Description

Technical Field

[0001] This invention belongs to the field of automation equipment technology, specifically relating to an automatic tray sorting device for blister packs and its usage method. Background Technology

[0002] With the improvement of automation, stacked blister trays are often separated layer by layer using blister tray separating equipment. The separated blister trays are used to transfer specific parts, thereby improving production efficiency.

[0003] Existing blister tray splitting equipment mainly includes a receiving assembly and a splitting assembly. During splitting, the receiving assembly moves up to the bottom of the splitting assembly, the splitting assembly retracts, and the bottommost blister tray falls onto the receiving assembly. Then, the receiving assembly descends a distance equal to the thickness of one blister tray, the splitting assembly extends to lift the remaining blister trays, and the receiving assembly continues to move down to complete the splitting. For example, patent application number 202023346594.1 discloses a blister tray splitting equipment, including at least one set of oppositely arranged receiving assemblies. Each set of receiving assemblies includes a receiving drive component and a four-bar linkage with receiving plates connected to the receiving drive component. The receiving drive component drives the four-bar linkage to move the two oppositely arranged receiving plates together or apart to correspondingly receive or release the tray. The above structure can achieve tray separation in blister packs. However, it is clear that this tray separation mechanism is suitable for thicker blister packs. It is not practical for thinner blister packs, especially for blister packs for black vinyl USB flash drives and TF cards, which cannot be accurately separated and have low reliability.

[0026] S1. Take several blister trays and place them into the positioning assembly for positioning. The first support plate, the second support plate, and the third support plate support the several blister trays.

[0027] S2. The power source is started. The output shaft of the power source extends and drives the first displacement plate and the second displacement plate to move to the left. The second displacement plate drives the first material support plate to move to the left. The second displacement plate drives the second rack of the second material support plate to move to the right through the first rack and gear and drives the second material support plate to move to the right. The second displacement plate also drives the material distribution plate to move to the left. The material distribution plate extends into the space between the lowest blister tray and the blister tray adjacent to it.

[0029] S4. The output shaft of the power source continues to extend, and the end of the blister tray located at the bottom near the power source falls from the first material support plate and the second material support plate to the bottom of the mounting base inside the material passage hole.

[0030] S5. The output shaft of the power source extends to its maximum. The first swing arm swings to the left and drives the first swing arm, the third material support plate and the second swing arm to move away from the power source. The end of the blister tray located at the bottom away from the power source falls from the third material support plate to the bottom of the mounting base in the material passage hole. At this time, the blister tray at the bottom is split and falls to the bottom of the mounting base.

[0031] After actions S6 and S5 are completed, the output shaft of the power source is reset, the first cam drive drives the first material distribution plate to reset, the second cam drive drives the second material distribution plate to reset, the material distribution plate is reset, the first material support plate, the second material support plate and the third material support plate support the remaining several blister trays, and then steps S2 to S5 are repeated.

[0032] By adopting the above technical solution, the present invention has the following beneficial effects:

[0033] (1) The present invention is provided with a positioning component, an active plate-separating component, a transmission component, a driven plate-separating component, and a cam-assisted plate-separating mechanism. The positioning component, the active plate-separating component, the transmission component, the driven plate-separating component, and the cam-assisted plate-separating mechanism can cooperate with each other to complete the plate separation.

[0049] In this embodiment, the present invention proposes an automatic tray-separating device for blister trays 1 and its usage method, which can accurately separate trays and is suitable for thinner blister trays 1, especially for blister trays 1 for black vinyl USB flash drives and TF cards.

