechanism does not need a sensor or a driver, and only by arranging a mechanism such as a lever or a hydraulic communicating device, the stop member is switched from the lower release position to the higher stop position by the self gravity after the shaft part passes through the stop member, so that the cost of the shaft part supply device is further saved.

As shown in fig. 3, the catching mechanism may include a catching lever 15, the catching lever 15 being disposed on the bracket 11 adjacent to the guide rail 12 in the extending direction of the guide rail 12, the catching lever 15 having a catching end 151 facing the shaft part receiving end 13, a supporting end 152 facing the shaft part supplying end 14, and a hinge portion 153 between the catching end 151 and the supporting end 152 and hinged to the bracket 11, the rotation axis of the hinge portion 153 being perpendicular to the extending direction of the guide rail 12. The hinge portion 153 may be a hinge manner in which a hinge hole of the stopper lever 15 is engaged with a hinge pin fixed to the bracket 11, or the hinge portion 153 may be in a form in which a hinge pin fixed to the stopper lever 15 is engaged with a hinge hole of the bracket 11. As shown preferably in fig. 1, the bracket 11 may include a pair of side plates 17,17 ' fixedly coupled to each other, the guide rail 12 being disposed between the pair of side plates 17,17 ', and the plurality of stopper levers 15 being disposed in pairs inside the pair of side plates 17,17 ', respectively. In order to improve the flexibility of the stop lever 15, a bearing may be disposed between the pin shaft and the hinge hole.

The shaft element supply means may comprise an actuator mounted to the frame 11 or the base 10 and drivingly connected to the stop lever 15 for actuating the rotation of the stop lever 15 in both rotational directions. Or preferably, as shown in fig. 3, the shaft parts supply device does not include a driver, and the rotational axis of the stopper lever 15 is offset from the center of gravity of the stopper lever 15 so that the stopping end 151 of the stopper lever 15 is heavier than the supporting end 152. That is, the hinge portion 153 is disposed at a side deviating from the center of the stopping lever 15 and close to the supporting end 152, so that the stopping end 151 is heavier than the supporting end 152, and the stopping lever 15 is released when the stopping end 151 sinks in a natural state. When the shaft member rolls to the position of the support end 152, the support end 152 is pressed down by the weight of the shaft member, and the stopping end 151 is lifted up, thereby stopping the shaft member which rolls to the position subsequently.

To further protect the stop lever 15 and the shaft member, it is preferable that the stop end 151 of the stop lever 15 is provided with a roller 154 for abutting against the shaft member, as shown in fig. 3, so that the stop end 151 of the stop lever 15 does not generate friction with the surface of the shaft member. Alternatively, the upper surface of the stop lever 15 may be a smooth surface (e.g., a ramp, or an arc) along the extension of the stop lever to further reduce friction and protect the stop mechanism and shaft components.

In order to limit the rotation angle of the stopping lever 15 around the hinge portion 153, preferably, as shown in fig. 3, the bracket 11 may be provided with a limiting member 16 for limiting the rotation range of the stopping lever 15 around the hinge portion 153. The limiting member 16 may be a protrusion or a stopping block or other stopping structure disposed on the rotation path of the supporting end 152 and/or the stopping end 151, so as to limit the rotational degree of freedom of the stopping lever 15 within a certain range, reduce the stroke angle of the stopping lever 15 converted between the stopping state and the releasing state, improve the speed of switching the states of the stopping lever 15, and further improve the working efficiency.

The above-mentioned shaft part supplying means, when no shaft part is supported on the supporting end 152 of the stopping lever 15, the stopping end 151 is in a lower position by gravity, so that the stopping lever 15 is in a released state, allowing the shaft part to roll past the stopping lever 15 supported by the guide rail 12; when the shaft member is supported at the supporting end 152 of the stopping lever 15, the stopping end 151 is rotated to be located at a high position, so that the stopping lever 15 is in a stopping state to stop the other shaft member. Thus, without an actuator, an automatic switching of the stop lever 15 between the stop state and the release state is achieved. According to the shaft part supply device, the stop lever 15 may be plural, and as shown in fig. 4, the plural stop levers are sequentially arranged along the extending direction of the guide rail to stop the plural shaft parts, respectively, so that the shaft part supply device carries and supplies the plural shaft parts in batch and the shaft parts are arranged at intervals.

In order to cooperate with the above-mentioned automatic operation of the stop lever 15, the holder 11 is provided, as shown in fig. 1 and 2, adjacent to the shaft element supply end 14 with a tip 19 for stopping the shaft element. The tip 19 may be a stop structure such as a stop post to stop the shaft element at the shaft element supply end 14, the tip 19 stopping the shaft element at a position where the stopped shaft element just can press against the support end 152 of the stop lever 15 adjacent to the tip 19. The bracket 11 may also be provided with a shaft element receiving mechanism 18 adjacent the shaft element receiving end 13, the shaft element receiving mechanism 18 comprising: a receiving driver 181, the receiving driver 181 being mounted to the stand 11; a pair of receiving arms 182 hinged to the bracket 11 and capable of rotating by the receiving driver 181 to form an inclined surface toward the shaft part receiving end 13. The receiving driver 181 may be a rotary driver, and the rotation of the hinge shaft of the receiving arm 182 is controlled by direct driving or synchronous driving (belt driving, chain driving, etc.). Or preferably, as shown in fig. 2, the receiving actuator 181 is a linear actuator (air cylinder, hydraulic cylinder, electric cylinder, etc.), the hinge shaft of the receiving arm 182 hinged to the bracket 11 is fixedly extended in the radial direction of the shaft to swing the arm, and the receiving actuator 181 controls the receiving arm 182 to swing around the center axis of the hinge shaft by driving the swing of the swing arm. The receiving arm 182 is preferably provided with a bent structure at the end so that the receiving arm 182 can also carry a shaft part when it is lowered, which shaft part rolls from the receiving arm 182 to the guide rail 12 and is in turn stopped by the stop lever 15 when the receiving arm 182 is raised.

The shaft part supply apparatus according to the preferred embodiment of the present application operates as follows: the axle parts are firstly placed on the bending structure at the tail end of the receiving arm 182, the receiving driver 181 drives the receiving arm 182 to swing upwards, and the axle parts roll to the guide rail 12 under the action of gravity. At this time, the plurality of stopper levers 15 are all in the released state, the shaft part rolls along the guide rail 12 until the shaft part supply end 14 is stopped by the tip 19, and the stopper end 151 of the stopper lever 15 adjacent to the tip 19 is lifted. The above-described process is repeated, and the shaft parts are stopped in turn by the stop lever 15 arranged on the bracket 11 in the extending direction of the guide rail 12. At each removal of a shaft element at the shaft element supply end 14, the remaining stopped shaft elements are advanced one position in turn. Thereby realizing batch receiving and supplying of the shaft parts under the condition of mutual isolation between the shaft parts.
