Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging equipment technology, specifically to an online sampling and weighing method for a double-row bottle conveyor belt. Background Technology

[0002] Existing online sampling and weighing devices for bottle conveyor belts are generally single-row conveyor belts for filling, consisting of a conveyor belt and weighing mechanism along one row, with a filling mechanism mounted on the conveyor belt. This single-row filling process results in low production efficiency. Currently, to improve efficiency, multi-row online sampling and weighing devices for bottle conveyor belts are often installed. However, each conveyor belt has its own weighing mechanism, which occupies a large area and is costly. If a double-row conveyor belt is used to share a single weighing mechanism, a shortage of bottles on one conveyor belt can cause bottle sequence disorder, making proper sampling impossible. This makes it difficult to match the weighed bottles with the filling needles of the filling mechanism. Consequently, if the bottle filling volume is insufficient, it becomes difficult to find the corresponding filling pump connected to the filling needle. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an online sampling and weighing method for a double-row bottle conveyor belt that meets the normal sampling requirements of the online sampling and weighing mechanism, can match the weighed bottles with the filling needles of the filling mechanism, and can accurately find the filling pump corresponding to the bottles with substandard filling volume.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A method for online sampling and weighing of bottles using a double-row bottle conveyor belt is disclosed. The double-row bottle conveyor belt online sampling and weighing device includes an online sampling and weighing mechanism. The inlet side of the online sampling and weighing mechanism is equipped with a bottle inlet detection sensor and a bottle conveyor belt. The inlet side of the bottle conveyor belt has two parallel conveying tracks, each with a corresponding filling mechanism. Each filling mechanism has N filling needles for batch filling operations. The outlet side of the two parallel conveying tracks is equipped with an interlocking bottle release mechanism to control the entry of bottles from a single conveying track into the bottle conveyor belt. The method for online sampling and weighing of bottles using a double-row bottle conveyor belt includes the following steps:

[0006] S1, initialize the bottle release count to 0, and the pump sampling array is empty;

[0007] S2, the bottle feeding operation of the bottle feeding mechanism is controlled by the number of bottle feedings. If the number of bottle feedings is less than the number of bottle groups M that can be placed on the bottle conveyor belt, and one of the two parallel conveyor tracks has completed the batch filling operation, then the bottle feeding mechanism controls the group of bottles on the first conveyor track to enter the bottle conveyor belt, increments the number of bottle feedings by 1, and sends the information of that group of bottles to the pump sampling array. If the number of bottle feedings after incrementing by 1 is equal to the number of bottle groups M that can be placed on the bottle conveyor belt, then the information of the bottles in the pump sampling array is... The value is assigned to the transfer sampling array; at the same time, the bottle entry signal of the online sampling and weighing mechanism is detected by the bottle entry detection sensor. If the bottle entry signal is detected, the cumulative number of bottles entered is incremented by 1. The information of the bottle currently sent to the online sampling and weighing mechanism is determined based on the cumulative number of bottles entered and the transfer sampling array. The bottle is sampled and weighed, and the bottle information and the sampling and weighing results are associated and output. If the cumulative number of bottles entered is equal to the number of bottles N in a set, the number of bottle releases is decremented by 1 and the cumulative number of bottles entered is cleared to zero.

[0008] As a further improvement to the above technical solution:

[0009] The size of the pump sampling array is M×N, and sending the information of the group of bottles into the pump sampling array means shifting the original data in the pump sampling array to the right by N positions, and then sending the information of the group of bottles into the first N positions of the pump sampling array, so that the information of each group of bottles recorded in the pump sampling array is sorted according to the time of addition.

[0010] The number of bottle groups M that can be placed on the bottle conveyor belt is 3.

[0011] The number of bottles N in the group is 12.

[0012] When determining the information of the bottle currently being fed into the online sampling and weighing mechanism based on the cumulative number of bottles fed into the mechanism and the transfer sampling array, the element index of the information of the bottle currently being fed into the online sampling and weighing mechanism in the transfer sampling array is [M×N-cumulative number of bottles fed into the mechanism].

