The transmission belt of the embodiment is driven to run by a chain transmission mechanism, the chain transmission mechanism comprises a front chain wheel 14, a middle chain wheel 15 and a rear chain wheel 16, the middle chain wheel 15 can be arranged between the front chain wheel 14 and the rear chain wheel 16 or/and on the frame section 6, the front chain wheel 14, the middle chain wheel 15 and the rear chain wheel 16 are connected in a transmission way through a chain 17, and the transmission belt 1 above the front chain wheel 14 and the rear chain wheel 16 is horizontally transmitted. The chain conveying mechanism drives the speed reducer 190 to run by virtue of the driving motor 19, the driving motor is arranged on the frame profile 6, the driving motor 19 is in conveying connection with the speed reducer 190, the speed reducer 190 drives the front chain wheel 14 to rotate by conveying the connection of the conveying chain and the front chain wheel 14, and then the conveying belt 1 on the whole chain 17 is driven to move.
The conveyor belt and the visual inspection device of this embodiment are both installed on the frame profile, as shown in fig. 1 and 2, two cams 72 that do not run synchronously are further provided at the bottom of the bottom plate 71 of the upper bin 7 of this embodiment, and the cams 72 are connected to the cam motor through a cam shaft 73 to shake the bottom of the upper bin up and down, so that the ice cream bars in the upper bin are taken away by the conveyor belt uniformly and rapidly. The conveyor belt 1 conveys the ice cream sticks which are subjected to primary processing in the feeding bin 7 to the position below the visual detection equipment 2 for detection. The bottom of the upper bin 7 shakes the ice cream bars in the upper bin 7 up and down by the rotation of two unsynchronized cams 72, so that the ice cream bars can be rapidly conveyed. Visual detection equipment on the conveyor belt and a picking mechanism are matched with each other to remove unqualified ice cream sticks on the conveyor belt, so that damage to consumers caused by producing unqualified ice cream sticks is avoided, and the running speed of the whole machine can meet the requirements of users more than that of the existing equipment on the market.
As shown in fig. 3 and fig. 4, the picking mechanism 3 includes a picking motor 31 and a plurality of wheel plates 32 uniformly arranged on a motor shaft of the picking motor 31, wherein the wheel plates 32 are uniformly arranged along a radial direction of the motor shaft and are located in a same rotation area; when the material removing motor 31 rotates once, one wheel plate 32 passes over one side of the conveyor belt 1 in the rotating process, and simultaneously, the ice cream bar at the position is removed to the other side of the conveyor belt 1. The material rejecting mechanism adopts a structure that the motor is matched with the wheel plate, so that the defective ice cream stick can be rejected once per rotation of the motor, the defective ice cream stick can be effectively matched with the visual detection device, and the operation efficiency is greatly improved. In practice, the motor shaft of the material picking motor is sleeved and fixed with a wheel shaft, and the wheel plates are all fixed on the wheel shaft. When the motor shaft of the material removing motor rotates once, the wheel plate removes the corresponding ice cream stick on the conveyor belt and is positioned above one side of the conveyor belt.
As shown in fig. 3 and fig. 4, the number of the wheel plates 32 on the motor shaft of the picking motor 31 may be set according to the operation mode of the motor, that is, the angle of each rotation of the motor, where in this embodiment, four wheel plates 32 are preferred, and two adjacent wheel plates 32 are perpendicular to each other. The four wheel plates are easy to control, and can be used for removing an ice cream stick defective product every 90 degrees, when the visual detection equipment detects that the defective product exists, the motor operation of the material removing mechanism can be controlled, and because the visual detection equipment and the material removing mechanism have a certain distance, the visual detection equipment can accurately take the running time of the motor to remove materials, and the four wheel plates are arranged, so that the rotation distance between the two wheel plates is more suitable for control, the installation and control of the force of removing the ice cream stick defective product every time, and the time sequence of the control of the wheel plates and the visual detection device are matched. When the wheel plates are not driven, the end parts of the two lower wheel plates are positioned on the same horizontal plane, and the end parts of the two upper wheel plates are positioned on the same horizontal plane, so that after the motor shaft of the picking motor rotates each time, the position of each wheel plate is not changed relative to the conveying belt, and the position of the wheel plate does not need to be regulated again each time of picking.
