Abstract

A temporary storage mechanism (100) and a conveying device. The temporary storage mechanism comprises jacking assemblies (110) and supporting assemblies. Each supporting assembly comprises a first mounting base (121), a second mounting base (122), a first support block (123), and a second support block (124). The first support block and the second support block have a movement trend of approaching each other, and an overhead passage allowing a product to pass through is formed between the first support block and the second support block and a conveyor line (200). In the product jacking process of the jacking assembly, the product can abut against the first support block and the second support block, and push the first support block and the second support block to move away from each other for allowing the product to pass through. The first support block and the second support block get close to each other and support the product, the jacking assembly returns to an initial position, and a subsequent product can still pass through the overhead passage formed by the first support block, the second support block, and the conveyor line, without needing to wait for the product supported by the first support block and the second support block to be taken away and then convey subsequent products, thereby effectively improving the conveying efficiency of products.

Description

Cache mechanism and conveying equipment Technical Field

[0001] The present application relates to the technical field of automation equipment, and in particular to a buffer mechanism and conveying equipment. Background Art

[0002] When processing products conveyed on a flow line, it is usually necessary to first block the product's continued conveyance with a blocking structure, confining the product to a lifting station. The lifting structure then lifts the product up, and the transport mechanism then removes the product for processing. While waiting for the transport mechanism to remove the product, the lifting structure limits the flow line from being able to convey new products. This requires waiting for the product to be removed and the lifting structure to be lowered before new products can be conveyed.

[0003] When multiple lifting stations are set up on the flow line, if the lifting structure at the front lifting station lifts the product, the subsequent lifting stations need to wait for the new product to be delivered after the front lifting structure descends, resulting in low product delivery efficiency.

[0004] Summary of the Invention

[0005] Based on this, it is necessary to provide a cache mechanism and conveying equipment that can avoid the jacking structure affecting the conveying of subsequent products and improve the conveying efficiency after the existing products are lifted by the jacking structure, resulting in low conveying efficiency.

[0006] A cache mechanism, comprising:

[0007] A lifting assembly, used to lift the product conveyed by the flow line to remove it from the flow line; and

[0008] The lifting assembly includes a first mounting seat, a second mounting seat, a first supporting block, and a second supporting block, wherein the first mounting seat and the second mounting seat are respectively arranged on both sides of the streamline, and the first supporting block and the second supporting block are respectively movably connected to the first mounting seat and the second mounting seat so as to move closer to or away from each other during movement;

[0009] In which, the first supporting block and the second supporting block have a tendency to move closer to each other, and an overhead channel for the product to pass through is formed between the first supporting block and the second supporting block and the streamline; in the process of the jacking assembly lifting the product, the product can abut against the first supporting block and the second supporting block, and push the first supporting block and the second supporting block away from each other to allow the product to pass through.

[0010] With this buffer mechanism, after the lifting assembly lifts the product past the first and second support blocks, the first and second support blocks move closer together to support the product. The lifting assembly then returns to its initial position, allowing subsequent products to pass through the overhead passage formed by the first and second support blocks and the streamline. This eliminates the need for the streamline to wait for the products supported by the first and second support blocks to be removed before delivering subsequent products, effectively improving product delivery efficiency.

[0041] As shown in FIG. 1 and FIG. 2 , an embodiment of the present application provides a cache mechanism 100 , including a lifting assembly 110 and a lifting assembly.

[0042] Lifting assembly 110 is used to lift products conveyed by flow line 200 and remove them from flow line 200. The lifting assembly includes a first mounting base 121, a second mounting base 122, a first support block 123, and a second support block 124. First mounting base 121 and second mounting base 122 are respectively positioned on either side of flow line 200. First support block 123 is movably connected to first mounting base 121, and second support block 124 is movably connected to second mounting base 122. First support block 123 and second support block 124 can move away from or toward each other during movement.