[0013] After determining the information of the bottle currently being fed into the online sampling and weighing mechanism, the process includes using a sampling array to record the information of the bottle currently being fed into the online sampling and weighing mechanism.

[0014] The method of using a sampling array to record the information of the bottles currently being fed into the online sampling and weighing mechanism includes shifting the data in the sampling array one position to the right, and then inserting the information of the bottles currently being fed into the online sampling and weighing mechanism into the first position in the sampling array.

[0015] The online sampling and weighing mechanism is connected to the bottle conveyor belt by an inlet auger and an outlet deflector, and the inlet detection sensor is located at the inlet of the inlet auger.

[0016] Compared with the prior art, the advantages of the present invention are as follows:

[0017] The online sampling and weighing method of the double-row bottle conveyor belt of the present invention adopts a shared online sampling and weighing mechanism for two conveyor tracks. The bottle placement mechanism controls a group of bottles on the first conveyor track to enter the bottle conveyor belt 2, so that the bottles on the two conveyor tracks enter the conveyor belt in the order of completion of filling. The number of bottle placements is incremented and the information of the group of bottles is sent to the pump sampling array. If the number of bottle placements after incrementing by 1 is equal to the number of bottle groups M that can be placed on the bottle conveyor belt, the information of the bottles in the pump sampling array is assigned to the transfer sampling array. That is, after the bottle conveyor belt is filled with the number of bottle groups M, the information of the bottles in the pump sampling array is assigned to the transfer sampling array, so that the transfer sampling array has the information of all bottles on the bottle conveyor belt. At the same time, the online sampling weighing is detected by the bottle entry detection sensor. If a bottle-in signal is detected by the weighing mechanism, the cumulative number of bottles entered is incremented by 1. Based on the cumulative number of bottles entered and the intermediate sampling array, the information of the bottles currently being fed into the online sampling and weighing mechanism is determined. The bottles are then sampled and weighed, and the bottle information and the sampling and weighing results are correlated and output. In this way, the information of the bottles currently being fed into the online sampling and weighing mechanism is determined routinely based on the cumulative number of bottles entered and the intermediate sampling array, so that each bottle entering the online sampling and weighing mechanism can find the pump to be filled according to the information, which meets the normal sampling requirements of the online sampling and weighing mechanism 1. This allows the weighed bottles to be matched with the filling needles of the filling mechanism. If the bottle filling volume is not up to standard, the filling pump connected to the corresponding filling needle can be accurately located. Attached Figure Description

[0025] Figure 1 This paper illustrates an embodiment of the online sampling and weighing method for a double-row bottle conveyor belt according to the present invention. This embodiment employs a double-row bottle conveyor belt online sampling and weighing device, which includes an online sampling and weighing mechanism 1. The inlet side of the online sampling and weighing mechanism 1 is equipped with a bottle inlet detection sensor 13 and a bottle conveyor belt 2. The inlet side of the bottle conveyor belt 2 has two parallel conveying tracks 3, each with a corresponding filling mechanism 4. The filling mechanism 4 has N filling needles for batch filling operations. The outlet side of the two parallel conveying tracks 3 is equipped with an interlocking bottle release mechanism 5 to control the entry of bottles from a single conveying track 3 into the bottle conveyor belt 2. The online sampling and weighing method for a double-row bottle conveyor belt includes the following steps:

[0026] S1, initialize the bottle release count to 0, and the pump sampling array is empty;

