Furthermore, the appearances of the terms first, second, etc. in this specification are not necessarily all referring to the same item, but are instead intended to cover the same item.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The embodiment relates to a car assembly line body workbin retinue device, as shown in fig. 1, it includes on the whole along the slide rail 5 and the line body plate link of the car assembly line body, the head station along with driving 1, the intermediate position along with driving 3 and last station along with driving 4 that set gradually, still include in the head station along with driving 1 and the intermediate position along with between driving 3 to and in the intermediate position along with driving 3 and last station along with driving 4 between the transfer work or material rest 2 that sets up respectively.

In the embodiment, the first station following vehicle 1, the middle station following vehicle 3 and the last station following vehicle 4 are all provided with trays which are positioned on the upper part and used for supporting the material box in a rolling manner and enabling the material box to automatically slide along the traveling direction of the body, caster wheels 6a, 6b, 6c and 6d positioned at the bottom, guide wheels 7 constrained to slide along the sliding rails 5, and a locking mechanism capable of bearing external force to lock or unlock one caster wheel 6 a. And the truckle that is locked by this locking mechanical system is located the line body plate link promptly to can make whole vehicle with following in the motion of line body plate link through this truckle via the drive of line body plate link.

Specifically, as shown in fig. 2 to 8, in the first-station traveling crane 1, the intermediate-station traveling crane 3, and the last-station traveling crane 4 of the present embodiment, the caster, the guide wheel 7, and the locking mechanism provided on each traveling crane are the same. The casters 6a-6d are arranged at four vertex angles at the bottom of the traveling crane, the guide wheels 7 are arranged in the advancing direction along the line body, namely along the sliding track 5 in fig. 1, two pairs of guide wheels 7 are arranged at two ends of the bottom of the traveling crane from the first station along the traveling crane 1 to the last station along the traveling crane 4, and the two guide wheels 7 in each pair of guide wheels 7 are respectively arranged at two opposite sides of the sliding track 5 so as to slide along the sliding track 5 through the guide wheels 7, thereby ensuring that the traveling crane moves along the extending direction of the sliding track 5, namely the line body arrangement mode.

The casters 6a, 6b, 6c, 6d support the entire traveling crane, the casters 6c and 6d close to one side of the guide wheel 7 only play a role of supporting and can roll along with the movement of the traveling crane, and the casters 6a and 6b on the other side are located on the wire body plate chain of the assembly wire body, meanwhile, the casters 6a can be locked by the locking mechanism in the embodiment. Therefore, when the caster 6a is pressed and locked, the caster can not rotate any more, so that the friction force between the caster 6a and the line body plate chain can be utilized, the whole traveling vehicle and the line body plate chain are driven to synchronously move under the guidance of the sliding track 5 through the traveling of the line body plate chain, and the movement synchronous to the line body plate chain is also the traveling vehicle.

After the locking of the caster 6a is released, since it can rotate freely, the traveling vehicle can move relative to the wire body plate chain without traveling with the wire body plate chain if it receives an external pushing and pulling force.

In this embodiment, since the bin needs to enter at the first station traveling crane 1 and leave at the last station traveling crane 4 after the assembly operation is completed, a bin inlet is also provided at one side of the first station traveling crane 1, and a bin outlet is provided at one side of the last station traveling crane 4. In practice, the bin inlet and bin outlet are located on the same side of the leading cart 1 and the trailing cart 4, and are also generally located on one side of the casters 6c, 6d, while one side of the casters 6a, 6b serves as the operator side for the assembler.

In the circulation process of the material box, the material box inlet and the material box outlet can be butted by adopting a lifting mechanism, namely, the lifting mechanism is lifted to enable the material box to slide into the tray of the first station traveling crane 1 from the material box inlet, and the lifting mechanism is lowered at the material box outlet so that the material box on the tray of the last station traveling crane 4 can slide into the lifting mechanism butted at the position through the material box outlet.

The lifting mechanism can be used for referencing the related part in a sliding type line feeding structure in the line feeding of the existing assembly. In this embodiment, the first traveling vehicle 1 and the last traveling vehicle 4 are also used for receiving the entering and leaving of the bin, so that the two trays on the traveling vehicles specifically comprise a plurality of balls 8 arranged along the line body traveling direction. The balls 8 may be arranged in a conventional universal ball structure, for example, as shown in fig. 2 or 4, a plurality of rows of balls 8 are arranged along the traveling direction of the body, and a plurality of balls 8 are arranged at intervals in each row, so that the balls 8 at each position are combined to form a support surface capable of rolling and supporting the bin at the upper parts of the first traveling vehicle 1 and the last traveling vehicle 4.

