BACKGROUND OF THE INVENTION
The present invention includes a product conveying device for sending a product as a package to a packaging machine, a packaging machine for packaging the product with the packaging material by sealing the packaging material into which the product is fed, and a controller for controlling these. The packaging system.
[0002]
[Prior art]
Conventionally, as seen in horizontal pillow packaging machines, packaging machines combined with product supply devices such as belt conveyors form web-like packaging materials into tubes by center seals, and packaging that is shaped into tubes The product is supplied to the inside of the material, and the end seal that welds the tube-shaped packaging material at the front and back positions of the product with a high-temperature end sealer that performs rotation and box motion operation, and put the product in the bag We produce bag packages that are packed in The operation speed of the feed conveyor that feeds the product into the packaging material is variable according to the packaging processing speed, but in order to maintain the cut size of the package and the product interval, the speed of the packaging machine, that is, the packaging material feed rate. A one-to-one correspondence with the operating speed of the end sealer is maintained.
[0003]
In a packaging machine combined with such a product supply device, if the packaging machine continues to operate at a constant speed even when the supplied product interval exceeds a certain level, an empty bag containing no product will be produced. Become. In order to avoid the occurrence of such a situation, the operation of the packaging machine is temporarily stopped when the supply of the product is interrupted or when the product interval exceeds a certain value. However, if the stop timing of the packaging machine is not taken into consideration, there is a possibility that the high-temperature end sealer stops while still in contact with the packaging material. If the end sealer is in contact with the packaging material for a long time, the packaging material may melt by heat and contaminate the packaging machine or the end sealer. This will cause the operating rate to decrease. In addition, if the product supply device is not stopped even if the packaging machine is stopped, the product at the transition position (transfer position) between the conveyors is subjected to the feeding action from the operating product supply device, and the product interval is reduced. There is also a possibility that the end sealer bites the product when resuming the packaging, deviating from the predetermined product pitch.
[0004]
As an example of an apparatus for supplying a package to a packaging machine, Japanese Patent Application Laid-Open No. 7-81734 discloses that a package is continuously fed into a film in a desired relative positional relationship regardless of the size of the package. Has been. According to this supply device, the first conveyor device capable of increasing / decreasing the interval of the packages conveyed at random to a constant interval, and the second conveyor device arranged at the subsequent stage of the first conveyor device to supply the packages at a constant speed. A conveyor device and a third conveyor device that temporarily stops following the operation of the packaging machine are provided, and the second conveyor device and the third conveyor device are moved back and forth while maintaining their relative positions. It is configured as a shuttle type conveyor mechanism that can adjust the transport distance of the three conveyor device. When the third conveyor device is temporarily stopped together with the packaging machine, as in the case where the supply of the package is temporarily interrupted, the second conveyor device and the third conveyor device 3 so that the package does not exist across both conveyor devices. The crossing position with the conveyor device can be adjusted, and the end seal is the packaging material while maintaining the predetermined interval and the length of the cut dimension of the product by keeping the package at a predetermined stop position on the third conveyor device. It is possible to make it open so that it does not come into contact with.
[0005]
Japanese Patent Laid-Open No. 2000-211734 discloses a package transport and supply device that can change the crossing position in accordance with the cut dimensions. According to this package transport and supply device, the separation belt or the main body drive belt is interposed between the separation belt that can change speed with respect to the uppermost transport belt and the main body drive belt that operates in synchronization with the packaging machine. One or a plurality of transition belts that are driven in synchronism with one side are provided. As with the product supply device described in the previous publication, when the supply of the package is temporarily interrupted, the transition belt located on the separation belt side is synchronized with the separation belt and driven by the main body. By synchronizing the belt side with the main body drive belt, the position separating the separation belt side and the main body drive belt side is switched, and the crossover position is changed by switching the separation position, so that the predetermined interval of the product In addition, while maintaining the length of the cut dimension, the stop position of the end seal when the packaging machine is temporarily stopped together with the main body drive belt is set as an open position that does not contact the packaging material.