[0050] like Figure 1-6 As shown, in one embodiment of the present invention, the automatic tray-separating device for blister trays 1 includes a mounting base, a positioning component, a power tray-separating mechanism, and a cam-assisted tray-separating mechanism. The mounting base has a mounting cavity, and a material passage hole 2 is provided at the center of the top surface of the mounting base, extending downwards through the mounting cavity and to the bottom surface of the mounting base. The positioning component is disposed on the top surface of the mounting base and is used to position several blister trays 1. The power tray-separating mechanism is disposed within the mounting cavity of the mounting base and extends downwards through the mounting cavity to below the bottom surface of the mounting base. The power tray-separating mechanism is used for sequential tray separation. The cam-assisted tray-separating mechanism is disposed on the power tray-separating mechanism and extends out of the top surface of the mounting base. The auxiliary plate-separating mechanism assists the power plate-separating mechanism in completing the plate-separating action. The mounting base includes a top plate 3, a bottom plate 4, a left side plate 5, a front side plate 6, a right side plate 7, and a rear side plate 8 that are enclosed together. That is, the mounting base is a hexahedral structure, and the top plate 3, bottom plate 4, left side plate 5, front side plate 6, right side plate 7, and rear side plate 8 enclose a mounting cavity. The material passage hole 2 is located in the middle of the top plate 3 and extends downwards through the mounting cavity and the bottom plate 4. The positioning assembly includes several positioning plates 9, which are connected to the top surface of the top plate 3 and extend into the material passage hole 2. The several positioning plates 9 are arranged enclosed along the material passage hole 2. (See reference [link to documentation] for details.) Figure 3 The positioning plates 9 can be set in eight positions, with four on the left and four on the right. The positioning plates 9 are set vertically to accurately position several blister trays 1. The blister trays 1 can be neatly arranged and enter the material passage hole 2. The power dispensing mechanism includes an active dispensing assembly, a transmission assembly, and a driven dispensing assembly. The active dispensing assembly is connected to the driven dispensing assembly through the transmission assembly. The active dispensing assembly, the transmission assembly, and the driven dispensing assembly are all located in the mounting cavity, and the active dispensing assembly and the transmission assembly extend downward through the mounting cavity to below the bottom surface of the mounting base. The active dispensing assembly is used to dispense one end of the blister tray 1, and the driven dispensing assembly is used to dispense the other end of the blister tray 1.

[0051] In practical use, several blister trays 1 are neatly arranged and placed into the material passage hole 2, and then placed on the active and passive blister tray components. The active blister tray component starts to blister tray 1 at the bottom and slide one end of the blister tray 1 to the bottom of the mounting base. The active blister tray component also transmits a certain force to the passive blister tray component through the transmission component. The passive blister tray component is driven by the force and slides the other end of the blister tray 1 at the bottom. During this process, the cam-assisted blister tray mechanism assists in blister tray 1 ...