[0027] S2, the bottle-dispensing operation of the bottle-dispensing mechanism 5 is controlled by the number of bottle dispensing cycles. If the number of bottle dispensing cycles is less than the number of bottle groups M that can be placed on the bottle conveyor belt 2, and one of the two parallel conveyor tracks 3 has completed the batch filling operation, then the bottle-dispensing mechanism 5 controls a group of bottles on the first conveyor track 3 to enter the bottle conveyor belt 2, increments the number of bottle dispensing cycles by 1, and sends the information of that group of bottles (the group of bottles being dispensed) to the pump sampling array. If the number of bottle dispensing cycles after incrementing by 1 is equal to the number of bottle groups M that can be placed on the bottle conveyor belt 2, then the information of the bottles in the pump sampling array is assigned to the middle... The sampling array is transferred; at the same time, the bottle entry signal of the online sampling and weighing mechanism 1 is detected by the bottle entry detection sensor 13. If the bottle entry signal is detected, the cumulative number of bottles entered is incremented by 1. The information of the bottle currently sent to the online sampling and weighing mechanism 1 is determined according to the cumulative number of bottles entered and the intermediate sampling array. The bottle sent to the online sampling and weighing mechanism 1 is sampled and weighed, and the bottle information and the sampling and weighing results are associated and output. If the cumulative number of bottles entered (the cumulative number of bottles entered by the online sampling and weighing mechanism 1) is equal to the number of bottles N in a set of bottles, the number of bottle releases is decremented by 1 and the cumulative number of bottles entered is cleared to zero.

[0028] This online sampling and weighing method using a double-column bottle conveyor belt employs a shared online sampling and weighing mechanism 1 across two conveyor tracks 3. The bottle placement mechanism 5 controls a group of bottles (multiple groups can be accommodated on one of the first conveyor tracks 3 to complete batch filling) to enter the bottle conveyor belt 2. This ensures that bottles from both conveyor tracks 3 enter the conveyor belt 2 in the order they were filled. The bottle placement count is incremented by 1, and the information of that group of bottles (such as bottle number, pump number, and / or a signal indicating the bottle number corresponds to the pump number) is sent to the pump sampling array. If the incremented bottle placement count equals the number of bottle groups M that can be placed on the conveyor belt 2, the bottle information from the pump sampling array is assigned to the intermediate sampling array. That is, after the conveyor belt 2 is filled with the number M of bottle groups, the bottle information from the pump sampling array is assigned to the intermediate sampling array, ensuring that the intermediate sampling array contains information about all bottles on the conveyor belt 2. The bottle-in signal of the online sampling and weighing mechanism 1 is detected by the bottle-in detection sensor 13. If the bottle-in signal is detected, the cumulative number of bottles entered is incremented by 1. The information of the bottle currently sent to the online sampling and weighing mechanism 1 is determined according to the cumulative number of bottles entered and the transfer sampling array. The bottle is sampled and weighed, and the bottle information and the sampling and weighing results are associated and output. In this way, the information of the bottle currently sent to the online sampling and weighing mechanism 1 is determined according to the cumulative number of bottles entered and the transfer sampling array, so that each bottle entering the online sampling and weighing mechanism 1 can find the pump to fill it according to the information (such as the information that the bottle number corresponds to the pump number), which satisfies the normal sampling of the online sampling and weighing mechanism 1. Thus, the weighed bottle can be matched with the filling needle of the filling mechanism. If the bottle filling volume is not up to standard, the filling pump connected to the corresponding filling needle can be accurately found.

[0029] Furthermore, in this embodiment, the size of the pump sampling array is M×N, and sending the information of the group of bottles into the pump sampling array means shifting the original data in the pump sampling array to the right by N positions, and then sending the information of the group of bottles into the first N positions of the pump sampling array, so that the information of each group of bottles recorded in the pump sampling array is sorted according to the time of addition.

[0030] Furthermore, in this embodiment, the number of bottle groups M that can be placed on the bottle conveyor belt 2 is 3.

[0031] Furthermore, in this embodiment, the number N of a group of bottles is 12.

[0032] Furthermore, in this embodiment, when determining the information of the bottle currently being fed into the online sampling and weighing mechanism 1 based on the cumulative number of bottles fed into the mechanism and the transit sampling array, the element index of the information of the bottle currently being fed into the online sampling and weighing mechanism 1 in the transit sampling array is [M×N-cumulative number of bottles fed into the mechanism].

[0033] Furthermore, in this embodiment, after determining the information of the bottle currently being fed into the online sampling and weighing mechanism 1, the method includes using a sampling array to record the information of the bottle currently being fed into the online sampling and weighing mechanism 1.