[0006]
When the packaging machine is paused, the end seal can be moved to the open position to avoid contact with the packaging material, and the end of the packaging can be maintained at the crossover position even when the packaging machine resumes operation. Corresponding to the end seal for avoiding contact with the packaging material, the distance between the seal position and the transition position is set to a preset length, that is, an integral multiple of the cut dimension corresponding to the length of one package. It is necessary to make the length the offset amount (for example, half of the cut size) added. Various quantities such as packaging dimensions in the packaging machine generally differ depending on the type of product that is the package, and in the case of a packaging machine where the transition position cannot be changed, the distance from the transition position to the position of the end sealer is However, it does not always match the added length. Therefore, in the conventional packaging machine, as described above, the distance from the crossover position to the end sealer position is changed to the above-mentioned added length by changing the crossover position of the product to the feed conveyor corresponding to the vacant product. It has been proposed to match. However, the use of a shuttle type conveyor mechanism for changing the crossing position has a problem that the structure of the product supply apparatus is complicated and the manufacturing cost of the packaging machine is increased. The crossover position of the shuttle type conveyor mechanism can be adjusted steplessly, but the crossover position must be changed manually or electrically for each cut size. Further, when one or a plurality of transition belts are disposed between the separation belt and the main body drive belt, it is basically impossible to adjust steplessly and the transition position is finely adjusted. However, it is necessary to increase the number of crossing belts, which also complicates the structure.
[0007]
[Problems to be solved by the invention]
Therefore, when the end seal is stopped in an open state to avoid contact with the packaging material when the packaging machine is temporarily stopped due to temporarily stopping the supply of the product as a package, There is a problem to be solved in that the drive is controlled by software, and the product can be supplied in the same manner as the transition position is changed.
[0008]
The object of the present invention is to change the transition position mechanically steplessly by dealing with the operation control without complicating the structure of the product conveying device in comparison with the conventional product conveying device. It is providing the packaging system which can acquire the effect similar to that of.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a packaging system according to the present invention includes a product conveyor having a transport conveyor on which a product passage sensor for detecting the passage of a product is disposed, and a feed conveyor connected at a transfer position on the carry-out side, and A wrapping machine having a wrapping material feeding means for wrapping a product to be wrapped at a predetermined interval by a feed conveyor together with the product, and a sealer for sealing the wrapping material to seal the wrapping material for wrapping the product; and A controller for controlling the operation of the feeding conveyor, the packaging material feeding means and the sealer, In response to the product passage sensor detecting the product interval above a certain level When the packaging machine stops , According to the stop position set as a position where the sealer avoids contact with the packaging material and stops, the interval between the products delivered to the feeding conveyor is set.
[0010]
The product conveyed by the product conveying device is transferred from the conveying conveyor to the feeding conveyor through the transfer position on the carry-out side. When there is a large gap between products due to product supply interruptions on the conveyor, the product passage sensor detects the empty of the product, In response to this detection, Packaging machine Is empty Stopped not to make bags. In this packaging system, the packaging machine is stopped while avoiding contact between the sealer and the packaging material. , When the roller stops at a stop position that avoids contact with the packaging material The packaging machine It is preset to stop. And according to the stop position, the space | interval between the products transferred on an infeed conveyor is adjusted. Once this adjustment has been made, the product is transferred from the product transport device to the infeed conveyor with the spacing adjusted, even when the packaging system is in normal packaging operation. When the interval-adjusted product is fed from the infeed conveyor to the packaging machine, it is returned to an interval that matches a predetermined cut size. Therefore, it is possible to stop the sealer at a position where interference with the packaging material is avoided in accordance with the adjustment of the supply of the product, while making the crossing position of the product to the feeding conveyor unchanged.
[0011]
In this packaging system, the controller causes the stop position to pass through a sealing engagement position with the packaging material. In front Depending on the situation, the operating speed of the infeed conveyor is reduced with respect to the feeding speed of the packaging material. Speed To shorten the distance between the products delivered to the feed conveyor. Shrink Set to And by increasing the operation speed of the feed conveyor relative to the feed speed of the packaging material in response to the stop position after passing the seal meshing position with the packaging material, Set a larger interval between the products passed to the feed conveyor can do. When the stop position of the sealer is set to a position before the meshing position, the distance from the transition position to the feed conveyor to the tip of the packaging material is shortened, so that the transporter is sent to the feed conveyor via the transition position. For products, adjustments are made to reduce the product interval by slowing the operating speed of the infeed conveyor relative to the speed of the packaging material. Conversely, when the sealer stops at a position advanced from the meshing position, the distance from the crossover position to the feed conveyor to the leading edge of the packaging material becomes long. For products sent to the conveyor, adjustment is performed to increase the product interval by increasing the operating speed of the infeed conveyor relative to the feed speed of the packaging material. By changing the operating speed of the infeed conveyor relative to the packaging machine, that is, the infeed speed of the packaging material, operation can be performed without complicating the hardware configuration of the infeed conveyor by moving the product in and out relatively. As a countermeasure against control, the interval between products can be easily shortened or expanded as a countermeasure against product vacancy.