In another specific implementation manner of this embodiment, as shown in fig. 3 and fig. 4, the ice cream stick defective product selecting machine further includes a collecting cylinder 4 for collecting the removed ice cream sticks, where the collecting cylinder 4 is disposed on the other side of the conveyor belt 1, and a collecting opening 41 of the collecting cylinder 4 is disposed opposite to the picking mechanism 3. The collecting barrels are arranged at the opposite positions of the picking mechanism, so that the defective ice cream sticks rejected by the picking mechanism can be collected, and the problem that the defective ice cream sticks are difficult to collect is avoided.
As shown in fig. 3, a preferred solution of the collecting cylinder 4 is to arrange the collecting cylinder 4 in an arc shape, one end of the collecting cylinder is fixed on the ground, the other end is provided with a collecting port 41, and the collecting port 41 is arranged opposite to the wheel plate 32 of the picking mechanism 3; every time the wheel plate 32 rejects an ice cream bar defective product, the ice cream bar defective product is just dialed into the collecting cylinder 4 by the wheel plate 32, and the appearance of the collecting cylinder 4 is set to be arc-shaped, so that on one hand, more ice cream bar defective products are contained, and on the other hand, the ice cream bar defective products which are driven into the collecting cylinder are not easy to fall out.
The ice cream stick defective product selector of the embodiment firstly transmits the ice cream sticks in the ice cream stick feeding bin to the lower part of the visual detection equipment through the conveyor belt for image detection and analysis; the visual detection equipment judges whether each detected ice cream stick is defective or not, and when the existence of the ice cream stick defective products is detected, the visual detection equipment sends a control command to the material picking motor, and in fact, when the ice cream stick defective products are conveyed to the position of the material picking mechanism by the conveyor belt, the control command is sent to the material picking motor, and the material picking motor immediately drives the wheel plate to pick materials; or the control command is sent to the material removing motor immediately, and the material removing motor delays until the ice cream bar defective products are conveyed to the position of the material removing mechanism by the conveyor belt, and the wheel plate is driven to rotate by a preset angle to remove the ice cream bar defective products.
Example 2
In addition to the technical features of the embodiment 1, as shown in fig. 1 and 2, the ice cream stick defective product selecting machine of the embodiment is provided with two groups of detection picking mechanisms, which are arranged in front and back along the conveying direction of the conveyor belt 1; the turnover mechanism 5 is arranged below the conveyor belt 1, and the turnover mechanism 5 is positioned between two groups of detection picking mechanisms and turns over ice cream sticks on the conveyor belt passing through the detection picking mechanisms in sequence. By arranging two groups of detection and picking mechanisms and arranging a turn-over mechanism between the two groups of detection and picking mechanisms, two sides of the ice cream stick can be detected, so that the ice cream stick can be detected more comprehensively and has higher detection precision.
As shown in fig. 5, the turnover mechanism 5 includes a turnover wheel 51 and a turnover motor 52, wherein a plurality of material clamping openings 511 uniformly distributed along the circumferential direction of the turnover wheel 51 are formed on the peripheral outer edge of the turnover wheel 51, and a part of the turnover wheel 51 is positioned above the conveyor belt 1; the driving shaft of the turnover motor 52 is fixedly connected with the turnover wheel 51 coaxially and drives the turnover wheel 51 to rotate clockwise, so that the part of the turnover wheel 51 above the driving belt 1 picks up ice cream sticks on the rear side one by one through the material clamping openings 511 and turns 180 degrees and then sequentially places the ice cream sticks on the front side of the driving belt 1. The setting of the material clamping opening on the turn-over wheel can accurately pick up ice cream sticks which are transported each time one by one, and the ice cream sticks are placed on the conveyor belt after being turned over by 180 degrees. The number of the turnover wheels can be 1 or more, and the embodiment can preferably adopt two groups of turnover wheels, each group has two turnover wheels, and the two groups of turnover wheels are respectively and coaxially fixed at positions of the shaft sleeve close to two ends. The direction of the straight arrow in fig. 5 is the conveying direction of the conveyor belt, and the direction of the curved arrow is the rotation direction of the turn-up wheel 51.
