Detailed Description

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

The application provides a rotatory transfer machine, wherein, rotatory transfer machine is including being used for carrying the transport portion 100 of material, the rotation portion 200 that is used for rotatory material direction and being used for the direction transport portion 100 carries the guiding portion 300 of material, transport portion 100 includes two parallel arrangement's conveying mechanism 110, rotation portion 200 includes can two the rotatory revolving stage 210 of lift between conveying mechanism 110, guiding portion 300 is including setting up at every at least one adjustable guide 310 in the conveying mechanism 110 outside and setting up fixed guide 320 in the adjustable guide 310 outside, adjustable guide 310 sets up to can be in the direction position of direction material and be less than the position of dodging of direction position between adjustment position.

Using the rotary transfer machine of the present application, materials can be conveyed to the rotary part 200 through the conveying part 100, then lifted and rotated through the rotary part 200 to change the direction of the materials, and then the rotary part 200 is lowered, so that the adjustable guide 310 which is not matched with the current material positioning is located at the avoiding position, and guided by the adjustable guide 310 or the fixed guide 320 which is matched with the previous material positioning, and then can be continuously sent out through the conveying part 100.

Specifically, the adjustable guide 310 and the fixed guide 320 are each provided in pairs and the distances between the pairs of guides are different. Taking the illustrated example with a pair of adjustable guides 310, the distance between the pair of adjustable guides 310 is smaller than the distance between the pair of fixed guides 320, when the material is positioned such that the dimension of the material perpendicular (transverse) to the conveying direction is smaller, as shown in fig. 3, the conveying of the material can be guided by the pair of adjustable guides 310; when the material is changed in position so that the size of the material perpendicular (transverse) to the conveying direction is large, as shown in fig. 2, it is possible to raise and rotate the rotating part 200 to descend after the change in position and to place the adjustable guide 310 at the avoidance position, so that the conveying of the material can be guided by the pair of fixed guides 320. It will be appreciated that with more adjustable guides 310, more dimensions of the material may be accommodated to guide the transport of the material as it is positioned at different angles and with different dimensions perpendicular (transverse) to the transport direction.

The adjustable guide 310 may be adapted to effect its positional adjustment in a suitable manner. Preferably, the adjustable guide 310 can be made to support the material after it falls, so as to switch it from the guiding position to the avoiding position by the action of the weight of the material. For example, the adjustable guide 310 may be supported by an elastic element to force the spring to deform under the force of gravity of the material to switch positions.

Preferably, in order to make the switching smoother, as shown in fig. 7, the guide 300 may include a first bracket 330, a rotating member 340 rotatably installed to the first bracket 330, and an elastic member 350 installed to the first bracket 330, one end of the adjustable guide 310 being connected to the rotating member 340 to be able to descend to the escape position with the rotation of the rotating member 340 by the gravity of the material, the elastic member 350 being connected to the adjustable guide 310 to be able to restrict the descent of the adjustable guide 310.

Thus, when the material is repositioned such that its dimension perpendicular (transverse) to the direction of conveyance is greater than the spacing between the pair of adjustable guides 310, the material will press against the pair of adjustable guides 310 as it falls, and the adjustable guides 310 will descend to the stowed position as the rotary member 340 rotates against the spring force of the resilient member 350, as shown in fig. 9. When material is conveyed off the rotary transfer machine, the elastic force of the elastic member 350 forces the adjustable guide 310 back to the guiding position, as shown in fig. 8.

Wherein, by providing the rotation member 340, the position switching of the adjustable guide 310 can be made smoother. The rotary member 340 may take a suitable form, for example, may be a bearing.

Wherein preferably the resilient member 350 is disposed proximate the other end of the adjustable guide 310 to exert sufficient torque through the resilient member 350 to return to the guiding position. It will be appreciated that as shown in fig. 8 and 9, the adjustable guide 310 is gradually raised in the conveying direction in the guiding position, and the adjustable guide 310 is substantially parallel to the conveying direction in the avoiding position, and the mounting structure of the elastic member 350 may be correspondingly configured to accommodate the position switching of the adjustable guide 310. For example, the mounting base 360 may be fixed to the first bracket 330, the mounting base 360 is provided with a long groove 361, one end of the elastic member 350 is fixed to the mounting base 360, and the other end is connected to the adjustable guide member 310 through the long groove 361, so that the elastic member 350 can move in the long groove 361 to adapt to the position switching of the adjustable guide member 310 when the position is switched.

It will be appreciated that where there are multiple pairs of adjustable guides 310, the corresponding rotary members 340 of each adjustable guide 310 may be spaced apart in the conveying direction so as not to interfere. The first bracket 330 may be provided with corresponding mounting structures to mount each of the rotary members 340. The fixing guide 320 may be attached to the first bracket 330.

Wherein the adjustable guide 310 and the fixed guide 320 may be elongated members disposed in a conveying direction so as to guide the conveyance of the material through the inner side surfaces of the members. To provide a secure guide, the adjustable guide 310 and the fixed guide 320 may have a suitable strength, for example, may be metal pieces. To avoid damage to the adjustable guide 310 caused by direct contact of the top surface with material in the retracted position, the top of the adjustable guide 310 may be provided with a flexible support 311 for supporting the material in the retracted position. The guide surface of the fixed guide 320 may be provided with a wear plate 370.