[0043] Among them, the first supporting block 123 and the second supporting block 124 have a tendency to move closer to each other, and an overhead channel for the product to pass through is formed between the first supporting block 123 and the second supporting block 124 supporting the product and the streamline 200; in the process of the jacking assembly 110 lifting the product, the product can abut against the first supporting block 123 and the second supporting block 124, and push the first supporting block 123 and the second supporting block 124 away from each other to allow the product to pass.

[0044] When streamline 200 conveys the product to lifting assembly 110, lifting assembly 110 lifts the product away from streamline 200, causing the product to push first support block 123 and second support block 124 away from each other until the product passes through. After the product passes through, because first support block 123 and second support block 124 tend to move toward each other, when lifting assembly 110 lowers the product, the product is supported by both first support block 123 and second support block 124, which are positioned close to each other. At the same time, an overhead passage for the product to pass through is formed between first support block 123, second support block 124 and streamline 200. Therefore, after supporting the product, first support block 123 and second support block 124 will not affect the subsequent conveyance of the product.

[0045] As can be seen, using the above-described buffer mechanism 100, after the lifting assembly 110 lifts the product past the first supporting block 123 and the second supporting block 124, the first supporting block 123 and the second supporting block 124 approach each other and support the product, and then the lifting assembly 110 returns to its initial position, while subsequent products on the streamline 200 can still be conveyed through the overhead passage formed by the first supporting block 123, the second supporting block 124, and the streamline 200. In this way, the streamline 200 does not need to wait for the products supported by the first supporting block 123 and the second supporting block 124 to be removed before conveying subsequent products, effectively improving product conveying efficiency.

[0046] It needs to be explained that, assuming that the products transported by the streamline 200 can pass through two lifting stations, a cache mechanism 100 can be set at the previous lifting station, or a cache mechanism 100 can be set at both lifting stations, so that while the products are cached at the cache mechanism 100, the streamline 200 can continue to transport the products to the next lifting station.

[0047] Of course, when the product conveyed by the streamline 200 can pass through more than two lifting stations, a cache mechanism 100 can be set at all lifting stations, or a cache mechanism 100 can be set at all lifting stations except the last one to ensure the conveying efficiency of the product.

[0048] In one embodiment, the buffer mechanism 100 further includes a blocking assembly 130. The blocking assembly 130 is used to block the products on the flow line 200 from continuing to be conveyed, so as to ensure that the products stay at the lifting assembly 110, thereby facilitating the lifting assembly 110 to lift the products out of the flow line 200.

[0049] It should be noted that the blocking assembly 130 is a conventional mechanism and will not be described in detail here.

[0050] In one embodiment, the lifting assembly 110 includes a lifting drive 111 and a lift plate 112. The lifting drive 111 is positioned below the flow line 200 and connected to the lift plate 112 to drive the lift plate 112 upward and downward. During the lift, the lift plate 112 supports and lifts the products on the flow line 200. After the products are supported on the first support block 123 and the second support block 124, the lift plate 112 descends back to its initial position to avoid disrupting the continued transport of the products on the flow line 200.

[0051] Optionally, the lifting drive member 111 is a cylinder. Of course, in other embodiments, the lifting drive member 111 can also be other driving mechanisms.

[0052] In one embodiment, the first supporting block 123 reciprocates between the first passing position and the first supporting position, and the first supporting block 123 has a tendency to move toward the first supporting position, and the second supporting block 124 reciprocates between the second passing position and the second supporting position, and the second supporting block 124 has a tendency to move toward the second supporting position.

[0053] When the first supporting block 123 and the second supporting block 124 move to the first passing position and the second passing position respectively, the product can pass between the first supporting block 123 and the second supporting block 124; when the first supporting block 123 and the second supporting block 124 move to the first supporting position and the second supporting position respectively, the first supporting block 123 and the second supporting block 124 can jointly support the product.

[0054] In the first embodiment, the first support block 123 is rotatably connected to the first mounting base 121 and can rotate toward the first supporting position under the action of gravity. The second support block 124 is rotatably connected to the second mounting base 122 and can rotate toward the second supporting position under the action of gravity. In this way, the first support block 123 and the second support block 124 have a tendency to move toward each other under the action of gravity.

