Description

Technical Field

[0001] The invention relates to the technical field of food and medicine packaging equipment, and in particular to an online sampling and weighing method for a double-row bottle conveying mesh belt. Background Art

[0002] The existing online sampling and weighing device for bottle conveying mesh belt is generally a single-row bottle conveying mesh belt conveying and filling device, including a bottle conveying mesh belt and a weighing mechanism arranged along one row, and a filling mechanism arranged on the bottle conveying mesh belt. The single-row bottle conveying and filling device has low production efficiency. At present, in order to improve production efficiency, a multi-row bottle conveying mesh belt online sampling and weighing device can be equipped. However, each row of bottle conveying mesh belt conveying and filling has a weighing mechanism, which occupies a large area and is costly. If a double-row bottle conveying mesh belt is used to convey and fill a bottle and share a weighing mechanism, if a bottle conveying mesh belt is short of bottles, the bottle sequence will be disordered, resulting in failure to sample normally, making it difficult to match the weighed bottle with the filling needle of the filling mechanism. In this way, once the bottle filling amount does not meet the standard, it is difficult to find the filling pump connected to the corresponding 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 a double-row bottle conveying mesh belt online sampling and weighing method that meets the normal sampling requirements of an online sampling and weighing mechanism, can match the weighed bottles with the filling needles of the filling mechanism to fill them, and can accurately find the filling pumps corresponding to the bottles that do not meet the filling standards.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A double-row bottle conveying mesh belt online sampling and weighing method is performed using a double-row bottle conveying mesh belt online sampling and weighing device. The double-row bottle conveying mesh belt online sampling and weighing device comprises an online sampling and weighing mechanism. The feeding side of the online sampling and weighing mechanism is provided with a bottle feeding detection sensor and a bottle conveying mesh belt. The feeding side of the bottle conveying mesh belt is provided with two parallel conveying tracks. Each conveying track is provided with a corresponding filling mechanism. The filling mechanism has N filling needles for batch filling operations. The discharging side of the two parallel conveying tracks is provided with an interlocking bottle placing mechanism for controlling the bottles on the single conveying track to enter the bottle conveying mesh belt. The double-row bottle conveying mesh belt online sampling and weighing method comprises the following steps:

[0006] S1, initialize the number of bottle placements to 0 and the pump sampling array to be empty;

[0007] S2, control the bottle placing operation of the bottle placing mechanism by the bottle placing times. If the bottle placing times is less than the number of bottle groups M that can be placed on the bottle conveying mesh belt and there is a conveying track that has completed the batch filling operation among the two parallel conveying tracks, the bottle placing mechanism controls a group of bottles on the conveying track that has completed the batch filling operation first to enter the bottle conveying mesh belt, and the bottle placing times are increased by 1 and the information of the group of bottles is sent to the pump sampling array. If the bottle placing times after the increase of 1 is equal to the number of bottle groups M that can be placed on the bottle conveying mesh belt, the information of the bottles in the pump sampling array is sent to the pump sampling array. Assign values ​​to the transfer sampling array; at the same time, detect the bottle-incoming signal of the online sampling and weighing mechanism through the bottle-incoming detection sensor. If the bottle-incoming signal is detected, the cumulative number of bottle-incoming is increased by 1, and the information of the bottle currently sent to the online sampling and weighing mechanism is determined according to the cumulative number of bottle-incoming and the transfer sampling array, and the bottle sent to the online sampling and weighing mechanism is sampled and weighed, and the bottle information is associated with the sampling and weighing results and then output; if the cumulative number of bottle-incoming is equal to the number of bottles N in a group of bottles, the number of bottle placements is reduced by 1 and the cumulative number of bottle-incoming is cleared.

[0008] As a further improvement of 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 backward 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 M of bottle groups that can be placed on the bottle conveying mesh belt is 3.

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

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

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

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

[0015] A bottle-inlet auger and a bottle-outlet dial wheel are arranged between the online sampling and weighing mechanism and the bottle-conveying mesh belt, and the bottle-inlet detection sensor is arranged at the entrance of the bottle-inlet auger.