This embodiment also is provided with the upper table face 16 that is located the tray top respectively on first station along with driving 1, the intermediate position along with driving 3 and last station along with driving 4 to and be located the lower mesa 17 of tray below, two mesas can be used to place relevant article, and for dodging the contact of bearing on the tray, the upper table face 16 of top also sets up to the width less, and only lies in one side along with driving the top. In this case, the above-mentioned bin inlet and bin outlet are also located between the upper deck 16 and the tray for the first position follower 1 and the last position follower 4.

In order to facilitate the feeding of the material box from the material box inlet to the tray of the first station traveling crane 1 and also to facilitate the material box to slide out from the tray of the last station traveling crane 4 through the material box outlet, the material box inlet and the material box outlet are respectively provided with a side guide wheel 9 for guiding the material box to slide into the tray or slide out from the tray. And the side guide wheels 9 are arranged at intervals at the positions of the bin inlet and the bin outlet.

In addition, the bin needs to slide into the tray of the first station along with the travelling crane 1 through the bin inlet, and the bin also needs to be capable of automatically sliding on the tray along the line body advancing direction, and meanwhile, the bin also needs to slide to the bin outlet and further slides out from the bin outlet. Therefore, referring to fig. 6 again, taking the last-station traveling vehicle 4 as an example, the whole tray formed by the balls 8 is declined along the traveling direction of the line body (the direction from right to left in fig. 6), and the automatic sliding of the work bin on the tray can be realized by the declination under the action of the self weight and the counter weight of the work bin.

Meanwhile, in the direction orthogonal to the line body traveling direction, as shown in fig. 3, the entire tray of the first station traveling crane 1 is tilted upward in the entering direction of the bin (the direction from right to left in fig. 3), and as shown in fig. 5, the entire tray of the last station traveling crane 4 is tilted upward in the sliding-out direction of the bin (the direction from left to right in fig. 5). At this moment, the first station inclines upwards along the material box entering direction along with the tray in the traveling crane 1, and the last station inclines upwards along the material box sliding-out direction along with the tray in the traveling crane 4, so that the material box can smoothly flow into the first station along with the traveling crane 1 from the first station lifting mechanism, and the material box smoothly flows out to the last station lifting mechanism from the last station along with the traveling crane 4.

Unlike the pallets at the first station traveling crane 1 and the last station traveling crane 4, the pallet on the middle station traveling crane 3 of the present embodiment is shown in fig. 7, and includes a plurality of raceways 18 arranged side by side in the line body traveling direction, and as shown in fig. 8, each raceway 18 is also tilted downward in the line body traveling direction, so as to realize the automatic sliding of the bin as well.

In this embodiment, the end guide wheels 10 for guiding the bin to slide out of or into the tray from the tray are respectively arranged at the tail end of the first station traveling vehicle 1 and the head end of the last station traveling vehicle 4 along the line body traveling direction, so that the bin enters the transfer rack 2 adjacent to the first station traveling vehicle 1 from the first station traveling vehicle 1, and the bin enters the last station traveling vehicle 4 from the transfer rack 2 adjacent to the last station traveling vehicle 4 from the last station traveling vehicle 4. The end guide wheels 10 on each pallet can be arranged in a plurality at intervals like the side guide wheels 9, and structurally, the end guide wheels 10 of each side guide wheel 9 can adopt the same structure, so as to facilitate universal replacement.

In addition, because the workbin can slide on each tray automatically, in order to avoid the workbin to slide to first station along with driving 1, intermediate position along with driving 3 and each transfer work or material rest 2 terminal when dropping, this embodiment is along the same body advancing direction along the line, is provided with the activity that can block the workbin that slides automatically and stops 11 respectively at first station along with driving 1, intermediate position along with driving 3 and two transfer work or material rest 2's terminal.

Correspondingly, the head ends of the intermediate station follow-up crane 3, the last station follow-up crane 4 and each transfer rack 2 are also respectively provided with a push rod 15 which can push the corresponding movable barrier 11, so that the pushed movable barrier 11 is turned over to cancel the barrier. And the tail end of the tail station traveling trolley 4 can block the material box through the self support structure of the traveling trolley, and a movable block 11 is not required to be arranged.

