The strip-pack apparatus is disposed directly under or in the vicinity of a transverse sealing apparatus in a bag making and packaging machine and has a configuration that moves products that have been supplied from the bag making and packaging machine to an affixing position where the products are affixed to the strip. For that reason, when the products that have been supplied are to be cartoned as they are without being formed into a strip pack, it is necessary to remove this strip-pack apparatus and install a cartoning machine instead of the strip-pack apparatus. Consequently, there has been the problem that the strip-pack apparatus cannot easily accommodate a change in production planning that calls for a layout change of apparatus elements.
It is an object of the present invention to provide a strip-pack apparatus that has excellent versatility and is capable of appropriately switching between forming and not forming products that have been supplied from an upstream side into a strip pack depending on circumstances on a downstream side while ensuring the manufacture of a strip pack where plural products are affixed to a strip.
In order to achieve this object, the present invention is configured as follows.
A strip-pack apparatus according to a first aspect of the present invention comprises moving means, affixing means, operating mode selecting means and control means, is positioned between an upstream mechanism and a downstream mechanism that process products, and manufactures a strip pack where a plurality of the products are affixed to a strip. The moving means selectively moves the products that have been supplied from the upstream mechanism to an affixing position or the downstream mechanism. The affixing means affixes the products to a strip in the affixing position. The operating mode selecting means receives a selection between a strip pack manufacturing mode and a product passing mode. The strip pack manufacturing mode is an operating mode that causes the moving means to move the products to the affixing position. The product passing mode is an operating mode that causes the moving means to move the products to the downstream mechanism without moving the products to the affixing position. The control means controls the driving of the moving means and the affixing means depending on the operating mode that has been selected via the operating mode selecting means.
A strip-pack apparatus according to a second aspect of the present invention is the strip-pack apparatus according to the first aspect of the present invention, wherein the moving means includes conveying means and gripping means. The conveying means conveys the products that have been supplied from the upstream mechanism to a gripping position. The gripping means grips the products in the gripping position and moves the products to the affixing position.
A strip-pack apparatus according to a third aspect of the present invention is the strip-pack apparatus according to the first aspect of the present invention, wherein the moving means includes first conveying means, second conveying means and third conveying means. The first conveying means conveys the products that have been supplied from the upstream mechanism to a branching position. The second conveying means conveys the products from the branching position toward the affixing position. The third conveying means conveys the products from the branching position toward the downstream mechanism. The control means controls the driving of the first conveying means, the second conveying means and the third conveying means such that, when the product passing mode has been selected via the operating mode selecting means, the products are moved to the downstream mechanism without being moved to the affixing position.
It will be noted that the first conveying means and the second conveying means may be integrally formed, the first conveying means and the third conveying means may be integrally formed, the second conveying means and the third conveying means may be integrally formed, or the first conveying means, the second conveying means and the third conveying means may be integrally formed.
A strip-pack apparatus according to a fourth aspect of the present invention is the strip-pack apparatus according to the third aspect of the present invention, wherein the third conveying means is detachably or movably connected to the first conveying means in the branching position.
A strip-pack apparatus according to a fifth aspect of the present invention is the strip-pack apparatus according to the first aspect of the present invention, wherein the moving means includes conveying means that is capable of conveying the products selectively in a first direction or a second direction different from the first direction. The control means causes the conveying means to move the products toward the affixing position by driving the conveying means in the first direction when the strip pack manufacturing mode has been selected via the operating mode selecting means and causes the conveying means to move the products toward the downstream mechanism by driving the conveying means in the second direction when the product passing mode has been selected via the operating mode selecting means.
According to the first aspect of the present invention, when the strip pack manufacturing mode is selected by the operating mode selecting means, the driving of the moving means and the affixing means is controlled by the control means, and the primary operation of the strip-pack apparatus, that is, operation to affix the plural products to the strip, is executed. In other words, the products that have been supplied from upstream are moved to the affixing position and the strip pack is efficiently manufactured. On the other hand, when the product passing mode is selected, the products that have been supplied from upstream are delivered as they are downstream, where, for example, a cartoning machine is disposed, without being moved to the affixing position. In this manner, there is realized a strip-pack apparatus that has excellent versatility and is capable of appropriately switching between forming and not forming a strip pack depending on circumstances on the downstream side.
According to the fourth aspect of the present invention, the third conveying means is detachably or movably disposed consecutively with the downstream side of the first conveying means. Consequently, when the product passing mode has been selected, the third conveying means is kept in the state where it is disposed consecutively with the downstream side of the first conveying means, so that the products that have been supplied from the upstream mechanism are capable of being carried reliably to the downstream mechanism without being supplied to the affixing position. Additionally, when the strip pack manufacturing mode is selected as the operating mode, it suffices to remove this auxiliary conveying means.
According to the fifth aspect of the present invention, the conveyance direction of the conveying means included in the moving means is capable of being switched between a direction (first direction) where the conveying means is capable of supplying the products toward the affixing position and a direction (second direction) where the conveying means is capable of carrying the products toward the downstream mechanism without supplying the products toward the affixing position. Consequently, by controlling the conveyance direction of the conveying means, it becomes possible to easily switch between the strip pack manufacturing mode and the product passing mode.