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

[0017] The double-row bottle conveying mesh belt online sampling and weighing method of the present invention adopts an online sampling and weighing mechanism shared by two conveying tracks. The bottle placing mechanism controls a group of bottles on one conveying track that completes the batch filling operation first to enter the bottle conveying mesh belt 2, so that the bottles on the two conveying tracks enter the bottle conveying mesh belt in groups according to the order of filling completion; the number of bottle placing is increased and the information of the group of bottles is sent to the pump sampling array. If the number of bottle placing after adding 1 is equal to the number of bottle groups M that can be placed on the bottle conveying mesh belt, the information of the bottles in the pump sampling array is assigned to the transfer sampling array, that is, after the bottle conveying mesh 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 the bottles on the bottle conveying mesh belt; at the same time, the bottle inlet detection sensor detects the number of bottles on the online sampling weighing The bottle feeding signal of the weighing mechanism is detected. If the bottle feeding signal is detected, the cumulative number of bottle feedings is increased by 1, and the information of the bottle currently sent to the online sampling and weighing mechanism is determined according to the cumulative number of bottle feedings and the transfer sampling array, and the bottle sent to the online sampling and weighing mechanism is sampled and weighed, and the bottle information and the sampling and weighing result are associated and output. In this way, the information of the bottle currently sent to the online sampling and weighing mechanism is determined according to the cumulative number of bottle feedings and the transfer sampling array, so that each bottle entering the online sampling and weighing mechanism can find the pump for filling it according to the information, meeting the normal sampling requirements of the online sampling and weighing mechanism 1, so that the weighed bottle can be matched with the filling needle used by the filling mechanism to fill it. Once the bottle filling amount does not meet the standard, the filling pump connected to the corresponding filling needle can be accurately found. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1 An embodiment of the double-row bottle conveying mesh belt online sampling and weighing method of the present invention is shown. The double-row bottle conveying mesh belt online sampling and weighing method of the present embodiment is performed by using a double-row bottle conveying mesh belt online sampling and weighing device. The double-row bottle conveying mesh belt online sampling and weighing device comprises an online sampling and weighing mechanism 1. The feeding side of the online sampling and weighing mechanism 1 is provided with a bottle feeding detection sensor 13 and a bottle conveying mesh belt 2. The feeding side of the bottle conveying mesh belt 2 is provided with two parallel conveying tracks 3. Each conveying track 3 is provided with a corresponding filling mechanism 4. The filling mechanism 4 has N filling needles for batch filling operations. The discharging side of the two parallel conveying tracks 3 is provided with an interlocking bottle placing mechanism 5 for controlling the bottles on the single conveying track 3 to enter the bottle conveying mesh belt 2. The double-row bottle conveying mesh belt online sampling and weighing method comprises the following steps:

[0026] S1, initialize the number of bottle placements to 0 and the pump sampling array to be empty;

[0027] S2, control the bottle placing operation of the bottle placing mechanism 5 by the bottle placing times. If the bottle placing times is less than the number of bottle groups M that can be placed on the bottle conveying mesh belt 2 and there is a conveying track 3 that has completed the batch filling operation among the two parallel conveying tracks 3, the bottle placing mechanism 5 controls a group of bottles on the conveying track 3 that has completed the batch filling operation first to enter the bottle conveying mesh belt 2, and the bottle placing times is increased by 1 and the information of the group of bottles (the group of bottles placed) is sent to the pump sampling array. If the bottle placing times after the increase of 1 is equal to the number of bottle groups M that can be placed on the bottle conveying mesh belt 2, the information of the bottles in the pump sampling array is assigned to the middle transfer sampling array; at the same time, the bottle-incoming signal of the online sampling and weighing mechanism 1 is detected by the bottle-incoming detection sensor 13. If the bottle-incoming signal is detected, the cumulative number of bottle-incoming is increased by 1, and the information of the bottle currently sent to the online sampling and weighing mechanism 1 is determined according to the cumulative number of bottle-incoming and the transfer sampling array, and the bottle sent to the online sampling and weighing mechanism 1 is sampled and weighed, and the bottle information and the sampling and weighing result are associated and output; if the cumulative number of bottle-incoming (the cumulative number of bottle-incoming of the online sampling and weighing mechanism 1) is equal to the number of bottles N in a group of bottles, the number of bottle placements is reduced by 1 and the cumulative number of bottle-incoming is cleared.

[0028] The present double-row bottle conveying mesh belt online sampling and weighing method adopts an online sampling and weighing mechanism 1 shared by two conveying tracks 3. The bottle placing mechanism 5 controls a group of bottles (the conveying track 3 can accommodate multiple groups of bottles) on one conveying track 3 that has completed the batch filling operation first to enter the bottle conveying mesh belt 2, so that the bottles on the two conveying tracks 3 enter the bottle conveying mesh belt 2 in groups according to the order of filling completion; the number of bottle placing times is increased by 1, and the information of the group of bottles (the group of placed bottles) (such as bottle number, pump number, and / or the signal corresponding to the bottle number and the pump number) is sent to the pump sampling array. If the number of bottle placing times after the increase of 1 is equal to the number of bottle groups M that can be placed on the bottle conveying mesh belt 2, the information of the bottles in the pump sampling array is assigned to the transfer sampling array, that is, after the bottle conveying mesh belt 2 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 conveying mesh belt 2; At the same time, the bottle-incoming signal of the online sampling and weighing mechanism 1 is detected by the bottle-incoming detection sensor 13. If the bottle-incoming signal is detected, the cumulative number of bottle-incoming is increased by 1, and the information of the bottle currently sent to the online sampling and weighing mechanism 1 is determined according to the cumulative number of bottle-incoming and the transfer sampling array, and the bottle sent to the online sampling and weighing mechanism 1 is sampled and weighed, and the bottle information and the sampling and weighing result 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 bottle-incoming and the transfer sampling array, so that each bottle entering the online sampling and weighing mechanism 1 can find the pump for filling it according to the information (such as the information corresponding to the bottle number and the pump number), so as to meet the normal sampling of the online sampling and weighing mechanism 1, so that the weighed bottle can be matched with the filling needle of the filling mechanism to fill it. Once the bottle filling amount does not meet the 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 backward 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 M of bottle groups that can be placed on the bottle conveying mesh belt 2 is 3.