In the present application, it is preferable to attach the guide 300 between the conveying mechanisms 110 in an embedded manner in order to simplify the structure and reduce the occupied space. Specifically, as shown in fig. 4, the conveying part 100 may include a second bracket 120 for mounting the conveying mechanism 110, and the second bracket 120 may have a width greater than that of the first bracket 330 so that the guide part 300 may be disposed between the conveying mechanisms 110 in an embedded manner.

The conveying mechanism 110 may be a chain conveying mechanism and include a chain conveying assembly 111, and the conveying portion 100 may further include a driving mechanism 130 for driving the chain conveying assembly 111. The driving mechanism 130 may be disposed between the two conveying mechanisms 110 to simultaneously drive the two conveying mechanisms 110. The driving mechanism 130 may also be mounted to the second bracket 120.

In this application, the rotating part 200 may take a proper form to lift and rotate the material. Preferably, as shown in fig. 5, the rotating unit 200 includes a jacking mechanism 220, and the rotating table 210 is mounted on the jacking mechanism 220. The lifting mechanism 220 may take a suitable form, and may be, for example, a hydraulic lifting device.

To further save space, the rotating portion 200 may be provided inside the guide portion 300 in an embedded manner. Specifically, the width of the first bracket 330 is greater than the width of the lifting mechanism 220, so that the rotating part 200 can be disposed inside the guide part 300 in an embedded manner. Thus, as shown in fig. 1, the rotary transfer machine can have a compact structure in which the conveying unit 100, the guide unit 300, and the rotary unit 200 are nested in this order. Also, the first and

second brackets

330 and 120 may be separate brackets so that the conveying part 100, the guide part 300, and the rotating part 200 are separately moved, assembled, and integrally debugged.

The rotary table 210 may take any suitable form for rotating the material. For example, in the embodiment shown in fig. 5, the rotary table 210 may include a pivoting support 211 mounted to the jacking mechanism 220, a rotating top plate 212 mounted to the pivoting support 211, and a driving unit 213 for driving the pivoting support 211. A cover plate 214 may be disposed on the rotating top plate 212 to cover the slewing bearing 211, the driving unit 213, and the like, and in use, the cover plate 214 contacts the load-bearing material and protects the internal components.

The driving unit 213 may take a suitable form, for example, as shown in fig. 6, the driving unit 213 may include a motor 2131, a rotation shaft 2132 connected to an output shaft of the motor 2131, a gear 2133 coaxially fixed to the rotation shaft 2132, and a gear ring 2134 engaged with the gear 2133, an inner surface of the gear ring 2134 having teeth engaged with the gear 2133, the gear ring 2134 being connected to the slewing bearing 211. The motor 2131 drives the rotation shaft 2132 and the gear 2133 to rotate, which in turn drives the ring gear 2134 and the slewing bearing 211 to rotate, so that the cover 214 carries the material to rotate.

To facilitate control of the change of the orientation of the material, the rotating part 200 may include a control unit for controlling the driving unit 213 and a monitoring unit for monitoring the rotation angle of the rotary table 210, the control unit being electrically connected to the monitoring unit to control the operation of the driving unit 213 according to feedback of the monitoring unit. Specifically, when the monitoring unit monitors that the rotary table 210 rotates to a predetermined angle, a signal is fed back to the control unit, and the control unit can control the rotary table 210 to stop rotating according to the signal, so that the material rotates to a predetermined direction.

According to the shape and conveying requirement of the materials, the corresponding rotation direction can be set so as to enable the materials to achieve the required positioning. Accordingly, the rotation angle monitored by the monitoring unit can be set. For this purpose, the monitoring unit is configured to be able to monitor at least the rotation of the rotary table 210 by 90 ° and 180 °. Thus, at least the materials with different sizes in the vertical direction can be subjected to steering monitoring. For example, in the embodiment shown in fig. 5, the monitoring unit may include a first monitoring element 240 and a second monitoring element 250 (e.g., proximity switches), the first monitoring element 240 and the second monitoring element 250 may be disposed around the rotation table 210 at intervals of 90 °, and a flag capable of being monitored by the first monitoring element 240 and the second monitoring element 250 may be disposed on the rotation table 210 so as to be recognized by the first monitoring element 240 and the second monitoring element 250 when the flag is rotated to correspond to the first monitoring element 240 and the second monitoring element 250, thereby detecting that the rotation table 210 is rotated by 90 ° and 180 °.

In addition, the operation of the jacking mechanism 220 may be monitored to control the lifting of the rotary table 210. Specifically, the jacking mechanism 220 and the first bracket 330 (or the second bracket 120) may be provided with a first height detecting element 230 and a second height detecting element 380 corresponding to each other to monitor the lifting process by lifting the jacking mechanism 220 to bring the first height detecting element 230 and the second height detecting element 380 to corresponding positions. The first and second

height detection elements

230, 380 may take a suitable form (e.g., proximity switch) and may be electrically connected to the control unit such that the control unit controls the jacking mechanism 220 in accordance with the detection of the first and second

height detection elements

230, 380.

