Example one

Fig. 4 is a top view of the dispenser according to the present embodiment. As shown in fig. 4, the dispenser includes a swing arm mechanism 100 and a clamp arm mechanism 500.

The swing arm mechanism 100 comprises a first swing arm assembly 120 and a second swing arm assembly 130, wherein the first swing arm assembly 120 and the second swing arm assembly 130 which are symmetrically arranged form a channel 110 for the articles to enter and exit, and the channel 110 is provided with an inlet 112 and an outlet 112. The first and second

swing arm assemblies

120 and 130 swing such that the inlet 112 and the outlet 111 expand or contract, and the states of expansion and contraction of the inlet 112 and the outlet 111 are reversed.

The clamp arm mechanism 500 includes a first clamp arm assembly 510 and a second clamp arm assembly 520. The first clamping arm assembly 510 and the second clamping arm assembly 520 are respectively disposed at the ends of the first swing arm assembly 120 and the second swing arm assembly 130 corresponding to the inlet 112. The first and second

clamp arm assemblies

510 and 520 extend outwardly in a direction away from the channel 110 to clamp an article.

Specifically, as shown in fig. 4, the article is a tire or other articles, which is not limited in this embodiment. The channel 110 is enclosed by a first swing arm assembly 120 and a second swing arm assembly 130. When the first swing arm assembly 120 and the second swing arm assembly 130 swing, the first swing arm assembly 120 and the second swing arm assembly 130 move away from or towards the corresponding inlet 112 end or outlet 111 end, so that the inlet 112 or outlet 111 of the channel 110 expands or contracts, and the contracted and expanded states of the outlet 111 are opposite to the contracted and expanded states of the inlet 112. This allows passage 110 to accommodate the entry and exit of a tire, which enters passage 110 through inlet 112 and exits through outlet 111.

Further, with reference to fig. 4, the first swing arm assembly 120 includes a first front arm 121 and a first rear arm 123, one end of the first front arm 121 and one end of the first rear arm 123 are fixedly connected, and the other end of the first front arm 121 and the other end of the first rear arm 123 respectively correspond to the inlet 112 and the outlet 111. The first clamp arm assembly 510 is disposed at an end of the rear arm 123 corresponding to the inlet 112 and extends outwardly in a direction away from the channel 110. The planar shapes of the first front arm 121, the first rear arm 123 and the first clamping arm assembly 510 are zigzag.

The second swing arm assembly 130 includes a second front arm 131 and a second rear arm 133, one end of the second front arm 131 and one end of the second rear arm 133 are fixedly connected, and the other end of the second front arm 131 and the other end of the second rear arm 133 respectively correspond to the inlet 112 and the outlet 111. The second clamping arm assembly 520 is disposed at an end of the second rear arm 133 corresponding to the inlet 112 and extends outwardly in a direction away from the channel 110. The planar shapes of the second front arm 131, the second rear arm 133 and the second clamping arm assembly 520 are zigzag.

In detail, the first front arm 121 and the second front arm 131 are located on the outlet 111 side, and the first rear arm 123 and the second rear arm 133 are located on the inlet 112 side. The first front arm 121 and the first rear arm 123 are arranged in a V shape, and the second front arm 131 and the second rear arm 133 are arranged in a V shape. In this manner, a tire-receiving passageway 110 can be formed between the first and second

swing arm assemblies

120, 130.

Further, the inner included angle of the V-shaped structure is an obtuse angle. Although it is also possible to form a channel 110 for accommodating a tire between the first swing arm assembly 120 and the second swing arm assembly 130 when the included angle of the V-shape is a right angle or an acute angle, the first swing arm assembly 120 and the second swing arm assembly 130 need to be enlarged to allow the space of the channel 110 to sufficiently accommodate a tire when the included angle of the V-shape is a right angle or an acute angle, which may cause the first swing arm assembly 120 and the second swing arm assembly 130 to be heavy.

Alternatively, the V-shape may be a U-shape, or a simple variation of the V-shape, such that a channel 110 for receiving a tire is formed between the first swing arm assembly 120 and the second swing arm assembly 130.

A first rotating point 122 is arranged at the fixed connection position of the first front arm 121 and the first rear arm 123, and the first swing arm assembly 120 swings around the first rotating point 122. A second rotation point 132 is arranged at the fixed connection position of the second front arm 131 and the second rear arm 133, and the second swing arm assembly 130 swings around the second rotation point 132.

