Description

Technical Field

[0001] The present invention relates to the technical field of cup pushing mechanisms, and in particular to an opposed-counting horizontal cup pushing mechanism. Background Art

[0002] The cup receiving table is one of the basic units of a plastic container surface printing machine system, mainly composed of a V-shaped conveyor belt, a counting cup pushing mechanism, and a tipping conveyor mechanism. Among them, the counting cup pushing mechanism is the core of the cup receiving table unit. When the number of passed cups reaches a preset number, the clamping jaws extend inwards to block the passage of the cups, and the upper cup pushing mechanism pushes the bunch of cups to the tipping place, and the tipping bucket flips to send the cups to the packer.

[0003] When the distance between the cup rims of the existing cup pushing mechanism is too small, the clamping jaws on both sides for blocking the passage of the cups cannot accurately insert into the cup rim gap, resulting in damage to the cups due to extrusion. At the same time, due to the upward cup pushing, one side of the cup is stressed, and the bunch of cups is too tightly sleeved, which will pull the cups blocked from passing, causing the subsequent cups to be unstable in posture and affecting the counting.

[0004] Therefore, it is necessary to design an opposed-counting horizontal cup pushing mechanism to solve the above problems. Summary of the Invention

[0005] To overcome the above disadvantages, the purpose of the present invention is to provide an opposed-counting horizontal cup pushing mechanism to ensure that the cups are accurately blocked, ensure uniform force on the cups during cup pushing, so that the subsequent cups are stably placed, and avoid affecting subsequent counting.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: an opposed-counting horizontal cup pushing mechanism, including a gantry support frame, a cup pushing assembly, and a conveying support frame for supporting and transferring the cups; the cup pushing assemblies are symmetrically arranged on both sides of the conveying support frame, the cup pushing assembly includes a cup pushing cylinder and a cup pushing claw located at the top of the piston rod of the cup pushing cylinder. When the piston rod of the cup pushing cylinder extends, the cup pushing claw can be inserted into the cup rim gap formed between adjacent cups from both sides of the cups. A cup blocking assembly and an opposed fiber optic sensor are correspondingly arranged below each cup pushing cylinder, and a cup pushing drive assembly capable of moving the cup pushing assembly back and forth along the conveying support frame is arranged on the gantry support frame.

[0007] Furthermore, the cup pushing drive assembly includes a telescopic cylinder fixedly arranged at the top of the gantry support frame through a cross beam. The telescopic cylinder is fixedly connected to the top of the cup pushing support through a connecting slider. The cup pushing support is arranged in an inverted U shape, and the cup pushing assembly is located on the cup pushing support. When the piston cylinder of the telescopic cylinder expands and contracts, it can drive the cup pushing support to move back and forth along the slide rail horizontally arranged on the cross beam. Through the expansion and contraction of the telescopic cylinder, a string of cups can be successively pushed one by one to the next working station. The two symmetrically arranged cup pushing assemblies are respectively located on the U-shaped legs of the cup pushing support, realizing cup pushing on both sides simultaneously and ensuring uniform force on the cups during cup pushing.

[0008] Furthermore, the cup pushing cylinder is connected to the cup pushing support through a cup pushing distance adjusting assembly. The cup pushing distance adjusting assembly includes a sliding block, an adjusting chute opened along the length direction of the sliding block, and a positioning protrusion located on the sliding block. A positioning chute matching the positioning protrusion is arranged on the cup pushing support, and a number of fixing holes for screws to pass through and lock the cup pushing cylinder and the sliding block are opened on the cup pushing support. When it is necessary to adjust the distance between the cup pushing cylinder and the cup, only need to unscrew the screw and push the sliding block forward or backward in the direction towards the cup. The positioning chute can provide guidance for the sliding of the sliding block. By adjusting the position of the cup pushing cylinder, the whole device can be applied to automatically push and count cups of different sizes, effectively improving the practicability.

[0009] Furthermore, the cup blocking assembly includes a cup blocking cylinder and a cup blocking claw located at the top of its piston rod. The cup blocking claw and the cup pushing claw are in the same vertical plane, and an inclined surface is provided at the front end of each claw. Ensure that the cup blocking claw and the cup pushing claw can be inserted into the same cup rim gap, and can also be accurately inserted even facing a smaller cup rim gap, effectively avoiding the phenomenon of cup extrusion damage.

[0010] Furthermore, it also includes a cup blocking distance adjusting assembly. The cup blocking distance adjusting assembly includes a guide frame horizontally passing through the conveying support frame, an adjusting screw located on the guide frame, and a connecting frame. Opposite threads are provided on the surface of the part of the adjusting screw away from the conveying support frame, and an adjusting handle is arranged at the top of the adjusting screw. The cup blocking cylinder is arranged on the connecting frame. By rotating the adjusting handle, the adjusting screw rotates, enabling the two symmetrically arranged cup blocking assemblies to move towards or away from each other, and simultaneously adjusting the distance between the cup blocking assemblies on both sides and the cups to meet the cup blocking requirements of cups of different sizes.