[0055] It can be understood that initially, the support block (first support block 123 or second support block 124) is located at the supporting position (first supporting position or second supporting position), and the top plate 112 pushes the support block to the passing position (first passing position or second passing position) as the product is lifted. After the product passes through, the support block returns to the supporting position under the action of gravity, and then the top plate 112 descends, and the product is supported on the support block.

[0056] In the second embodiment, the first supporting block 123 is rotatably connected to the first mounting seat 121, and the second supporting block 124 is rotatably connected to the second mounting seat 122. The lifting assembly further includes a first elastic member 125 and a second elastic member 125. The first elastic member 125 is connected between the first mounting seat 121 and the first supporting block 123 to provide a force to rotate the first supporting block 123 toward the first supporting position. The second elastic member 125 is connected between the second mounting seat 122 and the second supporting block 124 to provide a force to rotate the second supporting block 124 toward the first supporting position.

[0057] It can be understood that in this embodiment, the first elastic member 125 and the second elastic member 125 are used to provide a force that brings the first support block 123 and the second support block 124 closer to each other, ensuring that after the product pushes the first support block 123 and the second support block 124 to the first passing position and the second passing position respectively, the first support block 123 and the second support block 124 can approach each other to return to the first supporting position and the second supporting position respectively.

[0058] As the top plate 112 lifts the product, the product contacts the support block, pushing it toward the passage position, overcoming the force of the elastic member 125 (either the first elastic member 125 or the second elastic member 125). After the product passes through, the support block returns to the supporting position under the action of the elastic member 125. The top plate 112 then descends, and the product is supported by the support block.

[0059] In the third embodiment, the first support block 123 and the second support block 124 are both reciprocally movable along a direction Y perpendicular to the conveying direction X of the streamline 200, so as to move closer to or further away from each other during movement. The lifting assembly further includes a first elastic member 125 and a second elastic member 125. The first elastic member 125 is connected between the first mounting seat 121 and the first support block 123 to provide a force to move the first support block 123 toward the first supporting position. The second elastic member 125 is connected between the second mounting seat 122 and the second support block 124 to provide a force to move the second support block 124 toward the second supporting position.

[0060] It should be noted that the support block is provided with an abutment slope 1261. When the top plate 112 lifts the product, the product contacts the abutment slope 1261, providing a force for the support block to move toward the passing position. Taking Figure 3 as an example, in the second embodiment, as the product moves upward from bottom to top, the product contacts the abutment slope 1261, pushing the support block counterclockwise. After the product passes through, the support block, under the action of the elastic member 125, rotates clockwise back to the supporting position, supporting the product above.

[0061] Alternatively, the elastic member 125 may be a spring or other elastic structure. Meanwhile, the mounting base (the first mounting base 121 or the second mounting base 122 ) and the supporting block are provided with mounting holes, into which the elastic member 125 may be mounted to prevent the elastic member 125 from falling off.

[0062] In one embodiment, the first mounting seat 121 is provided with a first limiting structure 127, with which the first supporting block 123 can abut against during its movement, and the first limiting structure 127 is used to limit the first supporting block 123 between the first passing position and the first supporting position. The second mounting seat 122 is provided with a second limiting structure 127, with which the second supporting block 124 can abut against during its movement, and the second limiting structure 127 is used to limit the second supporting block 124 between the second passing position and the second supporting position.

[0063] Referring to Figure 3 , in the second embodiment, a first abutting portion 1262 and a second abutting portion 1263 are respectively provided at each end of the support block. During counterclockwise rotation of the support block, the first abutting portion 1262 can abut against the limiting structure 127 (either the first limiting structure 127 or the second limiting structure 127) to limit the support block to the passing position. During clockwise rotation of the support block, the second abutting portion 1263 can abut against the limiting structure 127 to limit the support block to the supporting position. An elastic member 125 is connected to the end of the support block closest to the first abutting portion 1262.

[0064] It is understandable that the first embodiment may refer to the structure of the second embodiment, as long as it is ensured that the supporting block can return to the supporting position under the action of gravity.