In addition, the first bracket 330 may further be provided with a limit detection element 390 connected with the alarm unit, so as to limit the maximum travel of the lifting mechanism 220, when the lifting of the lifting mechanism 220 reaches the limit detection element 390, the limit detection element 390 may feed back to the alarm unit, and the alarm unit immediately alarms.

The first bracket 330 may include a mounting frame 331 for mounting the adjustable guide 310 and the fixed guide 320 and a cross member 332 connected between the mounting frames 331, and the second height detecting element 380 and the limit detecting element 390 may be disposed on the cross member 332 so as to correspond to the related components of the detecting rotation part 200 in the middle of the cross member 332.

It can be appreciated that the material direction can be changed by the rotating portion 200 after the material enters the conveying portion 100, so that the rotating portion 200 can be disposed at the input end of the rotary transfer machine along the conveying direction, thereby reducing the size of the conveying direction. For this purpose, correspondingly sized conveying sections 100 and guide sections 300 can be provided. Alternatively, the existing longer delivery distance delivery section 100 may be utilized, but without lengthening the guide 300 to accommodate. As shown in fig. 1, the rotating part 200 may be provided at a middle part of the rotary transfer machine in the conveying direction, and an auxiliary guide part 400 may be provided at one end of the conveying part 100 having a long conveying distance, and the guide part 300 may extend from the middle part to the other end of the conveying part 100, so that the material is guided in the conveying direction by the auxiliary guide part 400 together with the guide part 300. The auxiliary guide 400 is only used for auxiliary guide, and may be used as, for example, a rough guide when the material enters or leaves the rotary transfer machine, and thus, the distance between the pair of auxiliary guide 400 may be the same as the distance between the fixed guides 320.

The operation of the rotary transfer machine of the present application is described below with reference to the drawings.

In the illustrated embodiment, the material is represented by a tray 500, and the tray 500 has a rectangular parallelepiped shape.

When the tray 500 needs to be changed from being conveyed in the length direction thereof (as shown in fig. 2) to being conveyed in the width direction thereof (as shown in fig. 3), the following operations are performed:

first, the tray 500 is conveyed from one end of the rotary transfer machine to the middle by the conveying section 100, and in this process, the conveying direction of the conveying section 100 coincides with the longitudinal direction of the tray 500, and both sides of the tray 500 are guided by the adjustable guides 310, as shown in fig. 8.

When the tray 500 is transferred to the rotating part 200, the rotation table 210 is lifted up by the lifting mechanism 220 so that the rotation table 210 holds the tray 500 up to above the adjustable guide 310, and then can be rotated by 90 ° by the rotation table 210 to change the direction of the material.

Subsequently, the rotation table 210 and the tray 500 are lowered by the jacking mechanism 220 so that the tray 500 is supported on the conveying part 100 and the adjustable guide 310 is pressed down to the avoidance position.

Finally, the tray 500 is continuously conveyed by the conveying section 100 such that both sides of the tray 500 are guided by the fixed guides 320 until leaving the rotary transfer machine.

When the tray 500 needs to be changed from being conveyed in the length direction thereof (as shown in fig. 3) to being conveyed in the width direction thereof (as shown in fig. 2), the following operations are performed:

first, the tray 500 is conveyed from one end of the rotary transfer machine to the middle by the conveying section 100, in which process the conveying direction of the conveying section 100 coincides with the width direction of the tray 500, both sides of the tray 500 are guided by the fixed guides 320 and the tray 500 always presses the adjustable guides 310 to be located at the avoidance position, as shown in fig. 9.

When the tray 500 is transferred to the rotating part 200, the rotation table 210 is lifted up by the lifting mechanism 220, so that the rotation table 210 holds the tray 500 up to be separated from the adjustable guide 310, and the adjustable guide 310 is restored to the guide position by the elastic member 350. And then rotated 90 deg. by the rotary table 210 to change the direction of the material.

Subsequently, the rotation table 210 and the tray 500 are lowered by the lift mechanism 220 so that the tray 500 is supported on the conveying section 100.

Finally, the tray 500 continues to be conveyed by the conveying section 100 such that both sides of the tray 500 are guided by the adjustable guides 310 until exiting the rotary transfer machine.

Compared with the existing situation that conveying mechanisms are arranged at different heights and lifting mechanisms are arranged at the connecting positions, the rotary transfer machine provided by the application only needs to convey the conveying parts 100 in one direction, and does not need to occupy conveying space at different heights, so that equipment cost, power and occupied space can be reduced, and the rotary transfer machine can be more compact and lower in height. In addition, the rotary transfer machine can be arranged at any position according to the requirement, and is convenient to flexibly use under the condition of changing the conveying route according to the requirement.

In addition, the specific features described in the foregoing embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, various possible combinations are not described in detail.

Moreover, any combination of the various embodiments of the present application may be made without departing from the spirit of the present application, which should also be considered as disclosed herein.