[0011] Further, guiding components are symmetrically arranged on the gantry support frame along the center line in its length direction. The guiding components include a number of adjusting rods and fixing handles for detachably fixing the adjusting rods on the gantry support frame. A strip-shaped groove for the fixing end of the fixing handle to pass through is formed along the length direction of the adjusting rod. The bottoms of the two symmetrically arranged adjusting rods are connected by a guiding rod. By loosening or tightening the fixing handle, the movable adjustment of the adjusting rod and its fixation to the gantry support frame are realized. The fixing handle is threadedly connected to the gantry support frame. The position of the adjusting rod is adjusted according to the size of different cups, so that the guiding components meet the guiding requirements of the cups and at the same time fix the forward direction of the cups, ensuring that the cups will not shift in position or fall off the conveying support during the conveying process.

[0012] Further, an arc-shaped surface adapted to the shape of the cup is provided on the surface of the conveying support, preventing the cup from shifting in position to both sides during movement and further fixing the forward direction of the cup.

[0013] Advantages of the present invention:

[0014] Through the mutual cooperation of the gantry support frame, the cup-pushing driving component, the cup-pushing component, the cup-blocking component, the opposed fiber optic sensors, and the conveying support in the present invention, when the piston rod of the cup-pushing cylinder extends to drive the cup-pushing claw to catch into the gap between the rims of two adjacent cups, when the cup-pushing driving component drives the cup-pushing component to move, the cup-pushing claw can push the cup forward from both sides of the cup, ensuring that the cup is evenly stressed when being pushed; when the cup-pushing cylinder works, the cup-blocking cylinder also drives the cup-blocking claw to catch into the above-mentioned gap between the rims, and the cup-blocking claw will not move forward. Therefore, when the front cup moves forward, the cup-blocking claw can separate the rear cup from the front cup, so that the rear cup will not follow the front cup to move, ensuring that the cup is accurately blocked, thereby ensuring the stable placement of the subsequent cups and avoiding affecting the counting of the opposed fiber optic sensors.

Detailed implementation manners

[0020] The following elaborates on the preferred embodiments of the present invention in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined.

[0021] See the appendix Figures 1 to 4 As shown, a through-beam counting horizontal push cup mechanism in this embodiment includes a gantry support frame 1, a push cup assembly 5, and a conveyor support 9 for supporting and transferring cups; the push cup assemblies 5 are symmetrically arranged on both sides of the conveyor support 9, and the push cup assemblies 5 can simultaneously push the cups forward from both sides of the cups, effectively ensuring uniform force on the cups when pushing the cups and avoiding affecting the subsequent placement posture of the cups;

[0022] The push cup assembly 5 includes a push cup cylinder 52 and a push cup claw 53 located at the top of the piston rod of the push cup cylinder 52. When the piston rod of the push cup cylinder 52 extends, the push cup claw 53 can be inserted into the cup rim gap formed between adjacent cups from both sides of the cup. A cup blocking assembly 7 and a through-beam fiber optic sensor 12 are correspondingly arranged below each push cup cylinder 52. A push cup drive assembly 3 capable of moving the push cup assembly 5 back and forth along the conveyor support 9 is arranged on the gantry support frame 1. The through-beam fiber optic sensor 12 is located directly below the cup blocking assembly 7 and between the first cup rim gaps, which can ensure that when pushing the cups, the cups that have been detected and counted are pushed away, while the cups that have not been detected are blocked by the cup blocking assembly 7; the through-beam fiber optic sensor 12 can irradiate the cup rim of the cup to form an intermittent signal. When the cup passes through, the fiber optic sensor can calculate the number of cups passing through by receiving the intermittent signal, realizing automatic push cup counting.

[0023] See the appendix Figure 1, the cup pushing drive assembly 3 includes a telescopic cylinder 31 fixedly arranged at the top of the gantry support frame 1 through a cross beam 2. The telescopic cylinder 31 is fixedly connected to the top of the cup pushing bracket 51 through a connecting slider 4. The cup pushing bracket 51 is arranged in an inverted U shape, and the cup pushing assembly 5 is located on the cup pushing bracket 51. When the piston cylinder of the telescopic cylinder 31 expands and contracts, it can drive the cup pushing bracket 51 to move back and forth along the slide rail 32 horizontally arranged on the cross beam 2. Through the expansion and contraction of the telescopic cylinder 31, a string of cups can be sequentially pushed one by one to the next working station. The two symmetrically arranged cup pushing assemblies 5 are respectively located on the U-shaped legs of the cup pushing bracket 51, realizing cup pushing on both sides simultaneously and ensuring uniform force on the cups during cup pushing.