[0012]
In this packaging system, the controller includes a height of the product, a shape of the sealer, a distance from the transition position to a seal engagement position of the sealer, and a cut of a package in which the product is packaged in the packaging material. Based on the dimensions, the stop position of the sealer is calculated. That is, the controller calculates a stop position that can avoid contact with the packaging material during the operation cycle of the sealer when the packaging machine stops, and is shortened or expanded based on the stop position of the sealer. The interval between products can be calculated. The position of the sealer is determined based on the shape and operation cycle of the sealer, the distance from the crossover position to the seal engagement position of the sealer, and the cut dimensions of the bag package in which the product is packaged.
[0013]
In this packaging system, the packaging machine uses an end sealer that seals the sealer across the web-shaped packaging material at a position before and after the product, using the packaging material as a web-shaped packaging material formed into a tube shape. It can be set as a bag packaging machine. Examples of the bag packaging machine include a horizontal pillow packaging machine. By making the packaging material into a web-shaped packaging material formed into a tube shape, the product is fed into the web-shaped packaging material molded into a tube shape by an infeed conveyor. An end sealer as a sealer sandwiches a tubular web-shaped packaging material at a position between products and seals the packaging material.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of a packaging system according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic side view showing an embodiment of a packaging system according to the present invention, and FIG. 2 is an explanatory view for explaining the operation of product supply control by a controller in the packaging system shown in FIG.
[0015]
The packaging system shown in FIG. 1 includes a horizontal pillow type packaging machine 1 for packaging a product A by three-way sealing a tubular packaging material. The packaging machine 1 includes a former 2 that forms a web-like packaging film F as a packaging material into a tube shape, a center sealer 3 that performs center sealing on the packaging film F that is formed into a tube shape by the former 2, and a center seal. It comprises an end sealer 4 that seals the applied tubular packaging film in the transverse direction. In the illustrated example, the end sealer 4 is composed of a pair of upper and lower rotating heater blocks 4a and 4a that are heated to a high temperature by energizing a heating wire, and the heater blocks 4a and 4a enclose the tubular packaging film F in a seal. It welds by pinching in the position 5. The product A fed into the tube-shaped packaging film F with a certain distance D advances together with the packaging film F, and the packaging film F is sealed with the end sealer 4 before and after the product A, so that the inside of the packaging bag B. And the bag package P is manufactured.
[0016]
The product transporting apparatus 10 for supplying the product A to the packaging machine 1 has a first conveyor 11, a second conveyor 12, and a second conveyor 12 each consisting of a belt conveyor in order from the upstream side of the flow of the product A. It consists of an infeed conveyor 13 connected via A product passage sensor 14 that detects the passage of the product A is disposed between the first conveyor 11 and the second conveyor 12. The first conveyor 11 is a variable supply conveyor driven by a variable speed first drive motor M1, and the second conveyor 12 is a constant speed conveyor driven at a constant speed by a second drive motor M2 in accordance with the packaging speed. It is. The first conveyor 11 is usually operated at a speed lower than that of the second conveyor 12, and even when the products A are in contact with each other on the first conveyor 11 to which the products A are irregularly supplied, the driving speed is increased. When the product A is transferred to the fast second conveyor 12, the product A is surely cut off.
[0017]
The feeding conveyor 13 is driven by a servo motor M3. When the packaging system is operated in the mode for adjusting the stop position of the end sealer 4 according to the present invention, the servo motor M3 is operated in accordance with the operation of the packaging machine 1, as will be described later, in order to adjust the interval between the products A. Are controlled at different set speeds. Further, the feed roller 8 for feeding the web-like packaging film and the paper feeding roller 9 for feeding the laminated edge of the tube-like packaging film are packaging material feeding means for feeding the packaging film F. Both rollers 8, 9 are films. It is driven by a feed drive motor M4. Further, the end sealer 4 is driven by an end seal drive motor M5. In the illustrated example, a roller conveyor 6 driven in synchronization with the feeding speed of the packaging film F is connected between the feeding conveyor 13 and the tube-shaped film F as a packaging material. In 6, the interval between the products A is not adjusted.
