Description

Technical Field

[0001] The utility model relates to a transmission device. Background Art

[0002] When the product on the transmission device reaches the processing station, the transmission device will stop the product from being transmitted forward by braking. However, under the action of inertia, the product will continue to slide forward and deviate from the processing station. In the prior art, the transmission device is usually provided with a blocking mechanism, which is provided with a baffle that can reciprocate. The impact between the baffle and the product is used to offset the inertia of the product, thereby preventing the product from sliding forward, so that the product can accurately stay at the processing station.

[0003] The blocking mechanism is usually equipped with a guide assembly to provide movement guidance for the baffle and improve the stability of the baffle movement. However, as the frequency of impact increases, the baffle is very likely to deform, so that the coordination between the baffle and the guide assembly will be affected, causing the movement of the baffle to become stuck or even stuck, making the blocking mechanism unable to work normally and causing damage to the components that drive the baffle movement.

DETAILED DESCRIPTION

[0033] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments, so that the advantages and features of the utility model can be more easily understood by those skilled in the art. Obviously, the embodiments described in this application are only part of the embodiments of the application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0034] See also Figure 1 A transmission device is shown, which includes a transmission member 100 and a blocking mechanism 200, wherein the transmission member 100 is used to transmit objects along a first direction, a transmission channel 120 is formed on the transmission member 100, and the objects are transmitted in the transmission channel 120, and the blocking mechanism 200 is used to block the objects from being transmitted forward so that the objects can stay at a preset position.

[0035] See also Figures 2 to 4 As shown, the blocking mechanism 200 includes a baffle 1 and a driving assembly 2 for driving the baffle 1 to reciprocate along a second direction, and the second direction is perpendicular to the first direction. The blocking mechanism 200 has at least a first state and a second state. When the blocking mechanism 200 is in the first state, at least part of the baffle 1 extends into the transmission channel 120. In this state, the inertia of the object is offset by the collision between the baffle 1 and the object, so that the object stops. When the blocking mechanism is in the second state, the baffle 1 is retracted along the second direction and separated from the transmission channel 120. In this state, the baffle 1 does not affect the transmission of the object.

[0036] The blocking mechanism 200 also includes a guide assembly 3, which is used to provide guidance for the reciprocating motion of the baffle 1, and can also improve the strength of the baffle 1 when the baffle 1 collides with an object. The guide assembly 3 includes at least a guide wheel 31 and a guide surface 321, wherein the guide surface 321 extends along the second direction, and the guide surface 321 includes two guide surfaces 321 spaced apart along the first direction. The guide wheel 31 is located between the two guide surfaces 321, and along the third direction, the guide wheel 31 is rotatably arranged on one side of the guide surface 321 around the first rotation center line X1, the first direction, the second direction and the third direction are perpendicular to each other, and the extension direction of the first rotation center line X1 is parallel to the first direction. A guide groove 33 extending along the second direction is formed between the two guide surfaces 321 and the guide wheel 31, and the baffle 1 is inserted into the guide groove 33 in a sliding manner.

[0037] As the number of collisions increases, the baffle 1 is very likely to deform, and the resulting deformation will affect the coordination between the guide assembly 3 and the baffle 1, causing the relative movement between the baffle 1 and the guide assembly 3 to become stuck, and in severe cases, even causing the baffle 1 to become stuck. In this embodiment, the two guide surfaces 321 spaced apart along the first direction can not only provide motion guidance for the baffle 1, but also enhance the strength and stability of the baffle 1 when the baffle 1 is subjected to collisions. At the same time, the two guide surfaces 321 can also limit the deformation of the baffle 1 along the first direction, avoiding the baffle 1 from becoming stuck with the two guide surfaces 321. At the same time, the guide wheel 31 is used for guidance and limiting in the third direction. The guide wheel 31 can adapt to the deformation of the baffle 1 in this direction and will not affect the movement of the baffle 1, thereby avoiding stuck.

