Description

Technical Field

[0001] The invention relates to a finished product arranging device for a molding machine, and more particularly to a finished product stacking mechanism for a molding machine capable of quickly stacking the finished products of the molding machine. Background Art

[0002] After the molding machine processes the plastic sheet into multiple finished products, the remaining part of the plastic sheet is usually connected to these finished products at multiple points, so that the remaining part of the plastic sheet can transport the finished products to the next workstation, allowing the cup rod to take the finished products away from the plastic sheet and complete the sorting and stacking.

[0003] The two stacking methods of stacking multiple finished products with different structures alternately or stacking the same finished product (with asymmetric structure) alternately at an angle are widely used in the process of arranging and stacking plastic products. However, the arranging and stacking equipment of the current molding machine can only stack the finished products at each position of the plastic sheet in the vertical direction, which is not only slow and inefficient, but also unable to complete the stacking of multiple finished products with different structures alternately or the stacking of the same finished product (with asymmetric structure) alternately at an angle. Summary of the invention

[0004] The purpose of the present invention is to provide a finished product stacking mechanism for a molding machine, which can quickly complete the stacking of finished products of the molding machine. The technical solution adopted is as follows:

[0005] A finished product stacking mechanism of a molding machine comprises a frame, characterized in that: at least one finished product sorting groove is provided on the frame, the finished product sorting groove opens downward and extends horizontally along the frame, a finished product outlet is provided at the right end of the finished product sorting groove, and at least two finished product stacking units are installed on the inner side wall of each finished product sorting groove; a finished product ejecting device and at least two finished product sorting devices are installed on the frame, the finished product ejecting device is located below all the finished product sorting grooves, the finished product ejecting device comprises at least two finished product ejecting groups, each finished product ejecting group has a plurality of finished product ejecting parts extending from bottom to top, each finished product sorting unit is respectively located at the top of all the finished product sorting grooves and each finished product sorting unit is sequentially distributed from left to right along the horizontal direction of the frame, and each finished product stacking unit is sequentially arranged from bottom to top along the vertical direction of the finished product sorting groove; the finished product ejecting group, the finished product sorting device, and the finished product stacking units on the inner side wall of each finished product sorting groove are the same in number and correspond one to one; each finished product stacking unit has a finished product stacking station that can complete the preset finished product stacking at its position.

[0006] In a preferred solution, the finished product stacking stations of each finished product stacking unit are distributed on the rack from low to high and from left to right according to the position height of the finished product stacking unit. That is to say, the finished product stacking unit with the lowest position height is located at the leftmost side of the rack. The higher the position height of the finished product stacking unit, the closer its position is to the right side of the rack. The finished product ejecting members of different finished product ejecting groups of the finished product ejecting device eject the finished products on the plastic sheet upward and eject the finished products into the finished product sorting tank from bottom to top. Until after the finished product moves above the finished product stacking unit corresponding to the finished product ejecting group where the finished product ejecting member is located, the finished product ejecting device drops back to its original position, and the finished product remains on this finished product stacking unit; then, the finished product sorting devices corresponding to each finished product ejecting group act in sequence from low to high according to the position height of the finished product stacking unit, and convey the finished products to the lower part of the adjacent next finished product stacking unit; continuously repeat the above two steps until the number of finished products in the finished product stack on the finished product stacking unit with the highest position reaches a preset value, and the finished product sorting device corresponding to the finished product stacking unit with the highest position pushes out this finished product stack from the finished product outlet.

[0007] In a preferred solution, all the finished product sorting tanks form a finished product sorting tank group rack. The finished product sorting tank group rack includes two mutually parallel positioning rods and multiple side wall plates. The two ends of each side wall plate are respectively installed on the two positioning rods to form a finished product sorting tank group rack that can be quickly assembled and disassembled. This finished product sorting tank group rack is installed on the rack, and a finished product sorting tank is formed between any two adjacent side wall plates. Adopting the structure of the finished product sorting tank group rack makes the finished product sorting tank convenient for manufacturing, installation, disassembly and maintenance.

[0008] In a more preferred solution, two active hanging grooves are respectively provided on the two positioning rods, and two positioning grooves are installed on the rack. The two active hanging grooves are respectively inserted into the two positioning grooves and fixed on the positioning grooves.

[0009] In a more preferred solution, all the side wall plates are parallel to each other.