[0065] At the same time, in the third embodiment, the limiting structure 127 may include two baffles, which are arranged at intervals along a direction Y perpendicular to the conveying direction X of the streamline 200, and the supporting block moves back and forth between the two baffles, thereby limiting the supporting block between the passing position and the supporting position.

[0066] It should be noted that in the first embodiment and the second embodiment, the supporting block is rotatably connected to the mounting seat via the rotating shaft 128 .

[0067] Please refer to Figures 1 and 3 to 5 at the same time. In one embodiment, the cache mechanism 100 also includes a positioning component, which is arranged above the streamline 200 and is used to position the product supported by the lifting component, thereby ensuring that the subsequent transport mechanism can accurately grasp the product.

[0068] In one embodiment, the positioning assembly includes a first positioning block 141, a second positioning block 142, a third positioning block 143, and a fourth positioning block 144. The first positioning blocks 141 and the second positioning blocks 142 are arranged at intervals along the conveying direction X of the streamline 200 and are used to position products in the conveying direction X of the streamline 200. The third positioning block 143 and the fourth positioning block 144 are respectively provided on both sides of the streamline 200 and are used to position products in a direction Y perpendicular to the conveying direction X of the streamline 200.

[0069] Furthermore, the first positioning block 141 has a first positioning surface 145 and a first guide surface 146 on the side facing the second positioning block 142, and the second positioning block 142 has a second positioning surface 145 and a second guide surface 146 on the side facing the first positioning block 141. The first positioning surface 145 and the second positioning surface 145 are used to position the product, the first guide surface 146 is inclined relative to the first positioning surface 145, and the second guide surface 146 is inclined relative to the second positioning surface 145, and the first guide surface 146 and the second guide surface 146 are used to guide the product into between the first positioning surface 145 and the second positioning surface 145.

[0070] The third positioning block 143 has a third positioning surface 145 and a third guide surface 146 on the side facing the fourth positioning block 144, and the fourth positioning block 144 has a fourth positioning surface 145 and a fourth guide surface 146 on the side facing the third positioning block 143. The third positioning surface 145 and the fourth positioning surface 145 are used to position the product, the third guide surface 146 is inclined relative to the third positioning surface 145, and the fourth guide surface 146 is inclined relative to the fourth positioning surface 145, and the third guide surface 146 and the fourth guide surface 146 are used to guide the product into between the third positioning surface 145 and the fourth positioning surface 145.

[0071] It is understood that the conveying direction X of the streamline 200 and the perpendicular direction Y are both horizontal, so the positioning surfaces 145 (the first positioning surface 145, the second positioning surface 145, the third positioning surface 145, and the fourth positioning surface 145) are all vertical planes, and the positioning surfaces 145 enclose a positioning space to position the product horizontally. At the same time, the inclined guide surfaces 146 (the first guide surface 146, the second guide surface 146, the third guide surface 146, and the fourth guide surface 146) are used to guide the product into the positioning space to achieve product positioning.

[0072] Furthermore, when the product enters the positioning space, the guide surface 146 and the positioning surface 145 contact the outside of the product. Compared to positioning methods using positioning pins, this positioning assembly can position the product without the need for positioning holes or other structures on the product, thus ensuring product integrity. This also allows the cache mechanism 100 to be applied to a wider range of products requiring guaranteed integrity, thus improving its applicability.

[0073] Furthermore, the first positioning block 141 includes two first guide surfaces 146, which are respectively connected to the two ends of the first positioning surface 145 along the vertical direction, and the two first guide surfaces 146 are symmetrically arranged. The second positioning block 142 includes two second guide surfaces 146, which are respectively connected to the two ends of the second positioning surface 145 along the vertical direction, and the two second guide surfaces 146 are symmetrically arranged. The third positioning block 143 includes two third guide surfaces 146, which are respectively connected to the two ends of the third positioning surface 145 along the vertical direction, and the two third guide surfaces 146 are symmetrically arranged. The fourth positioning block 144 includes two fourth guide surfaces 146, which are respectively connected to the two ends of the fourth positioning surface 145 along the vertical direction, and the two fourth guide surfaces 146 are symmetrically arranged.