[0018]
By detecting the passage (time) of the product A from the first conveyor 11 to the second conveyor 12 by the product passage sensor 14, the interval between the products A is measured. The controller 7 controls the drive of the drive motors M <b> 1 to M <b> 5 based on the detection signal input from the product passage sensor 14 to control the product supply control and the packaging machine 1. That is, if the interval between the products A matches the predetermined interval, the second conveyor 12 and the packaging machine 1 perform a normal operation. Try to cross the product A that has already crossed the second conveyor 12 and next. Product A When If the interval is less than the predetermined interval, 1 Conveyor 11 Is temporarily adjusted or decelerated to adjust the interval so that the product interval coincides with the predetermined interval. When the interval between the products A is larger than the predetermined interval, the packaging machine 1 (specifically, the film feed driving motor M4 and the end seal driving motor M5) and the feeding conveyor 13 following the packaging machine 1 are matched to the interval. The interval adjustment for returning to the predetermined interval is performed by temporarily stopping or decelerating. When the product A of the feed conveyor 13 is transferred from the second conveyor 12 through the crossing position 15 by this interval adjustment, the product A is supplied in a state of being aligned at a predetermined equal interval. The feeding conveyor 13 may be temporarily stopped or decelerated following the packaging machine 1 during operation.
[0019]
Prior to packaging, the controller 7 of the packaging system has data necessary for controlling the packaging machine 1 corresponding to the availability of the product, that is, the height H and length L of the product A and the product A are packaged. The cut size L1 of the bag package P, the rotation radius R of the end sealer 4, the distance L2 from the transition position 15 between the second conveyor 12 and the feed conveyor 13 to the seal engagement position 5 of the end sealer 4 and the like are taken in. It is out. When there is a large vacancy in the supply of the product A, the packaging machine 1 is stopped so as not to make an empty bag, and the supply of the product A is waited to resume, but the end sealer 4 comes into contact with the packaging film F at the stop position. Based on the above data, the stop position of the end sealer 4 is determined in advance so as not to stop in the state.
[0020]
The adjustment of the interval between the products A is shortened or enlarged depending on whether the stop position of the end sealer 4 is before or after passing through the seal engagement position 5 with the packaging film F. Is done. FIG. 2 is an explanatory diagram showing product supply control when the end sealer stops at the stop position before the seal engagement position in accordance with the product availability in the packaging system shown in FIG. FIG. 2 (a) shows that the end sealer 4 is welded by sandwiching the packaging film F at the meshing position 5 in the operation state where the interval between the products A is not adjusted, and the bag package P just manufactured is cut off. Shows the state. The feeding speed of the feeding conveyor 13 matches the feeding speed of the packaging film F.
[0021]
In FIG. 1, after the last product A is detected, when the product passage sensor 14 detects that the product A has not been detected for a predetermined time or more, the last product A is transferred to the feeding conveyor 13. When loaded, the packaging system is stopped. The end sealer 4 is stopped by avoiding contact with the packaging film F at a stop position in front of the seal engagement position 5 as shown in FIG. In this case, the movement amount of the packaging film F is smaller than that in the case of FIG. 2A, and the movement amount of the product A that moves in synchronization with the packaging film F is indicated by “−ΔL”. To decrease. If the infeed conveyor 13 is operated as usual, the interval between the product A already transferred to the packaging machine 1 and the product A transferred to the infeed conveyor 13 is abruptly and very narrow. Therefore, in accordance with the adjustment of the stop position of the end sealer 4, the interval between the products A transferred from the second conveyor 12 to the feeding conveyor 13 via the transition position 15 does not adjust the stop position of the end sealer 4. The distances D1 and D2 (D1 <D2) are shorter than the distance D in the case of.
[0022]
In order to shorten the interval D of the product A, the controller 7 sets the operation speed of the feeding conveyor 13 to a speed that is always reduced (speed multiplied by a constant ratio of less than 1) with respect to the feeding speed of the packaging film F. is doing. By reducing the operating speed of the feeding conveyor 13 with respect to the feeding speed of the packaging film F, the interval between the products A sequentially transferred to the feeding conveyor 13 can be shortened to the interval D1. In this way, the operation control (software) of the feed conveyor 13 reduces the drive speed of the feed conveyor 13 with respect to the feed speed of the film F without changing the hardware configuration such as the crossing position of the feed conveyor 13. Thus, it is possible to easily take measures against the empty space of the product A and the stop position of the end seal 4. When the product A that has been subjected to the interval adjustment is sent from the feed conveyor 13 to the packaging machine 1, the product A is returned to the predetermined interval D and sent. When the product passage sensor 14 detects that the supply of the product A by the first conveyor 11 and the second conveyor 12 has been resumed, the packaging is immediately started from the stop state at the timing when the product comes before the feed conveyor 13. Resumed. Even when the operation is resumed, the operation of the feeding conveyor 13 is performed while maintaining a state of being decelerated at a constant ratio with respect to the operating speed of the packaging machine 1, and is returned to the predetermined interval D when being fed into the packaging machine 1. It is. Therefore, the packaging machine 1 can continuously resume packaging of the product A according to the original cut dimensions without making an empty bag.