[0038] In this embodiment, the guide assembly 3 includes two guide members 32 arranged at intervals along the first direction, and the guide members 32 extend along the second direction. The two surfaces of the two guide members 32 that are arranged opposite to each other and face each other constitute the above-mentioned two guide surfaces 321. In this embodiment, the side of the baffle 1 is inserted into the guide groove 33, and the outer peripheral surface of the guide wheel 31 is in point contact with the baffle 1. There is rolling friction between the guide wheel 31 and the baffle 1, which can effectively reduce the resistance to the movement of the baffle 1. The guide surface 321 on the guide member 32 is in surface contact or line contact with the baffle 1, and there is sliding friction between the guide member 32 and the baffle. The line contact or surface contact limits the freedom of the baffle 1 to move along the first direction. In addition to guiding and improving the strength of the baffle, it can also prevent the baffle 1 from deforming in the mating position. However, the point contact does not completely limit the freedom of the baffle 1 to move along the third direction, allowing the baffle 1 to deform to a certain extent in the third direction.

[0039] In this embodiment, the guide assembly 3 includes two groups arranged on two different sides of the length direction of the baffle 1, the notches of the two guide grooves 33 are opposite, and the two side parts arranged on the different sides of the length direction of the baffle 1 are respectively inserted into the two guide grooves 33. Specifically, the baffle 1 extends along the third direction, and along the third direction, the baffle 1 is located between the guide wheels 31 on both sides, and the guide member 32 is a clamping plate extending along the second direction, and the guide member 32 is arranged on different sides of the thickness direction of the baffle 1. The guide wheels 31 on both sides are in contact with the two ends of the baffle 1. When the baffle 1 moves along the second direction, the guide wheels 31 on both sides can prevent the displacement of the baffle 1 along the third direction, and play a guiding and limiting role.

[0040] In this embodiment, see Figure 8 , Fig. 9 As shown, each guide assembly 3 has two guide wheels 31 spaced apart along the second direction. During the movement of the baffle 1, the guide wheels 31 on both sides are frame-type four-point contacts, which can provide more stable guidance. In this embodiment, the baffle 1 has a symmetric plane extending along the first direction and along the second direction, and the guide wheels 31 on both sides are symmetrically arranged along the symmetric plane, so as to better maintain the stability of the baffle 1.

[0041] In this embodiment, the baffle 1 is arranged to move in the up-down direction, that is, the second direction is the up-down direction, and the transmission channel 120 is located above the transmission member 100. When the blocking mechanism 200 is in the second state, the blocking mechanism 200 is located as a whole below the transmission member 100. By driving the baffle 1 to move upward and extend into the transmission channel, the blocking mechanism 200 is converted to the first state and the blocking function is realized.

[0042] In this embodiment, see Figure 6 , Fig.11 As shown, along the second direction, the two guide wheels 31 of each guide assembly 3 are arranged on different sides of the guide surface 321, that is, the two guide wheels 31 are arranged on the upper and lower sides of the guide member 32, which further improves the stability of the baffle 1 during the up and down lifting process of the baffle 1. Figure 6 , Fig.11 As shown, in this embodiment, when the blocking mechanism switches between the first state and the second state, both ends of the baffle 1 are always in contact with the guide wheels 31, thereby ensuring the stability of the lifting and lowering of the baffle 1.

[0043] In this embodiment, see Figure 1 , Figure 8As shown, along the third direction, the blocking mechanism 200 has two side brackets 4 disposed on both sides, the side brackets 4 extend in the up-down direction and are located below the transmission member 100, and the lower part of the side brackets 4 is fixed on the transmission device. The guide assembly 3 includes a mounting seat 34, the mounting seat 34 is fixed on the upper part of the side bracket 4, the guide member 32 is respectively fixed on the side bracket 4 and the mounting seat 34, and the guide wheel 31 is rotatably disposed on the mounting seat 34. Specifically, the two guide wheels 31 are disposed on the upper part and the lower part of the mounting seat 34.

