DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging apparatus for packaging fruits, hen eggs, etc., whose properties such as weight, size, shape and the like vary.

[0002]

2. Description of the Related Art For example, in the sorting and packaging of eggs whose weight classification is usually 7 grades, a packing place is provided for each weight classification,
The eggs weighed are sorted and sorted to the corresponding packaging places, and the eggs sorted to each of the packaging places are then stored in a packaging container and packaged by a storage device provided for each weight division. . By the way, the central value of the weight distribution of chicken eggs changes little by little depending on the age of the chickens, and the egg weight is not evenly distributed. Therefore, the egg storage devices for the weight categories other than the eggs corresponding to the weight category corresponding to the weight category at the center of the weight distribution become substantially idle and have an extremely low operation rate. For this purpose, a storage device must be installed, and an installation space for it must be provided. Therefore, the present applicant can provide at least one shared storage device as disclosed in Japanese Patent Publication No. 4-76847, whereby the number of storage spaces can be reduced, thereby saving space and reducing equipment costs.

In the lowered position, the lifting device 94 allows only the protector 2 from which the eggs 3 have been removed to move in the D direction.

The lifting device 94 has as many suction arms 99 as can be accommodated in a line on one side of the packaging container 16, and a rotatable, telescopic support arm 10 for supporting the suction arms 99.
The suction arm 99 operates so as to suck and take out the chicken eggs 3 of the protective equipment 2 retained on the conveyor 90 by the rotation and expansion and contraction of the support arm 100, and put them into the packaging container 16. . After the conveyer 95 carries out the packaging container 16 in which all the eggs 3 are packed, the traveling is stopped to support the new packaging container 16. The collection of the eggs 3 in the package at the collecting place 14 is performed by appropriate means.

The packaging apparatus 1 is provided with a setting device 111 capable of setting a combination weight category of eggs to be packaged in the packaging container 16.
It is assumed that the setting unit 111 sets that one egg of each of the weight categories SS, S, MS and 2L and three eggs of each of the weight categories M and L are to be packed. The setting value set by the setting unit 111 is also stored in the storage unit 26.
Is stored.

The storage means 26 further stores a control program for causing the gates 41 to 47 and the like to perform the following operations in addition to the above. Based on the control program stored in 26, gates 41 to 47 and the like described below are operated.

The operation of the packaging device 1 will be described below. In addition,
The allocation updating means 24 firstly assigns the eggs corresponding to the weight division SS to the collection section 7, the eggs corresponding to the weight division S to the collection section 8, the chicken eggs corresponding to the weight division MS to the collection section 9, the weight division The eggs corresponding to M are placed in the collecting section 10, the eggs corresponding to the weight section L are placed in the collecting section 11, and the weight section 2 is placed in the collecting section 11.
The eggs corresponding to L are collected in the collection section 12, respectively.
Allocated eggs are assigned to the collecting section 13 so as not to be collected. Therefore, for example, weight division SS
The protective equipment 2 containing the eggs 3 corresponding to
, The gate 41 is rotated by the motor 51, and the protective device 2 is transferred to the conveyor 31. The same applies to the other gates 42 to 46. The non-standard chicken eggs 3 are sent to the collecting place 14.

The eggs 3 stored in the protective equipment 2 are
Are sequentially conveyed and brought on the conveyor 21, the detector 21 detects the weight of the egg 3, and the detected weight is supplied to the control device 25. The control device 25
The position where the egg 3 indicating the detected weight is conveyed by the conveyor 27 is calculated based on the travel distance from the detector 58,

When the egg 3 arrives at one end of the
By operating the corresponding motor 57, one of the gates 41 to 47 is rotated, and the eggs 3 are conveyed to the conveyors 31 to 47.
Shift to one of 37. The eggs 3 transferred to each of the conveyors 31 to 37 are collected and stored on the conveyors 31 to 37 as long as the gates 61 to 67 are closed.