The above reversible arrangement of the movable block 11 is combined with that shown in fig. 11, which is a natural state, the movable block 11 makes the abutting rod 113 and the cross beam in an interference state under the action of the counterweight 114, so that the stop rod 112 connected with the abutting rod 113 is in a vertical state, and the stop function is realized by the stop rod 112. During butt joint, the ejector rod 15 pushes the nylon tube 111, so that the nylon tube 111 and the connecting tube located in the nylon tube 111 rotate anticlockwise, the stop lever 112 moves anticlockwise, the stop lever 112 is in an open state at the moment, the opening function of the movable stop 11 is realized, and the material box flows out.

The locking ejector rod 12 is connected with the locking rod 122, the locking piece 121 is arranged on the locking ejector rod 122, the limiting piece 123a is arranged on the limiting rod 123, and the reset spring is arranged on at least one of the unlocking ejector rod 13, the limiting rod 123, the locking rod 122 and the locking ejector rod 12. And because of receiving external touch force, the locking piece 121 slides along with the locking ejector rod 12 and can be limited by the limiting piece 123a, so that the caster 6a is locked by the locking rod 122, or the unlocking ejector rod 13 can drive the limiting rod 123 to swing, so that the limiting of the locking piece 121 is released, and the locking rod 122 is driven by the reset spring to release the locking.

In detail, the locking ejector rod 12, the unlocking ejector rod 13 and the locking rod 122 are slidably disposed through a plurality of tubular mounting structures arranged at intervals, and the locking member 121 may generally be a bearing-like member disposed on the locking ejector rod 12 so as to facilitate crossing over the limiting member 123 a. In the present embodiment, as a preferred embodiment, a locking rubber wheel 124 protruding outward from one side is also disposed at one end of the locking rod 122, and when locking is performed, that is, the locking rubber wheel 124 slides to the caster 6a along with the locking rod 122, and the locking rubber wheel 124 presses and locks the caster 6 a.

In the present embodiment, the unlocking mandril 13 is sleeved with the unlocking mandril reset spring 132, the locking mandril 12 and the locking rod 122 are specifically sleeved with the locking rod reset spring 125, and the locking rod 122 and the locking mandril 12 are connected together, so the locking rod reset spring 125 is also used for synchronous sliding reset of the locking rod 12 and the locking mandril 12.

With reference to fig. 12 as an orientation reference, the left end of the limiting rod 123 of the present embodiment is pivotally connected to the main frame of the following vehicle, and the return spring disposed at the limiting rod 123 is a torsion spring, which is specifically used for returning the limiting rod 123 after swinging. In addition, the limiting member 123a disposed on the limiting rod 123 is a right triangle structure, and one side of the hypotenuse faces one side of the locking member 121 in the unlocked state, so that when the locking member 121 slides along with the locking top rod 12 and enters the inner side of the limiting member 123a, i.e., one side of the right-angle side, the locking member 123a can be stopped and limited, and the locking top rod 12 and the locking rod 122 are positioned in the locked state, in which the locking rubber wheel 124 compresses the caster 6 a.

As for the unlocking top rod 13 driving the swing of the limiting rod 123, the embodiment is a preferred embodiment, specifically, an unlocking pulley 131 is disposed at the end of the unlocking top rod 13, and an unlocking piece 123b is further disposed on the limiting rod 123 at an interval from the limiting piece 123a, the unlocking piece 123b is also in a right triangle shape, and one side of the oblique side of the unlocking piece is disposed corresponding to the unlocking pulley 131, so that as the unlocking top rod 13 slides to one side of the unlocking piece 123b, the unlocking pulley 131 can press the unlocking piece 123b, and the limiting rod 123 can be driven to swing.

When the locking mechanism of this embodiment specifically works, as shown in fig. 12 again, when the locking ejector rod 12 is touched, the locking piece 121 mounted on the locking ejector rod 12 abuts against the limiting piece 123a, so that the limiting rod 123 swings, after the locking piece 121 crosses the limiting piece 123a, the limiting rod 123 returns to the position, so that the locking piece 121 is limited at the inner side of the limiting piece 123a, the locking rod return spring 125 is compressed, and the locking ejector rod 12 and the locking rod 122 are positioned at the locking position, and the locking is realized by the locking rubber wheel 124.

When the unlocking ejector rod 13 is touched, the unlocking ejector rod 13 slides and compresses the unlocking ejector rod return spring 132, the unlocking pulley 132 on the unlocking ejector rod 13 pushes the unlocking piece 123b to drive the limiting rod 123 to swing to release the limiting on the locking piece 121, the locking rod 122 and the locking ejector rod 12 slide reversely under the action of the locking rod return spring 125, the locking rubber wheel 124 releases the pressing and locking of the caster 6a, so that unlocking is realized, and the unlocking ejector rod 13 returns under the action of the unlocking ejector rod return spring 132 after unlocking. In this way, the respective operations of the locking jack 12 and the unlocking jack 13 can be achieved, and the desired locking and unlocking effects can be achieved by the locking lever 122.