[0034] Furthermore, in this embodiment, using a sampling array to record the information of the bottle currently being fed into the online sampling and weighing mechanism 1 includes shifting the data in the sampling array one position to the right, and then inserting the information of the bottle currently being fed into the online sampling and weighing mechanism 1 into the first position in the sampling array.

[0035] Furthermore, in this embodiment, an inlet auger 11 and an outlet wheel 12 are provided between the online sampling and weighing mechanism 1 and the bottle conveyor belt 2, and the inlet detection sensor 13 is located at the inlet of the inlet auger 11. At this time, the specific process of S2 is as follows: the bottle placement operation of the bottle placement mechanism 5 is controlled by the number of bottle placements. If the number of bottle placements is less than the number of bottle groups M that can be placed on the bottle conveyor belt 2, and one of the two parallel conveyor tracks 3 has completed the batch filling operation, then the bottle placement mechanism 5 controls a group of bottles on the first conveyor track 3 to enter the bottle conveyor belt 2, the number of bottle placements is incremented by 1, and the information of this group of bottles is sent to the pump sampling array. If the number of bottle placements after incrementing by 1 is equal to the number of bottle groups M that can be placed on the bottle conveyor belt 2, then the information of the bottles in the pump sampling array is assigned to... The intermediate sampling array is used; at the same time, the bottle inlet detection sensor 13 detects the bottle inlet signal of the bottle conveyor belt 2 sent by the bottle inlet auger 11 into the online sampling and weighing mechanism 1. If the bottle inlet signal is detected, the cumulative number of bottles inlet is incremented by 1. The information of the bottle currently sent into the online sampling and weighing mechanism 1 is determined according to the cumulative number of bottles inlet and the intermediate sampling array. The bottle sent into the online sampling and weighing mechanism 1 is sampled and weighed, and the bottle information and the sampling and weighing results are associated and output. If the cumulative number of bottles inlet is equal to the number of bottles N in a set of bottles, the number of bottle releases is decremented by 1 and the cumulative number of bottles inlet is cleared to zero.

[0036] The specific process of the online sampling and weighing method of the double-row bottle conveyor belt in this embodiment is as follows: taking 12 filling needles on each conveyor track 3 and 3 groups of bottles (12 bottles per group) that can be placed on the bottle conveyor belt 2 as an example:

[0037] Assign numbers 1-12 to one row of filling needles on one conveyor track 3, and numbers 13-24 to the filling needles on the other conveyor track 3. Create a pump sampling array in the program to record the bottle sequence, and then create a transfer sampling array to temporarily store the bottle sequence status. Finally, create a final sampling array to determine the bottles to be sampled. After the first row of 12 bottles is placed, the numbers 1-12 will be stored in the first 12 characters of the pump sampling array, and the number of bottles dispensed will be recorded and the pump sampling array will be shifted 12 positions. After the second row of 12 bottles is placed, the numbers 13-24 will be stored in the first 12 characters of the pump sampling array, and the number of bottles dispensed will be recorded and the pump sampling array will be shifted 12 positions. During operation, the equipment typically alternates between placing 12 bottles in one row on one conveyor track 3 and 12 bottles in another row on another conveyor track 3, resulting in a bottle sequence of 24-1. However, sometimes a row may be missing a bottle. Therefore, this method can effectively prevent the problem of improper sampling caused by a missing bottle in a row disrupting the bottle sequence.

[0038] When the number of bottles dispensed is less than or equal to the set number, the data in the pump sampling array will be transferred to the transfer sampling array. When the bottle inlet detection sensor detects 13 bottles, it will count and count. Finally, the final sampling array [0] = transfer sampling array [12×3-cumulative number of bottles dispensed]. The final sampling array will move with the workstation. When the cumulative number of bottles dispensed is greater than or equal to 12, the cumulative number of bottles dispensed will be cleared to zero, and the number of bottles dispensed will be reduced by 1.

[0039] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