[0044] Specifically, the mounting base 34 is composed of a first plate 341 and a second plate 342 that are integrally arranged. Fig.12 As shown, the first plate 341 and the second plate 342 are both T-shaped, the horizontal sides of the two T-shaped plates are fixed together, and the first plate 341 and the second plate 342 form a right angle. The second plate 342 includes a first portion 342a and a second portion 342b that are integrally arranged. Along the second direction, the length of the first portion 342a is greater than the second portion 342b, and the second portion 342b is fixedly connected to the side bracket 4. A mounting groove 343 is formed between the first plate 341, the second plate 342 and the side bracket 4, and the mounting groove 343 is U-shaped with the notch facing the baffle 1.

[0045] See also Figure 7 As shown, in this embodiment, two guide members 32 are fixedly arranged in the mounting groove 343, one of which is fixedly connected to the side bracket 4, and the other is fixedly connected to the first plate 341. The two guide wheels 31 are rotatably connected to the first part 342a, respectively, and along the second direction, the two guide wheels 31 are arranged on different sides of the second part 342b, specifically, one of the guide wheels 31 is located above the second part 342b, and the other guide wheel 31 is located below the second part 342b and between the first part 342a and the side bracket 4.

[0046] In this embodiment, see Figure 7 As shown, along the second direction, the length of the guide member 32 is similar to the length of the second portion 342b. Figure 4 , Figure 5 As shown, along the third direction, the guide wheel 31 extends into the mounting groove 343 and extends between the two guide members 32 .

[0047] In this embodiment, see Fig.10 As shown, the driving assembly 2 includes an output shaft 211 that can move along the second direction, and the output shaft 211 is rotatably connected to the baffle 1 around the second rotation center line X2, and the extension direction of the second rotation center line X2 is perpendicular to the first direction, and the extension direction of the second rotation center line X2 is perpendicular to the second direction. In this way, the angle error between the actual movement direction of the baffle 1 and the extension direction of the guide groove 33 can be offset.

[0048] In this embodiment, the driving assembly 2 also includes a driving member 21 for driving the output shaft 211 to move, the transmission device includes a device body, the transmission member 100 and the blocking mechanism 200 are both arranged on the device body, the driving member 21 is rotatably arranged on the device body around the third rotation center line X3, and the third rotation center line X3 is parallel to the second rotation center line X2. Specifically, the driving assembly 2 is provided with a fixed seat 22, the fixed seat 22 is fixedly connected to the transmission device, the driving member 21 is a cylinder or an electric cylinder, and the lower part of the driving member 21 is rotatably connected to the fixed seat 22 around the third rotation center line X3. When the baffle 1 is deformed due to the impact, the driving direction and mode of the driving assembly 2 must also be adjusted, so that the baffle 1 can be driven up and down more smoothly to avoid damage to the driving assembly 2 itself. In this embodiment, the driving member 21 is rotatably arranged on the transmission device, and the output shaft 211 and the baffle 1 are rotatably arranged. In addition to being able to offset errors, it can also have better adaptability and prevent damage to the driving member 21.

[0049] In this embodiment, the transmission member 100 includes a plurality of transmission rollers 110 sequentially distributed along a first direction, the transmission rollers 110 are arranged at intervals, and the blocking mechanism 200 is in the second state, and the blocking mechanism 200 is located below the transmission rollers 110; when the blocking mechanism 200 is in the first state, part of the baffle 1 extends from the gap between the transmission rollers 110 to above the transmission rollers 110.

[0050] The transmission device of this embodiment can be a transmission track, or the transmission device can be a transmission trolley. The blocking mechanism 200 arranged on the transmission device has a simple structure. The guide components 3 located on both sides of the baffle 1 not only provide movement guidance for the baffle 1 to rise and fall, but also the guide member 32 can withstand the impact when the baffle 1 collides with an object to ensure the strength of the baffle 1. At the same time, the guide members 32 arranged on the two sides of the thickness direction can also limit the deformation of the baffle 1 along the first direction to avoid the baffle 1 and the guide member 32 from getting stuck. At the same time, the guide wheels 31 arranged on the two sides of the length direction of the baffle 1 can not only maintain the stability of the baffle 1 rising and falling, but also will not affect the normal operation of the guide wheels 31 even if the baffle 1 is slightly deformed in the third direction.