[0010] In a better solution, each finished product stacking unit includes two elastic finished product supporting groove pieces. The bottom ends of the two elastic finished product supporting groove pieces are respectively installed on the inner side walls of the two side wall plates of the finished product sorting groove, and the two elastic finished product supporting groove pieces respectively extend upward and toward the middle of the finished product sorting groove. In this way, when the finished product rises from bottom to top under the lifting force of the finished product ejector, the finished product extrudes the two elastic finished product supporting groove pieces outward, forcing the two elastic finished product supporting groove pieces to deform and close to the inner side walls of the two side wall plates to make way for the finished product. Until the finished product completely crosses the two elastic finished product supporting groove pieces, the two elastic finished product supporting groove pieces return to their original positions after losing the pressure of the finished product. When the finished product ejector descends and leaves the finished product sorting groove, the edge of the finished product falls on the two elastic finished product supporting groove pieces, and the two elastic finished product supporting groove pieces can provide sufficient support for the finished product upward. In fact, the finished product stacking unit composed of the two elastic finished product supporting groove pieces is a limiting and supporting mechanism that only allows the finished product to pass unidirectionally from bottom to top.

[0011] In a better solution, the finished product ejecting device further includes a support seat and a lifting device. The lifting device is installed at the bottom of the frame, the support seat is installed on the lifting device, and each finished product ejecting group is respectively installed on the top surface of the support seat.

[0012] In a better solution, the lifting device is a first air cylinder.

[0013] In a better solution, the finished product sorting device includes a second air cylinder and a toggling frame. The second air cylinder is installed at the top of the frame, the toggling frame is installed on the second air cylinder, the toggling frame has at least one toggle rod, the number of the toggle rods is the same as that of the finished product sorting grooves and they correspond one by one, and each toggle rod is inserted into the corresponding finished product sorting groove from top to bottom.

[0014] The beneficial effect of the present invention compared with the prior art is that since the finished product sorting groove is provided with at least two finished product stacking units, and the finished product stacking stations of each finished product stacking unit are distributed from low to high and from left to right on the frame according to the position height of the finished product stacking unit, the same or different finished products can be stacked alternately into a finished product stack in sequence. It can not only greatly improve the work efficiency, but also realize the alternate stacking of finished products with different structures, or the stacking of the same finished product (asymmetric structure) after being alternately staggered by an angle, meeting the market demand.

[0023] Embodiment 1

[0024] As Figure 1-8 shown, the finished product stacking mechanism in this embodiment includes a frame 1, on which a finished product sorting tank group frame 2 is installed. The finished product sorting tank group frame 2 includes two parallel positioning rods 201 and four side wall plates 202. The two ends of each side wall plate 202 are respectively installed on the two positioning rods 201 to form a finished product sorting tank group frame 2 that can be quickly assembled and disassembled. A finished product sorting tank 204 is formed between any two adjacent side wall plates 202 of the finished product sorting tank group frame 2. Two active hanging grooves 203 are respectively provided on the two positioning rods 201, and two positioning grooves 101 are installed on the frame 1. The two active hanging grooves 203 are respectively inserted into the two positioning grooves 101 and fixed on the positioning grooves 101. With the structure of the finished product sorting tank group frame 2, the finished product sorting tank 204 is convenient for manufacturing, installation, disassembly and maintenance.

[0025] The finished product sorting tank group frame 2 is provided with two finished product sorting tanks 204. Each finished product sorting tank 204 opens downward and extends horizontally along the frame 1. A finished product outlet is opened at the right end of the finished product sorting tank 204. Two finished product stacking units 3 are installed on the inner side wall of each finished product sorting tank 204.

[0026] A finished product ejection device 4 and two finished product sorting devices 5 are installed on the frame 1. The finished product ejection device 4 is located below all the finished product sorting grooves 204. The finished product ejection device 4 includes a support base 401, a lifting device, and two finished product ejection groups 403. The lifting device is installed at the bottom of the frame 1, the support base 401 is installed on the lifting device, and each finished product ejection group 403 is respectively installed on the top surface of the support base 401. The lifting device is a first cylinder 402.

[0027] Each finished product ejection group 403 has three finished product ejection members 4031 extending upward from the bottom. Each finished product sorting unit is located at the top of all the finished product sorting grooves 204, and each finished product sorting unit is arranged horizontally along the frame 1 from left to right in sequence. Each finished product stacking unit 3 is arranged vertically along the finished product sorting groove 204 from bottom to top in sequence. In this embodiment, the top end of the finished product ejection member 4031 is designed to have the same shape as the finished product for better lifting, as Figure 6 shown. In fact, the finished product ejection member 4031 can also be designed as a platform to adapt to different finished products.

[0028] The number of the finished product ejection groups 403, the finished product sorting devices 5, and the finished product stacking units 3 on the inner side walls of each finished product sorting groove 204 is the same and they correspond one by one, all being two; each finished product stacking unit 3 respectively has a finished product stacking station where a preset finished product stacking can be completed at its position.