[0074] As a result, when the top plate 112 lifts the product, the guide surface 146 below the positioning surface 145 guides the product into the positioning space. If the product rises higher than the height of the positioning surface 145, the guide surface 146 above the positioning surface 145 can also guide the product as it falls back into the positioning space. At the same time, if the height of the positioning surface 145 is increased to ensure that the product is raised and lowered within the positioning space, the product will constantly rub against the positioning surface 145 during the lifting process, causing the product to easily wear.

[0075] In one embodiment, the positioning assembly also includes a first positioning seat 147 and a second positioning seat 148. The first positioning seat 147 and the second positioning seat 148 are respectively arranged on both sides of the streamline 200. The first mounting seat 121 is arranged on the first positioning seat 147, the second mounting seat 122 is arranged on the second positioning seat 148, the third positioning block 143 is arranged on the first positioning seat 147, and the fourth positioning block 144 is arranged on the second positioning seat 148.

[0076] Furthermore, the positioning assembly includes two groups of first positioning blocks 141 and two groups of second positioning blocks 142, wherein one group of first positioning blocks 141 and one group of second positioning blocks 142 are arranged at intervals on the first positioning seat 147 along the conveying direction X of the streamline 200, and another group of first positioning blocks 141 and another group of second positioning blocks 142 are arranged at intervals on the second positioning seat 148 along the conveying direction X of the streamline 200.

[0077] Of course, when the first positioning block 141 and the second positioning block 142 include only one set, the first positioning block 141 and the second positioning block 142 can be set on the first positioning seat 147 or the second positioning seat 148 .

[0078] Specifically, in the embodiment shown in FIG1 , there is one first positioning block 141 in each group, and there is one second positioning block 142 in each group. Of course, in other embodiments, there may be multiple first positioning blocks 141 and multiple second positioning blocks 142 in each group, and the multiple first positioning blocks 141 and multiple second positioning blocks 142 in each group are arranged at intervals along a direction Y perpendicular to the conveying direction X of the streamline 200.

[0079] In one embodiment, the positioning assembly includes at least two third positioning blocks 143 and at least two fourth positioning blocks 144 , and the at least two third positioning blocks 143 and the at least two fourth positioning blocks 144 are arranged at intervals along the conveying direction X of the streamline 200 .

[0080] To facilitate understanding of the technical solution of the present application, the working process of the cache mechanism 100 in the second embodiment is described with reference to FIG1 :

[0081] The product is transported along streamline 200, and the blocking mechanism blocks the product at the lifting station. The lifting drive 111 then drives the top plate 112 upward, carrying the product with it. During this rise, the product abuts against the support block's abutting slope 1261, as well as the guide surface 146 and positioning surface 145 of the positioning block, pushing the support block toward the passing position and achieving positioning under the action of the positioning block.

[0082] After the product passes through the support block, it returns to its supporting position under the action of elastic member 125. Next, top plate 112 descends, supporting the product on the support block during its descent. The product supported by the support block is positioned in the positioning space, ensuring that the subsequent handling mechanism can accurately grasp the product. After top plate 112 returns to its original position, an overhead passage is formed between the support block and flow line 200, allowing subsequent products to pass through without interfering with the transportation of subsequent products.

[0083] Based on the above-mentioned cache mechanism 100 , the present application further provides a conveying device, which includes a streamline 200 and the above-mentioned cache mechanism 100 .

[0084] The cache mechanism 100 and conveying device provided in this application have at least the following advantages:

[0085] 1. The product can be supported by the support block, and an overhead passage for the product to pass through is formed between the support block and the flow line 200, thereby preventing the lifting assembly 110 from obstructing the transportation of subsequent products and improving the product transportation efficiency;

[0086] 2. The outer surface of the product is in contact with the positioning block, so there is no need to open positioning holes on the product, ensuring the integrity of the product.

[0087] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