[0024] See Appendix Figures 1 to 4 , the cup pushing cylinder 52 is connected to the cup pushing bracket 51 through a cup pushing distance adjustment assembly 6. The cup pushing distance adjustment assembly 6 includes a sliding block 61, an adjustment chute 64 opened along the length direction of the sliding block 61, and a positioning protrusion located on the sliding block 61. A positioning chute 63 matching the positioning protrusion is arranged on the cup pushing bracket 51, and a plurality of fixing holes 65 for screws to pass through and lock the cup pushing cylinder 52 and the sliding block 61 are opened on the cup pushing bracket 51. When it is necessary to adjust the distance between the cup pushing cylinder 52 and the cup, only need to unscrew the screw and push the sliding block 61 forward or backward in the direction towards the cup. The positioning chute 63 can provide guidance for the sliding of the sliding block 61. By adjusting the position of the cup pushing cylinder 52, the whole device is applicable to automatically push and count cups of different sizes, effectively improving the practicability.

[0025] See Appendix Figure 2 , the cup blocking assembly 7 includes a cup blocking cylinder 71 and a cup blocking claw 72 located at the top of its piston rod. The cup blocking claw 72 and the cup pushing claw 53 are in the same vertical plane, and an inclined surface 10 is provided at the front end of each claw. Ensure that the cup blocking claw 72 and the cup pushing claw 53 can be inserted into the same cup rim gap, and can also be accurately inserted even for a smaller cup rim gap, effectively avoiding the phenomenon of cup extrusion and damage.

[0026] See Appendix Figure 3 , it further includes a cup blocking distance adjustment assembly 8. The cup blocking distance adjustment assembly 8 includes a guide frame 82 horizontally passing through the conveying support frame 9, an adjustment screw 81 located on the guide frame 82, and a connecting frame 84. Opposite threads are provided on the surface of the part of the adjustment screw 81 away from the conveying support frame 9. An adjustment handle 83 is arranged at the top of the adjustment screw 81. The cup blocking cylinder 71 is arranged on the connecting frame 84. By rotating the adjustment handle 83, the adjustment screw 81 rotates, making the two symmetrically arranged cup blocking assemblies 7 move towards or away from each other, and at the same time adjusting the distance between the two side cup blocking assemblies 7 and the cup to meet the cup blocking requirements of cups of different sizes.

[0027] See the appendix Figure 1 and 3 On the gantry support frame 1, a guiding component 11 is symmetrically arranged along the central line in its length direction. The guiding component 11 includes a plurality of adjusting rods 113 and a fixing handle 111 for detachably fixing the adjusting rods 113 on the gantry support frame 1. Along the length direction of the adjusting rod 113, a strip-shaped groove 114 is formed for the fixing end of the fixing handle 111 to pass through. The bottoms of the two symmetrically arranged adjusting rods 113 are connected by a guiding rod 112. By loosening or tightening the fixing handle 111, the movable adjustment of the adjusting rod 113 and its fixation with the gantry support frame 1 are realized. The fixing handle 111 is threadedly connected with the gantry support frame 1. According to the size of different cups, the position of the adjusting rod 113 is adjusted so that the guiding component 11 meets the guiding requirements of the cups and at the same time fixes the advancing direction of the cups, ensuring that the cups will not shift in position or fall off the conveying support 9 during the conveying process.

[0028] See the appendix Figure 3 On the surface of the conveying support 9, an arc-shaped surface adapted to the shape of the cup is provided to prevent the cup from shifting in position to both sides during movement and further fix the advancing direction of the cup.

[0029] Working principle: When performing the cup pushing operation, the two cup pushing components 5 located on the cup pushing support 51 start to work. The piston rod of the cup pushing cylinder 52 extends, and the cup pushing claw 53 located at the top of the piston rod is pushed into the gap between the cup rims of two adjacent cups. Subsequently, the piston rod of the telescopic cylinder 31 extends to push the cup pushing support 51 towards the tipping bucket. During the movement of the cup, it is guided by the guiding rods 112 symmetrically arranged on both sides of the cup to ensure the stability of the cup's advancement.

[0030] Among them, when the cup pushing claw 53 is stuck into the gap between the cup rims of two adjacent cups, the cup blocking cylinder 71 also starts to work. Its piston rod extends to push the cup blocking claw 72 into the gap between the cup rims where the cup pushing claw 53 is located. When the cup pushing claw 53 pushes the cup forward, the cup blocking claw 72 effectively prevents the subsequent cups from moving forward, enabling the subsequent cups to be stably placed and avoiding affecting the subsequent counting.

[0031] Below the cup pushing claw 53, an opposed fiber optic sensor for counting is also installed. The opposed fiber optic sensor can irradiate the cup rim of the cup to form an intermittent signal. When the cup passes through, the fiber optic sensor can calculate the number of cups passing through by receiving the intermittent signal to achieve automatic cup pushing counting.

[0032] The above embodiments are only used to illustrate the technical concept and features of the present invention. The purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