Wherein, above-mentioned line body fixing device sets up in transfer work or material rest 2 bottoms.

After the caster 6a is locked, the traveling vehicle can follow the line body plate chain, and when the material box enters the transfer material frame 2 or slides out from the outlet of the material box, and is in butt joint with the transfer material frame 2, the unlocking ejector rod 13 can be touched by a stop lever at the bottom of the transfer material frame 2, so that the unlocking ejector rod 13 can slide, and finally, the locking rod 122 is driven to slide reversely, and the compression on the caster 6a is removed, so that the locking is removed. And the bottom stop lever is arranged at the bottom of the transfer rack 2 corresponding to the unlocking ejector rod 13.

In addition, in order to temporarily unlock the vehicle in the traveling process, the locking mechanism of the embodiment further includes a temporary manual unlocking handle 14 disposed on one side of the unlocking push rod 13, and the temporary manual unlocking handle 14 is slidably inserted into the limiting rod 123 and is connected to the limiting rod 123 through an unlocking pull wire 142, so as to drive the limiting rod 123 to swing. Meanwhile, a return spring 141 is also provided at the temporary manual unlock handle 14.

Therefore, when the following needs to be temporarily released, the temporary manual unlocking handle 14 is pressed, and the limiting rod 123 can swing as driven by the unlocking ejector rod 13 through the driving of the unlocking pull wire 142, so that the limitation on the locking piece 121 is released, the locking rod 122 and the locking ejector rod 12 slide and return, and the locking rubber wheel 124 releases the compression on the caster 6 a. When the temporary manual unlocking handle 14 is not pressed, the temporary manual unlocking handle 14 can return to the original position for the next use under the returning action of the return spring 141 and the returning swing of the limiting rod 123.

As shown in fig. 9 and 10, the present embodiment is provided with a slide rail at the upper portion of the transfer frame 2 to roll and support the bin and also to enable the bin to automatically slide along the traveling direction of the body. The two sets of slide ways are also arranged in sequence along the line advancing direction, wherein for convenience of description, the two sets of slide ways arranged in sequence along the line advancing direction, that is, the material box advancing direction, are respectively called an upstream slide way 19 and a downstream slide way 20, and the upstream slide way 19 located at the upstream in the embodiment is also arranged in a liftable manner, and a driving part for driving the upstream slide way 19 to ascend and descend is arranged in the transfer rack 2.

In particular, each slideway can adopt the same structure as the raceway 18 in the intermediate station traveling crane 3. The upstream slide 19 may be mounted on a sliding bracket 21, and a pulley may be disposed at an end of the sliding bracket 21 to guide the upstream slide 19 carried by the sliding bracket to move up and down smoothly. In addition, the driving part can adopt an air cylinder 22, the air cylinder rod of the driving part can be connected with the sliding bracket 21, and in order to realize effective control on the action of the air cylinder 22, the embodiment is also provided with a switch unit which can receive the pressing of the bin sliding to the position and be triggered so as to enable the air cylinder 22 to act.

The switch unit can adopt a linkage rod 24 which is arranged on the transfer rack 2 in a turnover mode, and a roller 25 is arranged at one end of the linkage rod 24 so as to bear the pressing of the bin and reduce the friction with the bin support. The other end of the linkage rod 24 can be connected with a control switch part of the cylinder 22, and an elastic part such as a torsion spring for driving the pressed linkage rod 24 to return is arranged between the linkage rod 24 and the transfer rack 2. Thus, when one end of the linkage rod 24 having the roller 25 is pressed by the bin to turn over, the other end of the linkage rod triggers the control switch to operate, so as to control the cylinder 22 to extend to lift the upstream chute 19.

When the upstream slide way 19 is lifted to be higher than the downstream slide way 20, the bin can automatically slide to the downstream slide way 20 because the upstream slide way 19 and the downstream slide way 20 are both declined along the line body travelling direction. At this point, the linkage 24 is released from the compression of the magazine and can be reset, thereby giving the control switch another way of triggering, so that the cylinder 22 is controlled to retract.

In this embodiment, in order to further ensure the stability of the ascending and descending movement of the upstream chute 19, a counterweight 23 connected to the upstream chute 19 through a counterweight pull wire 231 is further disposed on the middle material transferring frame 2.