[0029] The finished product stacking stations of each finished product stacking unit 3 are distributed on the frame 1 from low to high and from left to right according to the position height of the finished product stacking unit 3. That is to say, the finished product stacking unit 3 with the lowest position height is located at the leftmost side of the frame 1, and the higher the position height of the finished product stacking unit 3, the closer its position is to the right side of the frame 1.

[0030] All the side wall plates 202 are parallel to each other.

[0031] Each finished product stacking unit 3 includes two elastic finished product support groove pieces 301. The bottoms of the two elastic finished product support groove pieces 301 are respectively installed on the inner side walls of the two side wall plates 202 of the finished product sorting groove 204, and the two elastic finished product support groove pieces 301 respectively extend upward above the middle of the finished product sorting groove 204. In this way, when the finished product rises from bottom to top under the lifting force of the finished product ejecting member 4031, the finished product extrudes the two elastic finished product support groove pieces 301 outward, forcing the two elastic finished product support groove pieces 301 to deform and close to the inner side walls of the two side wall plates 202 to make way for the finished product. Until the finished product completely passes over the two elastic finished product support groove pieces 301, the two elastic finished product support groove pieces 301 return to their original positions after losing the pressure of the finished product. When the finished product ejecting member 4031 descends and leaves the finished product sorting groove 204, the edge of the finished product falls on the two elastic finished product support groove pieces 301, and the two elastic finished product support groove pieces 301 can provide sufficient support for the finished product upward. In fact, the finished product stacking unit 3 composed of the two elastic finished product support groove pieces 301 is a limiting and supporting mechanism that only allows the finished product to pass unidirectionally from bottom to top.

[0032] The finished product sorting device 5 includes a second air cylinder 501 and a toggling frame 502. The second air cylinder 501 is installed at the top of the frame 1, and the toggling frame 502 is installed on the second air cylinder 501. The toggling frame 502 has two toggling rods 5021. The number of the toggling rods 5021 is the same as that of the finished product sorting grooves 204 and they correspond one by one. Each toggling rod 5021 is respectively inserted into the corresponding finished product sorting groove 204 from top to bottom. As Figure 4 shown, it is the toggling frame 502 on the left side. The toggling rod 5021 of this toggling frame 502 is longer because it is used to toggle the finished product on the finished product stacking unit 3 below. As Figure 5 shown, it is the toggling frame 502 on the right side. The toggling rod 5021 of this toggling frame 502 is shorter because it is used to toggle the finished product on the finished product stacking unit 3 above.

[0033] The following Figure 1-8 introduces the working process:

[0034] 1. All the finished product ejecting members 4031 of the two different finished product ejecting groups 403 of the finished product ejecting device 4 eject the 4 finished products 6 on the plastic sheet (2 left finished products 6 and 2 right finished products 6 are arranged oppositely, that is, in opposite directions, as Figure 6 shown) upward and eject the finished products 6 from bottom to top into the finished product sorting groove 204. Until the finished products 6 move above the finished product stacking unit 3 corresponding to the finished product ejecting group 403 where the finished product ejecting member 4031 is located, the finished product ejecting device 4 returns to its original position, and the finished products 6 remain on the finished product stacking unit 3;

[0035] 2. The finished product sorting device 5 corresponding to each finished product ejection group 403 operates in sequence from the lowest to the highest height according to the position of the finished product stacking unit 3, conveys the finished product 6 to the lower part of the next adjacent finished product stacking unit 3 on the right, and then repeats step 1, so that the finished product 6 ejected up next time at the finished product stacking station on the right is stacked with the finished product 6 staying below the finished product stacking station and rises above the finished product stacking unit 3 and is stacked with the finished product 6 above (that is to say, two finished products 6 are stacked with the finished product 6 above at one time);

[0036] 3. When the number of finished products 6 in the finished product stack 7 on the finished product stacking unit 3 with the highest position reaches the preset value, the finished product sorting device 5 corresponding to the finished product stacking unit 3 with the highest position ejects the finished product stack 7 from the finished product outlet.

[0037] That is to say, when the first finished product ejection device 4 operates, there is one finished product 6 on the finished product stacking station on the left and also one finished product 6 on the finished product stacking station on the right; after the finished product sorting device 5 on the left moves the finished product 6 to the lower part of the finished product stacking station on the right, the second finished product ejection device 4 operates. There is still only one finished product 6 on the finished product stacking station on the left, while there are 2 finished products 6 on the finished product stacking station on the right. This cycle continues, and the rapid stacking of the finished product 6 is completed on the finished product stacking station on the right, and the directions of two adjacent finished products 6 are opposite. As Figure 7 、 8 shown, the finished products 6 in the finished product stack 7 are stacked alternately in sequence. For easy distinction, the bottom surface of the finished product 6 on the left is engraved with A, and the bottom surface of the finished product 6 on the right is engraved with B for distinction.