[0052] Please refer to Figure 4-6 This paper will describe in detail the specific structures of the active dispensing assembly, transmission assembly, and driven dispensing assembly of the present invention. The active dispensing assembly of the present invention includes a power source 10, a first displacement plate 11, a second displacement plate 12, a first material support plate 13, a second material support plate 14, a gear 15, and a dispensing plate 16. The power source 10 is disposed below the bottom surface of the mounting base and connected to the mounting base. A first connecting block 17 is connected to the output shaft of the power source 10. Specifically, in this invention, the power source 10 can be a cylinder. The first displacement plate 11 is provided with a displacement groove 19, which is sickle-shaped. The first displacement plate 11 is adapted to and connected to the transmission assembly through the displacement groove 19. The first displacement plate 11 and the first... Connecting block 17 is connected, and a rotating bearing 20 can be installed on the transmission assembly. The rotating bearing 20 is adapted to the displacement groove 19. The displacement groove 19 moves along the rotating bearing 20 under the action of the power source 10. The rotating bearing 20 transmits force to the transmission assembly. The second displacement plate 12 is slidably installed in the mounting cavity and is provided with a first rack 21. The second displacement plate 12 is connected to the first connecting block 17 through the second connecting block 18. The first displacement plate 11 is located below the base plate 4 of the mounting base, and the second displacement plate 12 is located above the base plate 4 of the mounting base and specifically in the mounting cavity. The second displacement plate 12 is slidably installed on the top surface of the base plate 4 through a slide rail slider structure. Figure 4 In the middle, the first rack 21 is located to the right of the second displacement plate 12. An opening slot is provided on the base plate 4. The second connecting block 18 moves in the opening slot. The first material support plate 13 is set in the mounting cavity and one end extends into the material passage hole 2. The other end of the first material support plate 13 is connected to the second displacement plate 12. Continuing with... Figure 4 For example, the first material support plate 13 is located above the base plate 4 and extends to the right into the material passage hole 2. The first material support plate 13 has a chamfered part 23 on the side near the material passage hole 2. The second material support plate 14 is slidably installed in the mounting cavity and one end extends into the material passage hole 2. The second material support plate 14 is provided with a second toothed rack 22. Figure 4For example, the second rack 22 is located on the left side of the second support plate 14. The second support plate 14 is also slidably mounted on the top surface of the base plate 4 via a slide rail slider structure. The second support plate 14 is located on the right side of the second displacement plate 12. The right end of the second support plate 14 is located in front of the first support plate 13. The right ends of the first support plate 13 and the second support plate 14 are flush. The second support plate 14 has a chamfered part 23 on the side near the material passage hole 2. More specifically, the front right side of the first support plate 13 and the rear right side of the second ejector plate have chamfered parts 23. The chamfered parts 23 facilitate the direct ejection of material from the first material passage hole 2 by the blister tray 1. The material support plate 13 and the second material support plate 14 fall off, and the gear 15 is rotated and mounted on the mounting base and meshes with the first rack 21 and the second rack 22 respectively. The power source 10 is used to drive the first rack 21 and the second rack 22 to move in opposite directions. The material distribution plate 16 is set on the second displacement plate 12 and is used for distributing the material. The second material support plate 14 is provided with a protruding locking groove 24, and the material distribution plate 16 is provided with a protrusion 25. The protrusion 25 is adapted to the protruding locking groove 24. When the material distribution plate 16 is working, the protrusion 25 can be locked on the protruding locking groove 24 to assist in positioning.

[0053] The transmission assembly of the present invention includes a first swing arm 26 and a second swing arm 27. Both the first swing arm 26 and the second swing arm 27 are located below the mounting base. One end of the first swing arm 26 is connected to the displacement groove 19 of the first displacement plate 11, and this end of the first swing arm 26 is slidably mounted on the mounting base. Specifically, this end of the first swing arm 26 is also slidably mounted on the bottom surface of the base plate 4 of the mounting base via a slide rail slider. A rotating bearing 20 is provided on the upper side of this end of the first swing arm 26 to adapt to the displacement groove 19. The other end of the first swing arm 26 is connected to the driven distributor assembly. One end of the second swing arm 27 is slidably mounted on the mounting base. The second swing arm 27 is also slidably mounted on the bottom surface of the base plate 4 of the mounting base via a slide rail slider structure. The other end of the second swing arm 27 is connected to the driven distributor assembly. The driven distributor assembly of the present invention includes a third material support plate 28. The third material support plate 28 is slidably mounted on the mounting base and is connected to the first swing arm 26 and the second swing arm 27. Specifically, the third material support plate 28 is also slidably mounted on the right side of the top surface of the base plate 4 of the mounting base via a slide rail slider structure. The third material support plate 28 has a chamfered part 23 on the side near the material passage hole 2. The chamfered part 23 facilitates the blister tray 1 to fall off the third material support plate 28.