Further, the lengths of the first front arm 121, the second front arm 131, the first rear arm 123 and the second rear arm 133 are all the same. In this way, when the swing arm mechanism 100 swings, the opening size when the outlet 111 expands and the opening size when the inlet 112 expands coincide, and the opening size when the outlet 111 contracts and the opening size when the inlet 112 contracts coincide.

Preferably, the first clamping arm assembly 510 and the second clamping arm assembly 520 are linear rods. When contracted at inlet 112, first gripper arm assembly 510 and second gripper arm assembly 520 are angled. Thus, the range of the tires captured by the first clamping arm assembly 510 and the second clamping arm assembly 520 is increased, the tires can be further prevented from sliding to the edge of the conveying line, the probability of the tires entering the inlet 112 is increased, and the tires can be prevented by the swing arm mechanism 100. It should be understood that the size of the included angle is determined empirically by those skilled in the art, and this embodiment is not limited thereto.

Fig. 6 is a schematic diagram of a swing arm mechanism 500 of the single player provided in the present embodiment.

As an alternative embodiment, as shown in fig. 6, the first and second

clamping arm assemblies

510 and 520 may be in a parallel state when the inlet 112 is contracted. First rear arm 123, second rear arm 133, first gripper arm assembly 510, and second gripper arm assembly 520 form an M-shaped opening. When a tire enters the inlet 112, the first rear arm 123 and the second rear arm 133 block the tire, and the first clamping arm assembly 510 and the second clamping arm assembly 520 clamp the tire. Even if the transfer rollers on the conveyor line always apply a forward force to the tire, it cannot cause the tire to disengage from the entrance 112.

Fig. 7 is a schematic diagram of another swing arm mechanism 500 of the single player provided in the embodiment.

As an alternative embodiment, as shown in fig. 7, first clamp arm assembly 510 and second clamp arm assembly 520 are each an arcuate bar. The contact surface of arc pole and tire is the cambered surface, and the tire can be with rolling mode entering entry 112, produced frictional force when having reduced tire and first arm lock subassembly 510 or second arm lock subassembly 520 extrusion, can reduce the probability that the tire surface produced the mar, ensures the quality of tire.

Optionally, with continued reference to fig. 4, the first front arm 121 and the second front arm 131 correspond to the end of the outlet 111, and the first rear arm 123 and the second rear arm 133 correspond to the end of the inlet 112, and are provided with rollers to prevent the ends from directly contacting with the tire, which may result in the tire being scratched.

Further, a plurality of rollers are disposed on the first clamping arm assembly 510 and the second clamping arm assembly 520, and the rollers are disposed on one side of the first clamping arm assembly 510 and the second clamping arm assembly 520 close to the channel 110.

Specifically, due to the existence of the first clamping arm assembly 510 and the second clamping arm assembly 520, when a tire is not on the center line of the conveying line, the tire is firstly contacted with the first clamping arm assembly 510 or the second clamping arm assembly 520 before entering the inlet 112, and the tire is pressed by the first clamping arm assembly 510 or the second clamping arm assembly 520, so that a force for correcting the motion track is generated. The friction force generated by the tire pressing against the first clamping arm assembly 510 or the second clamping arm assembly 520 may cause scratches on the surface of the tire, which may result in the quality of the tire being degraded, or even cause the tire to be unqualified. Therefore, a plurality of rollers are disposed on the first gripper arm assembly 510 and the second gripper arm assembly 520, and when the tire trajectory is corrected by the first gripper arm assembly 510 or the second gripper arm assembly 520, the tire contacts the rollers on the first gripper arm assembly 510 or the second gripper arm assembly 520. After the tire contacts with the roller, the roller rotates, and the friction force between the surface of the tire and the roller can be reduced.

Further, the gyro wheel preferably nylon gyro wheel, nylon gyro wheel texture is soft, when tire and gyro wheel extrusion, has the surplus of buffering, can further reduce the probability that the tire surface produced the mar, ensures the quality of product.

Optionally, the material of the first clamping arm assembly 510 and the second clamping arm assembly 520 is Q235B carbon steel.

In particular, the Q235B carbon steel has certain elongation and strength, good toughness and castability, is easy to punch and weld, and is widely used for manufacturing general mechanical parts. First clamping arm assembly 510 and second clamping arm assembly 520 are made of Q235B carbon steel, so that first clamping arm assembly 510 and second clamping arm assembly 520 have better yield strength, deformation of first clamping arm assembly 510 and second clamping arm assembly 520 in use is avoided, and the service life of the dispenser is ensured.