[0023]
FIG. 3 is an explanatory diagram showing product supply control when the end sealer stops at the stop position after the seal engagement position in accordance with the product availability in the packaging system shown in FIG. FIG. 3A shows an operating state in which the interval between the products A is not adjusted, as in FIG. In this example, when the vacancy of the product A is detected and the packaging machine 1 is stopped, the stop position of the end sealer 4 for avoiding contact between the end sealer 4 and the film F is as shown in FIG. In addition, it is set at the stop position advanced from the sealing engagement position with the packaging film F. In this case, the movement amount of the packaging film F is increased by forward rotation of the paper feed roller 9 or the like according to the advancement amount of the end sealer 4, thereby increasing than the case shown in FIG. The amount of movement of the product A that moves in synchronization with F also increases as indicated by ΔL. If the feeding conveyor 13 is operated as usual, the interval between the product A already transferred to the packaging machine 1 and the product A newly transferred to the feeding conveyor 13 becomes too rapid and very wide. . Therefore, in accordance with the adjustment of the stop position of the end sealer 4, the interval between the products A transferred from the second conveyor 12 to the feeding conveyor 13 via the transition position 15 does not adjust the stop position of the end sealer 4. In this case, the distance D3 is larger than the distance D.
[0024]
In order to increase the interval D of the product A, the controller 7 changes the operation speed of the infeed conveyor 13 to the packaging film F without changing the hardware configuration of the infeed conveyor 13 as in the case of shortening the interval D shown in FIG. The feed speed is always increased (speed multiplied by a constant ratio exceeding 1 time). By increasing the operation speed of the feeding conveyor 13 with respect to the feeding speed of the packaging film F, the interval between the products A sequentially transferred to the feeding conveyor 13 can be increased to the interval D3. In this case as well, measures against the empty position of the product A and the stop position of the end seal 4 can be obtained by software measures that reduce the drive speed of the feed conveyor 13 without changing the hardware configuration such as the crossing position of the feed conveyor 13. Can be done easily. When the product A having been subjected to the interval adjustment is fed from the feeding conveyor 13 to the packaging machine 1, the interval between the products A is shortened to a predetermined interval D. Regarding the resumption of packaging in accordance with the resumption of the supply of the product A, as in the previous embodiment, the operation of the feeding conveyor 13 is performed while maintaining a state where the speed is increased at a constant rate with respect to the operation speed of the packaging machine 1. It is returned to the predetermined interval D when it is fed into the packaging machine 1. Therefore, the packaging machine 1 can continuously resume packaging of the product A according to the original cut dimensions without making an empty bag.
[0025]
In the above embodiment, the end sealer 4 is a rotary heat sealer. However, instead of this, a sealer that performs box motion may be used, and a cutter that cuts and separates each bag package P together with a seal may be provided. it can. Further, the packaging machine 1 has been described by taking a horizontal pillow packaging machine as an example. However, the packaging machine 1 can be applied to a reverse pillow packaging machine that supplies a web-shaped packaging material from below and performs center sealing on the upper side, or a web-shaped packaging material. The present invention can also be applied to a drawing and packaging machine that draws a recess that contains a product and covers the recess that contains the product with another packaging material for sealing. The feed conveyor 13 is shown as having a length that allows only two products to be placed, but it is apparent that the length may be such that three or more products can be placed at the same time.
[0026]
【The invention's effect】
The present invention relates to a product conveyor having a transport conveyor on which a product passage sensor for detecting the passage of a product is arranged, a feed conveyor connected at a transfer position on the carry-out side, and a product fed at predetermined intervals by the feed conveyor. A packaging material feeding means for sending a packaging material for wrapping the product together with the product, a packaging machine having a sealer for sealing the packaging material for sealing the packaging material for wrapping the product, the feeding conveyor, and the packaging material feeding means And a controller for controlling the operation of the sealer, wherein the controller is arranged in advance in accordance with the stop position of the end sealer for avoiding contact between the sealer and the packaging material when the packaging machine is stopped. The spacing between products passed to is adjusted. Accordingly, the structure of the transfer conveyor, the feed conveyor, etc. is not complicated because it does not need to be changed from the conventional transfer conveyor and packaging machine. In addition, since it is possible to cope with software such as operation control, the transition position can be changed steplessly without adopting a complicated structure that allows the transition position to be changed like a shuttle conveyor or a split conveyor. Similar effects can be obtained. Therefore, a packaging system that avoids a situation such as melting of the packaging material due to the end sealer that is at a high temperature being in contact with the packaging material at the seal engagement position has a simple configuration and is inexpensive. Can be realized.