[0054] During use, the material distribution plate 16 alone cannot support the remaining blister tray 1. Therefore, this invention also includes a cam-assisted blister tray distribution mechanism for support and auxiliary blister tray distribution. Please refer to [link / reference needed]. Figure 4-6The cam-assisted dividing mechanism includes: at least one first cam dividing assembly and at least one second cam dividing assembly. The first cam dividing assembly is mounted on a first rocker arm 26; the second cam dividing assembly is mounted on a second rocker arm 27. The first cam dividing assembly includes a first cam drive member 29 and a first dividing plate 30. The first cam drive member 29 is rotatably mounted on the first rocker arm 26, and the first dividing plate 30 is mounted on the first cam drive member 29. The first cam drive member 29 is used to drive the first dividing plate 30 to assist in dividing materials. The wheel-type distributor assembly includes a second cam drive 31 and a second distributor plate 32. The second cam drive 31 is rotatably mounted on a second rocker arm 27, and the second distributor plate 32 is mounted on the second cam drive 31. The second cam drive 31 is used to drive the second distributor plate 32 to assist in distributing materials. The free end of the first distributor plate 30 near the material passage hole 2 is provided with a first bent portion 33, and the free end of the second distributor plate 32 near the material passage hole 2 is provided with a second bent portion 34. In this invention, the first cam-type distributor assembly and the second cam-type distributor assembly each... Two sets of cam drives are provided, respectively mounted on the first swing arm 26 and the second swing arm 27. The first swing arm 26 and the second swing arm 27 have mounting slots. The first cam drive component 29 and the second cam drive component 31 are fitted and installed within the mounting slots. The first cam drive component 29 and the second cam drive component 31 can be passive components that rely on inertia and the transmission force on the first swing arm 26 and the second swing arm 27 to swing the first separating plate 30 and the second separating plate 32, thereby completing the auxiliary plate separation. The first cam drive component 29 and the second cam drive component 31 can be active components that rely on... The direct driving force and the transmission force on the first swing arm 26 and the second swing arm 27 swing the first dividing plate 30 and the second dividing plate 32 to complete the auxiliary dividing plate. The first bending part 33 and the second bending part 34 are designed to facilitate the insertion of several blister trays 1 to complete the dividing plate. The whole invention can be assembled on a conveyor line, so that the divided blister trays 1 can be directly dropped and conveyed away. Alternatively, after the active dividing plate assembly divides the plate and drops one end of the blister tray 1, the transmission belt drives the blister tray 1 to apply a force to the blister tray 1, making it easier for it to fall off the invention.

[0055] The present invention also discloses a method for using the above-mentioned automatic tray-separating device for blister trays 1, comprising the following steps:

[0056] S1. Take several blister trays 1 and place them into the positioning assembly for positioning. The first material support plate 13, the second material support plate 14 and the third material support plate 28 support the several blister trays 1.

[0057] S2, Power source 10 starts, the output shaft of power source 10 extends and drives the first displacement plate 11 and the second displacement plate 12 to move to the left. The second displacement plate 12 drives the first material support plate 13 to move to the left. The second displacement plate 12 drives the second rack 22 of the second material support plate 14 to move to the right through the first rack 21 and the gear 15, and drives the second material support plate 14 to move to the right. The second displacement plate 12 also drives the material distribution plate 16 to move to the left. The material distribution plate 16 extends into the space between the lowest blister tray 1 and the blister tray 1 adjacent to it. The first displacement plate 11 drives the first swing arm 26 to swing through the displacement groove 19.

[0058] S3. The first cam drive member 29 drives the first material distribution plate 30 to rotate towards the material passage hole 2, and the second cam drive member 31 drives the second material distribution plate 32 to rotate towards the material passage hole 2. The first material distribution plate 30 and the second material distribution plate 32 respectively extend into the lowermost blister tray 1 among a plurality of blister trays 1 and between the blister trays 1 adjacent to the blister tray 1.

[0059] S4. The output shaft of the power source 10 continues to extend, and the end of the blister tray 1 located at the bottommost side near the power source 10 falls from the first material support plate 13 and the second material support plate 14 to the bottom of the mounting base inside the material passage hole 2.

[0060] S5, the output shaft of the power source 10 extends to its maximum, the first swing arm 26 swings to the left and drives the first swing arm 26, the third material support plate 28 and the second swing arm 27 to move away from the power source 10. The end of the blister tray 1 located at the bottom away from the power source 10 falls from the third material support plate 28 to the bottom of the mounting base in the material passage hole 2. At this time, the blister tray 1 at the bottom is split and falls to the bottom of the mounting base.

[0061] After steps S6 and S5 are completed, the output shaft of the power source 10 is reset, the first cam drive 29 drives the first material distribution plate 30 to reset, the second cam drive 31 drives the second material distribution plate 32 to reset, the material distribution plate 16 is reset, the first material support plate 13, the second material support plate 14 and the third material support plate 28 support the remaining several blister trays 1, and then steps S2 to S5 are repeated.