The cylinder is good at reciprocating linear motion and is especially suitable for the most transmission requirements in industrial automation. Further, the air cylinder is applied to this embodiment, and can effectively absorb the kinetic energy generated when the tire collides against the swing arm mechanism 100. In the application scenario of the embodiment, the impact is required to be continuously received, and the service life is longer. Moreover, the air cylinder absorbs the kinetic energy generated when the tire impacts the swing arm mechanism 100, so that the mechanical load of other components in the single player, such as the crank rocker mechanism 200, can be effectively reduced, and the service life of the single player is further prolonged.

The single player is disposed on a conveying line, and when the single player works, the driving mechanism 300 drives the crank-rocker mechanism 200, and the crank-rocker mechanism 200 drives the first bearing shaft 412 and the second bearing shaft 422 to rotate or revolve.

As shown in fig. 4, when the crank-rocker mechanism 200 drives the first bearing shaft 412 and the second bearing shaft 422 to rotate, the outlet 111 of the swing arm mechanism 100 is contracted, and simultaneously, the inlet 112 is expanded. The tire enters the channel 110 from the inlet 112 of the swing arm mechanism 100, and the first and second

front arms

121 and 131 clamp the tire so that the tire stays at the outlet 111 within the channel 110.

Fig. 8 is a schematic structural diagram of the single dispenser provided in the present embodiment when releasing the tire.

As shown in fig. 8, when the crank-rocker mechanism 200 drives the first bearing shaft 412 and the second bearing shaft 422 to rotate, the outlet 111 of the swing arm mechanism 100 is expanded, and the inlet 112 is contracted. The tire in the passage 110 is delivered from the outlet 111. The tire passing from the conveyor line is stopped by the first rear arm 123 and the second rear arm 133 at the inlet 112.

Even if the tire is not on the center line of the conveying line, the first swing arm assembly 120 and the second swing arm assembly 130 are provided with the first clamping arm assembly 510 and the second clamping arm assembly 520, so that the running track of the tire can be automatically corrected under the action of the first clamping arm assembly 510 or the second clamping arm assembly 520. In this manner, the tire may enter the inlet 112 of the swing arm mechanism 100. The first rear arm 123 and the second rear arm 133 block the tire at the inlet 112, and the first gripper arm assembly 510 and the second gripper arm assembly 520 grip the tire without causing the tire to disengage from the inlet 112 of the swing arm mechanism 100 even if the rollers on the conveyor line always apply a forward force to the tire. The probability of the tire entering the channel 110 is increased, and the accuracy of tire single placement is ensured.

Optionally, the singler is disposed on an inclined conveyor line that is inclined such that the inlet 112 is higher than the outlet 111. In this way, when the tire is transferred into or out of the channel 110 of the swing arm mechanism 100, because the height of the inlet 112 is greater than that of the outlet 111, when the tire is conveyed in the channel 110, a greater pushing force can be obtained, the probability that the tire is retained in the channel 110 is reduced, and the accuracy of single tire placement is further ensured.

To sum up, the utility model provides a singly put ware, singly put the ware setting on the transfer chain, including swing arm mechanism, including first swing arm subassembly and second swing arm subassembly, first swing arm subassembly reaches second swing arm subassembly symmetry sets up in order to constitute a passageway that supplies article to come in and go out, the passageway has entry and export, first swing arm subassembly reaches second swing arm subassembly swing, so that the entry reaches export expansion or shrink to, the state of expansion or shrink is opposite. And the clamping arm mechanism comprises a first clamping arm component and a second clamping arm component, the first clamping arm component and the second clamping arm component are respectively arranged at the end parts of the first swing arm component and the second swing arm component corresponding to the inlets, and the first clamping arm component and the second clamping arm component extend outwards along the direction deviating from the channel so as to clamp the articles. The first clamping arm assembly and the second clamping arm assembly enable the range of the tire captured by the swing arm mechanism to be increased. Even if the tire is not on the central line of the conveying line, the running track of the tire is corrected under the action of the first clamping arm assembly or the second clamping arm assembly, so that the tire enters the inlet of the swing arm mechanism. When the swing arm mechanism stops the tire, the tire can not be separated from the inlet of the swing arm mechanism even if forward force is always applied to the tire on the conveying line because the tire is clamped by the first clamping arm assembly and the second clamping arm assembly. The probability of the tire entering the channel is increased, and the accuracy of single placement of the tire is ensured. First arm lock subassembly and second arm lock subassembly lean on the passageway inboard to set up the gyro wheel, and the gyro wheel rotates, can reduce the frictional force of tire surface and gyro wheel, reduces the probability that produces the mar on the tire.