Below, embodiments of the present invention will be described.
The system shown in
The combination weighing device W respectively weighs the weights of goods that have been placed in plural measuring hoppers, performs combination calculation on the basis of these weighing values, selects a combination of weighing values that become the closest weight to a target value within a predetermined weight range, and discharges the goods from only the measuring hoppers corresponding to that selected combination to thereby obtain a set of goods with the target weight. Further, the bag making and packaging machine P forms a soft packaging material such as a plastic film into a tubular form, places the goods therein and simultaneously heat-seals the top and bottom of that tubular object to thereby package, as contents, the goods that are discharged from the combination weighing device W. Additionally, the cartoning machine C packs the products X that have been manufactured by the combination weighing device W and the bag making and packaging machine P into cardboard boxes, and an apparatus with an appropriate configuration is applicable.
A strip-pack apparatus shown in
Further, a metal detector 3a is supported on the body unit 2 and is annexed to the supply conveyor 3 so as to surround a conveyance path of the products X. This metal detector 3a detects metal foreign bodies that are mixed inside packaging bags Y of the products X when the products X pass through a magnetic field. Additionally, an air nozzle 3b for spraying air and removing the products X being conveyed from the conveyance path is annexed to one side in the vicinity of the downstream end of the supply conveyor 3. Moreover, an auxiliary conveyor 3c that serves as auxiliary conveying means that conveys the products X in the direction of arrow D1 is configured to extend the downstream end portion of the supply conveyor 3 and is detachably disposed consecutively with the body unit 2. And a receiving conveyor that supplies the products X to the cartoning machine C is installed consecutively with the downstream side of this auxiliary conveyor 3c. It will be noted that, in the example in the drawing, the receiving conveyor configures part of this cartoning machine C.
As shown in
Next, a control system of this strip-pack apparatus 1 will be described.
As shown in
Further, the control unit 20 receives a detection signal from the metal detector 3a and determines whether the products X are normal products or abnormal products on the basis of this detection signal. Additionally, when one of the products X is an abnormal product, the control unit 20 actuates and controls the air nozzle 3b such that the air nozzle 3b removes that product X to the side of the conveyance path.
Next, an example of the operation of the strip-pack apparatus 1 will be described.
First, when the manufactured products X are to be formed into the strip pack SP, an operator flips up the upstream end side of the auxiliary conveyor 3c or removes the entire auxiliary conveyor 3c from the body unit 2 and selects the strip pack manufacturing mode with the operating mode selection switch 30. Then, as shown in
Next, wrinkles in the end portions, that is, the seal portions, of the products X that have been determined to be normal products, have dropped from the supply conveyor 3 onto the introduction conveyor 4 below and have been conveyed to the gripping position in the direction of arrow D2 by the introduction conveyor 4 and the drop conveyor 5 are smoothed out by the brush unit 7, and the products X are moved diagonally downward of the front side in the conveyance direction D2 in a state where the end portions are gripped by the gripping unit 8. At this time, the drop conveyor 5 slants such that its front side in the conveyance direction D2 becomes lower.
Then, the plural products X are affixed by the affixing unit 9 in an affixing position to the tape T that has been let out by the tape feeding unit 10 from the tape roll 11 supported on the body unit 2 and fed to the affixing position, whereby the strip pack SP is manufactured. The strip pack SP that has been manufactured is delivered to the discharge conveyor 6 while sliding down on a slanted receiver 13 and is conveyed by this conveyor 6 in the direction of arrow D3.
On the other hand, when the manufactured products X are to be cartoned, the operator selects the product passing mode with the operating mode selection switch 30 and attaches the auxiliary conveyor 3c to the body unit 2. Thus, the products X that are conveyed by the supply conveyor 3 are delivered as they are to the auxiliary conveyor 3c and are conveyed in the downstream direction. Additionally, the control unit 20 performs control so as to stop the driving of all of the conveyors 4 to 6 and the units 7 to 10. Consequently, when the products X that have been supplied from the upstream side are determined to be normal products by the metal detector 3a, the products X are conveyed in the direction of arrow D1 and are delivered as they are, without being formed into the strip pack SP, from the supply conveyor 3 and the auxiliary conveyor 3c to the cartoning machine C on the downstream side. Additionally, when the products X are determined to be abnormal products, the air nozzle 3b is actuated and the products X are removed to the side of the conveyance path.
Further, when inspection by the metal detector 3a is stopped and the air nozzle 3b is not actuated, the strip-pack apparatus 1 can be made to function as simple conveying means that delivers the products X that have been supplied from the bag making and packaging machine P on the upstream side to the cartoning machine C on the downstream side.
That is, the course of the products X in the strip-pack apparatus 1 branches at the downstream end of the supply conveyor 3. When the strip pack manufacturing mode is selected, the products X are conveyed by the conveyors 4 and 5 toward the affixing position where the affixing operation by the affixing unit 9 is performed, and when the product passing mode is selected, the products X are conveyed by the conveyor 3c toward the cartoning machine C.