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

[0032] Furthermore, in this embodiment, when the information of the bottle currently fed into the online sampling and weighing mechanism 1 is determined 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 fed into the online sampling and weighing mechanism 1 in the transfer sampling array is [M×N-cumulative number of bottles fed into the mechanism].

[0033] Furthermore, in this embodiment, after the information of the bottle currently fed into the online sampling and weighing mechanism 1 is determined, a sampling array is used to record the information of the bottle currently 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 fed into the online sampling and weighing mechanism 1 includes shifting the data in the sampling array back one position, and then inserting the information of the bottle currently fed into the online sampling and weighing mechanism 1 into the first position in the sampling array.

[0035] Furthermore, in this embodiment, a bottle feeding auger 11 and a bottle discharging dial wheel 12 are provided between the online sampling and weighing mechanism 1 and the bottle conveying mesh belt 2, and a bottle feeding detection sensor 13 is provided at the entrance of the bottle feeding auger 11. At this time, the specific process of S2 is: the bottle placing operation of the bottle placing mechanism 5 is controlled by the bottle placing number. If the bottle placing number is less than the number of bottle groups M that can be placed on the bottle conveying mesh belt 2 and there is a conveying track 3 that has completed the batch filling operation among the two parallel conveying tracks 3, then the bottle placing mechanism 5 controls a group of bottles on the conveying track 3 that has completed the batch filling operation first to enter the bottle conveying mesh belt 2, the bottle placing number is increased by 1, and the information of the group of bottles is sent to the pump sampling array. If the bottle placing number after the increase is equal to the number of bottle groups M that can be placed on the bottle conveying mesh belt 2, the information of the bottles in the pump sampling array is assigned to transfer sampling array; at the same time, the bottle feeding detection sensor 13 detects the bottle feeding signal of the bottle feeding auger 11 to send the bottles on the bottle conveying mesh belt 2 into the online sampling and weighing mechanism 1. If the bottle feeding signal is detected, the cumulative number of bottle feeding is increased by 1, and the information of the bottles currently sent to the online sampling and weighing mechanism 1 is determined according to the cumulative number of bottle feeding and the transfer sampling array, and the bottles sent to the online sampling and weighing mechanism 1 are sampled and weighed, and the bottle information and the sampling and weighing results are associated and output; if the cumulative number of bottle feeding is equal to the number of bottles N in a group of bottles, the number of bottle placements is reduced by 1 and the cumulative number of bottle feeding is reset to zero.

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

[0037] Assign numbers 1-12 to a row of filling needles on one conveyor track 3, and assign numbers 13-24 to the filling needles on another conveyor track 3. In the program, make a pump sampling array to record the bottle sequence, and then establish a transfer sampling array to temporarily store the bottle sequence status; then establish a final sampling array to determine the final sampled bottles; when the first row of 12 bottles are placed, the numbers 1-12 will be stored in the first 12 words of the pump sampling array, and the number of bottle discharges will be recorded and the pump sampling array will be shifted by 12 positions; when the second row of 12 bottles are placed, the numbers 13-24 will be stored in the first 12 words of the pump sampling array, and the number of bottle discharges will be recorded and the pump sampling array will be shifted by 12 positions. During the operation of the equipment, a row of 12 bottles on one conveyor track 3 and a row of 12 bottles on another conveyor track 3 are usually placed alternately, so the bottle sequence is 24-1. However, sometimes there will be a lack of bottles in a row, so this method can effectively avoid the problem of normal sampling when the bottle sequence is disrupted due to a lack of bottles in a row.

[0038] When the number of bottle discharges 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 input detection sensor detects 13 bottles, it will count and eventually, the final sampling array [0] = transfer sampling array [12×3-the cumulative number of bottles input]. The final sampling array will shift with the workstation. When the cumulative number of bottles input is greater than or equal to 12, the cumulative number of bottles input will be cleared and the number of bottles released will be reduced by 1.

[0039] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