As shown in fig. 5, two ends of the material clamping opening 511 extend to two end surfaces of the turnover wheel 51, the width of the material clamping opening 511 is larger than the thickness of the ice cream stick, and the depth of the material clamping opening 511 is smaller than or equal to the width of the ice cream stick, so that the ice cream stick is easier to be placed on the conveyor belt 1 from the material clamping opening 511 when the ice cream stick is easier to be picked up by the material clamping opening 511.
In this embodiment, the conveyor belt 1 is provided with a plurality of feeding slots 12 with two open ends and perpendicular to the conveying direction of the conveyor belt 1; in practice, the upper surface of the conveyor belt 1 is provided with a plurality of U-shaped blocks 11 arranged side by side, and the feeding groove 12 is formed in the U-shaped blocks 11. When the turnover wheel 51 rotates one material clamping opening 511 to a position parallel to the conveying direction of the conveying belt 1 and with the opening arranged backwards, the conveying belt 1 synchronously moves backwards for a feeding distance (one feeding distance is actually the width of one U-shaped block 11 along the conveying direction), and ice cream bars in a feeding groove 12 at the rear side of the turnover wheel 51 are picked up and clamped in the material clamping opening 511 of the turnover wheel 51, so that the feeding groove 12 passing through the turnover wheel 51 is empty; after the turnover wheel 51 turns over the ice cream stick in the material clamping opening 511 by 180 degrees, the ice cream stick in the material clamping opening 511 sequentially falls into other empty slots corresponding to the front side of the turnover wheel 51, so that the problem that empty slots or incomplete pick-up occurs after turnover is avoided.
In addition, in order to make the process of picking up the ice cream stick by the turnover wheel more accurate, as shown in fig. 2 and 5, a connecting shaft 512 is arranged in the middle of the turnover wheel 51, and a driving shaft of the turnover motor 52 is fixedly connected with the connecting shaft 512 coaxially; the axis of the connecting shaft 512 is perpendicular to the conveying direction of the conveyor belt 1, the central line of the connecting shaft 512 is positioned below the conveyor belt 1, and the extension line of the central line of the material clamping opening 511 is tangential to the connecting shaft 512. The diameter of the connecting shaft 512 needs to be set according to the size and actual needs of the turnover wheel 51, most of the connecting shaft 512 is located below the conveyor belt 1, and in the rotation process of the turnover wheel 51, the material clamping opening 511 for picking up ice cream bars and putting down ice cream bars can be generally on the same horizontal plane with the bottom surface of the material feeding groove 12 of the conveyor belt 1, so that the problem of material clamping between the conveyor belt 1 and the turnover wheel 51 is not easy to occur. Of course, the turn-over wheel 51 and the conveyor belt 1 in this embodiment run synchronously, so as to ensure that the feeding groove 12 of the conveyor belt 1 located at one side of the turn-over wheel 51 is an empty groove, and achieve the purpose of continuous turn-over in sequence.
In a preferred embodiment of the turnover wheel of this embodiment, as shown in fig. 5, a circle of triangular tooth edges 513 are further formed on the peripheral outer edge of the turnover wheel 51, and one material clamping opening 511 is formed between two adjacent tooth edges 513. The tooth edges are arranged, so that the ice cream sticks in the material clamping opening can slide out smoothly, and the situation that the material clamping is caused by the fact that the turnover wheel continuously drives the ice cream sticks to rotate when the conveyer belt does not convey the turned ice cream sticks away is avoided. The tooth edge of the triangle structure enables the exterior of the material delivery opening to be in a horn-shaped open structure, and the peripheral side of the tooth edge is in a cambered surface structure.
As shown in fig. 2, 3 and 4, the conveyor belt 1 is two conveyor belts arranged in parallel and synchronously operated, and a turnover gap 13 is reserved between the two conveyor belts 1; the ice cream stick is vertically erected on the two conveyor belts 1, the middle part of the ice cream stick is positioned in the turnover gap 13, and the turnover wheel 51 is installed in the turnover gap 13 between the two conveyor belts 1. Two parallel arranged conveyor belts 1 are arranged, the turnover wheels 51 are arranged between the two conveyor belts 1, the middle part of the ice cream stick is used for picking up the turnover wheels 51, the two ends of the ice cream stick are used for conveying the conveyor belts 1, the conveyor belts 1 and the turnover wheels 51 are mutually noninterfere and are mutually matched, and the picking up and conveying process is more stable and reliable.