Next, a second embodiment will be described. It will be noted that, in order to simplify description, the same reference signs will be added to components that are the same as or similar to components that have been mentioned above, and description of those same or similar components will be omitted.
A manufacturing system shown in
As shown in
As shown in
Further, the control unit 20 receives a detection signal from the metal detector 3a and determines whether the products X are normal products or abnormal products on the basis of this detection signal. Additionally, when one of the products X is an abnormal product, the control unit 20 actuates and controls the air nozzle 3b such that the air nozzle 3b removes that product X to the side of the conveyance path.
Next, an example of the operation of the strip-pack apparatus 100 will be described.
First, when the manufactured products X are to be formed into the strip pack SP, the operator selects the strip pack manufacturing mode with the operating mode selection switch 30. Then, as shown in
Next, the products X that have been determined to be normal products and have dropped from the supply conveyor 3 onto the introduction conveyor 4 are conveyed to the gripping position in the direction of arrow D2 by the introduction conveyor 4 and the drop conveyor 5, but the operation hereinafter is the same as the operation in the first embodiment, so description thereof will be omitted.
On the other hand, when the manufactured products X are to be cartoned, the operator selects the product passing mode with the operating mode selection switch 30. In this case, the control unit 20 stops the driving of all of the conveyors 5 and 6 and the units 7 to 10 and controls the introduction conveyor 4 such that the introduction conveyor 4 conveys the products X in the direction of arrow D4. Consequently, when the products X that have been supplied from the upstream side are determined to be normal products by the metal detector 3a, the products X are conveyed in the direction of arrow D1, thereafter drop onto the introduction conveyor 4, and are conveyed by this introduction conveyor 4 in the direction of arrow D4, so the products X are delivered as they are, without being formed into the strip pack SP, from the introduction conveyor 4 to the cartoning machine C on the downstream side. Additionally, when the products X are determined to be abnormal products, the air nozzle 3b is actuated and the products X are removed to the side of the conveyance path.
Further, when inspection by the metal detector 3a is stopped and the air nozzle 3b is not actuated, the strip-pack apparatus 100 can be made to function as simple conveying means that delivers the products X that have been supplied from the bag making and packaging machine P on the upstream side to the cartoning machine C on the downstream side.
Because the strip-pack apparatus is configured as described above, first, when the strip pack manufacturing mode is selected by the operating mode selection switch 30 in order to form the manufactured products X into the strip pack SP, the driving of the supply conveyor 3, the gripping unit 8 and the affixing unit 9 is controlled by the control unit 20, and the primary operation of the strip-pack apparatus 1 and 100 is executed. As a result, the products X that have been supplied from the upstream side are conveyed to the gripping position and the strip pack SP is efficiently manufactured. On the other hand, when the product passing mode is selected in order to carton the manufactured products X, the products X that have been supplied from the upstream side are conveyed as they are to the downstream side without being conveyed to the gripping position, so the strip-pack apparatus 1 and 100 function as apparatus that deliver the products X that have been received from the upstream side as they are to the cartoning machine C. In this manner, there are realized the strip-pack apparatus 1 and 100 that have excellent versatility and are capable of appropriately switching between forming and not forming the products X that have been supplied from the upstream side into the strip pack depending on a request on the downstream side.
In that case, as in the first embodiment, the auxiliary conveyor 3c can be detachably disposed consecutively with the downstream side of the supply conveyor 3 or can be given a flip-up configuration. For that reason, when the product passing mode has been selected as the operating mode, the products X that have been supplied from the upstream side can be reliably conveyed to the downstream side by the auxiliary conveyor 3c with this configuration without being conveyed to the gripping position. Additionally, when the strip pack manufacturing mode has been selected as the operating mode, it suffices to remove or flip up this auxiliary conveyor 3c.
In the second embodiment, the introduction conveyor 4 that is capable of being driven in a direction where it is capable of supplying the products X to the gripping position or a direction where it is capable of carrying the products X to the downstream side without supplying the products X to the gripping position is disposed on the downstream side and below the supply conveyor 3. Therefore, by controlling this introduction conveyor 4, it becomes possible to easily switch between when the strip pack manufacturing mode has been selected and when the product passing mode has been selected as the operating mode.
It will be noted that the present invention is not limited to the preceding embodiments that have been specifically described and various changes to the described embodiments may be made within the spirits of the present invention.
For example, in the first embodiment, the auxiliary conveyor 3c is capable of being disposed between the supply conveyor 3 and the cartoning machine C, but instead of this, the cartoning machine C may also be configured so as to be movable such that it moves close to the downstream end portion of the supply conveyor 3.
As described above, according to the present invention, there is realized a strip-pack apparatus that has excellent versatility and is capable of appropriately switching between forming and not forming products into a strip pack depending on circumstances on a downstream side while ensuring the efficient manufacture of a strip pack where plural products are affixed to a strip. That is, the present invention is widely suited to the technical field of strip packs.