The storage means 26 stores information on the combination of one egg in each of the weight categories SS, S, MS and 2L and three eggs in each of the weight categories M and L in one package. Therefore, the control device 25 controls the gates 61, 62 and 64 until one object passing signal is received from each of the detectors 81 and 82 and three from the detector 84 in one half cycle of one packaging operation. The motors 71 to 77 are operated so as to open. The gates 61 to 67 are opened and closed on the conveyor 88 in such an order that the protective devices 2 do not overlap each other.

5 chicken eggs 3 transferred to the conveyor 88
Are sequentially conveyed in the C direction by the conveyor 88 and sent out to the conveyor 90. After issuing five object passing signals from the detector 89, the five eggs 3 are conveyed by the conveyor 90 to the D position.
When the chickens 3 are conveyed in the direction and stopped by being arranged in a row by the gate 91, the lifting device 94 is operated, and the five eggs 3 arranged and stopped in a row are sucked by the arm 99 and packed. The container 16 is placed in one of the accommodation seats.
Thereafter, the gate 91 is lowered, only the protective device 2 is transported and discharged in the direction D, and the gate 91 is raised again.
In the remaining half cycle of one package, detectors 83 and 8
Gates 63, 66 and 65 are opened until one object passing signal from 6 and three object passing signals from detector 85 are respectively generated. Then, as described above, when the five chicken eggs 3 are arranged in a row on the conveyor 90 and stopped,
The lifting device 94 puts the five eggs 3 into the remaining storage seats of the packaging container 16. When a total of ten eggs 3 are stored in the packaging container 16, the motor 98 is operated, and the packaging container 16 is transported in the E direction and discharged. Then, after discharging, a new empty packaging container 16 is placed on the conveyor 95 automatically or manually. When this one wrapping operation is completed, the next wrapping operation is repeated.

When the above-described packaging operation is repeated, the protective gear 2 containing the eggs 3 may stay on the collecting conveyors 31 to 37 of the collecting sections 7 to 13. However, the calculating means 28 of the control device 25 , The accumulated amount, that is, the collecting sections 7 to 13
The number of eggs 3 currently gathered at the gates 41-47
, And the number of times the gates 61 to 67 are opened and closed, or the object passing signal from the detectors 81 to 87, is constantly calculated. Then, in any one of the collecting conveyors 31 to 37, the comparison and inspection means 29 checks that the number of sets has become the number of eggs that can be collected in the collecting section.
Is detected, the control device 25 assigns the collection section 13 that has not been used so far to the collection section for the eggs in the weight section that has been collected on the collection conveyor in which the collection number has reached the number of eggs that can be collected. The gate 47 is arranged so that the chicken eggs 3 are also distributed to the conveyor 37 of the collecting section 13.
Open and close. The opening and closing of the gate and the newly assigned gate 47 for the collecting conveyor whose number of collected eggs has reached the number of eggs that can be collected may be alternate, or may be performed in response to an increase or decrease in the number of collected eggs. The opening and closing of the gate and the gate 67 with respect to the downstream end of the collection conveyor where the collection number has reached the number of eggs that can be collected may also be performed alternately or in response to an increase or decrease in the number of collections. In short, the opening and closing of the gate is controlled so that the number of eggs does not exceed the number of eggs that can be collected. When chickens 3 of different ages are sequentially supplied to the conveyor 5, the above-described operation is repeated, and the weight division with the highest supply frequency is assigned to the empty collection section.

As described above, in the packaging apparatus 1, since another separate collection section can be assigned to the weight section most frequently supplied in packaging eggs of that age, the weight distribution changes depending on the age of the chicken. Even in this case, it is not necessary to secure the space of the collective section of all the weight sections for the expected maximum supply frequency, so that the occupied area of the collective section can be reduced, and the installation space of the equipment is reduced. can do.

Incidentally, in the above example, Japanese Patent Publication No. 3-5777

In addition, the same effect can be obtained by providing the number of property sections having different number of collectable sections from each other by providing the number of property sections substantially the same as the number of property sections.

Further, as shown in FIG. 4, in the eggs 3 supplied from the weight detecting means 6, the eggs 3 in the weight category having the highest predicted supply frequency are collected in any of the collecting sections 7 to 13. Instead, the packaging apparatus 101 may be configured to be directly conveyed to the storage station 18 via the distribution conveyor 27 and the belt conveyors 100 and 90, and to operate the other components in the same manner as described above. In this case, the stop gate 111, the distribution gates 112 and 11
3 and two belt conveyors 114 and 115 are provided,
When packing the eggs 3 of the weight category with the highest supply frequency, the stop gate 111 is opened and the belt conveyor 100 is opened.
Of the eggs 3 from the belt conveyor 90 to the belt conveyor 90, the sorting gates 112 and 113 are appropriately operated, and the eggs 3 of the weight category most frequently supplied from the belt conveyor 90 are transferred to the belt conveyors 114 and 115, respectively. When the eggs 3 are wrapped, the stop gate 111 is closed and the belt conveyor 100 is closed.
The transfer of the eggs 3 from the belt conveyor 90 to the belt conveyor 90 is stopped and the eggs 3 are temporarily retained on the belt conveyor 100, and the sorting gates 112 and 113 are appropriately operated to transfer the eggs 3 from the belt conveyors 88 and 90 to the belt conveyor 90. You may make it distribute to 114 and 115, respectively. The packaging apparatus 101 of the present example is also configured such that the belt conveyor 1 is manually operated by an operator at the storage station 18.
The eggs 3 from 14 and 115 are packed in the packaging container 16, and the stop gate 111 is opened and closed to pack the eggs 3 of the weight category with the highest supply frequency, or to pack other eggs 3. The selection is made, for example, by operating a selection switch provided in the accommodation station 18 by an operator, and the control device 25 controls each of the above operations by a selection signal of the selection switch. The configuration is as follows. The processing of the non-standard chicken eggs 3 in the packaging apparatus 101 shown in FIG. 4 may be appropriately excluded from the distribution conveyor 27.

Further, in the above specific example, the distribution conveyor 27 is formed by a belt conveyor, and the eggs 3 are stored in the protector 2, but instead, as shown in FIG.

As described above, according to the present invention, fruits, chicken eggs, and the like, whose weight, size, shape and the like vary, can be packed in a small occupied space. That is,
According to the present invention, at least one more set section is arranged than the number of property sections to be selected, and the assignment updating means sets the property section set in the set section whose set number has reached the settable number. By assigning at least two assembly sections as the assembly section for the packaged item, and updating the assignment of the assembly section to each property section, the length of each assembly section in the assembly direction can be shortened. The space related to the length of the whole section in the collecting direction can be reduced. In other words, according to the present invention, the package of the property section that has reached the collectable number appropriately corresponds to the package of the property section that reaches the collectable number that varies depending on the producer or the production location. At least two collective compartments can be used as collective compartments, and at least one collective compartment can be used as a common collective compartment. Occupied space can be reduced. Furthermore, according to the present invention, at least two collection sections are allocated as a collection section for the package of the property section which is collected in the collection section in which the collection number has reached the collectable number. In the inconvenience due to the number of sets reaching the settable number in the set section, that is, the inconvenience due to a full state in any of the set sections, for example,
It is possible to prevent a decrease in the operating rate of the entire apparatus due to a temporary stoppage of the operation of the apparatus for eliminating the full state, and to operate the apparatus efficiently. Further, according to the present invention, according to the frequency of occurrence of each property section of the supplied packaged goods, the sorting and collecting means sets at least two collection sections as a collection section for the package of the property section with the highest frequency of occurrence. Since there is provided an assignment updating means for updating the assignment of the collective section to each property section by allocating, the occurrence of a full state in the collective section can be avoided as much as possible, and the operation of the apparatus is temporarily stopped. This can reduce the possibility that the operation rate of the entire apparatus will decrease, and can operate the apparatus efficiently.
