Description

  The present invention relates to a pillow wrapping machine, and more specifically, to an apparatus for transporting a plurality of bar-shaped articles together, sequentially feeding them to a wrapping machine main body, and performing pillow wrapping there.

  Spaghetti, raw noodles, and other long noodles such as dry noodles can be transported in a bundled state, fed to the pillow wrapping machine main body at a predetermined interval, and processed for pillow wrapping there. is there. For example, there is an apparatus disclosed in Patent Document 1 as a conveying and supplying apparatus for a rod-shaped article provided in the previous stage of the pillow packaging machine body.

  The apparatus disclosed in Patent Document 1 includes an article conveying rod passage having a substantially U-shaped cross section with an open upper portion, and a feed plate that moves forward in the article conveying rod passage. The outer shape of the push plate coincides with the inner shape of the article conveying rod passage. As a result, when a large number of rod-shaped articles are filled and supplied into the article conveying rod passage, the pushing plate moved from the rear side hits the rear end of the rod-shaped article and is pushed forward as it is. Therefore, the rod-shaped article is conveyed at intervals of the arrangement pitch of the push plate and supplied to the next-stage pillow packaging machine body.

  In addition, there is a packaging machine using a conveyance supply device in which a conveyance surface that receives a rod-shaped article moves like a plate conveyor. This conveyance supply device is configured to include a plurality of plates arranged before and after constituting the conveyance surface, and a positioning plate arranged so as to protrude above the conveyance surface at regular intervals in the front-rear direction. The And many bar-shaped articles supplied on the conveyance surface comprised from this several plate are conveyed with a movement of a plate in the state which the rear end surface contacted the positioning plate. Therefore, a large number of bar-shaped articles are moved on the conveyance supply device at the arrangement pitch intervals of the positioning positions, and are sequentially supplied to the next packaging machine body (bag making machine). By using the transport and supply device using this plate conveyor, a large number of rod-shaped articles can be transported reliably and supplied to the packaging machine main body even in a disjointed state.

Japanese Utility Model Publication No.51-17190

  By the way, this kind of packaging machine sets the bottom face of the bag making machine to a lower position than the conveyance surface of the conveyance supply device. This is because the structure of the bag making machine cannot be extended to the plate conveyor side to fill the gap, so if the conveying surface of the carrying supply device and the bag making machine are flush with each other, the product will be under the bag making machine. May get in. In order to prevent this, the level of the bag making machine is lowered. However, the product is displaced due to the influence of the angular velocity due to the product following the revolving motion when the plate wraps around the return side or the slip due to the step.

  Further, among the plurality of rod-shaped articles, those located on the outer periphery that are in contact with the film receive contact resistance from the film and move at the same speed as the film, and those located at the center of the plurality of rod-shaped articles are There is little influence from the film, and it is greatly affected by the conveyance force from the conveyance supply device and the force that moves forward due to slippage due to a step. As a result, the plurality of bar-shaped articles are subjected to different conveyance speeds depending on the location, the rear ends are not aligned, and there is a possibility that the end seal device in the packaging machine body may be bitten. As a result, in particular, there is a problem that a phenomenon occurs in which the center of the plurality of rod-shaped articles moves quickly and the rear ends are not aligned.

In order to solve the above-described problems, the pillow packaging machine of the present invention (1) wraps a product composed of a plurality of rod-shaped articles with a packaging film formed in a cylindrical shape by a bag making machine, A pillow wrapping machine main body that seals and cuts a predetermined position for packaging, and is arranged upstream of the pillow wrapping machine main body, and transports the product with its longitudinal direction in the transport direction. A pillow wrapping machine that sequentially feeds and feeds, and moves up and down between a carry-out end of the transport and feed conveyor and the bag making machine provided on the carry-in side of the pillow wrapping machine body. a cross member which contacts away the lower surface of the product by the crossover device having a drive source for lifting the cross member is provided, the transport supply and the transition member by the driving of the drive source reaches the raised position Said transition member to a lower surface of the product during transfer to the bag unit is contacted by conveyors, the products wherein is released conveyed conveying force to said product by the supply conveyor is in the transport force from the pillow packaging machine main body When transported, the moving member is moved downward by the driving of the driving source so as not to contact the product.

  Since the crossover device is a crossover member that moves up and down, the configuration is simple and can be made compact. If the drive source that moves up and down is constituted by a cylinder as in the embodiment, not only the apparatus configuration can be reduced in size and simplified, but also control is facilitated. In particular, at the lowered position, the upper surface of the crossing member only needs to be in non-contact with the product, so it can be set roughly, and the raised position should be at a desired position in contact with the lower surface of the product, so that the cylinder rod protrudes most. The position of the upper surface at that time may be set so as to be the desired position, and the adjustment becomes easy.

  According to this invention, even if there is a certain distance from the front end of the conveyance surface of the conveyance supply conveyor to the bag making machine and there is a space between the two, the transition member is disposed in the space, and the transition member When is in the raised position, it can contact and support the lower surface (bottom surface) of the product, so that the product can be reliably transferred to the bag making machine side without falling in the space. In addition, in the raised position, it comes into contact with the lower surface (bottom surface) of the product to become a resistance, and a shift is prevented by applying a braking force to the product. Further, when the product does not receive the conveying force from the conveyance supply conveyor, the crossing member descends and comes into non-contact with the product, so that the conveyance of the product supplied into the bag making machine is not hindered.

Further, when the conveyance from the conveyance supply conveyor to the product is released (immediately before), the transition member is lowered. Thereby, since the transition member separates from the product, the transition member does not become a resistance factor with respect to the transport of the product, and can be transported smoothly.

  While the product is receiving the conveyance force from the conveyance supply conveyor, it is better that the transition member is in contact with the product and exerts a resistance force. For products that receive only the transfer force, it is better not to contact the crossover member. Therefore, when the conveyance force to the product by the conveyance supply conveyor is released, it is preferable that the moment when the conveyance force is released is actually just before.

  In particular, in the case of relatively lightweight articles such as dry noodles, contact resistance from a stationary member such as a transition member may also hinder smooth conveyance, and if the product length is long, contact Although the period during which the transfer is carried out becomes longer, the product can be smoothly conveyed on the pillow packaging machine body by being non-contacted at an appropriate timing when the conveyance force from the conveyance supply conveyor is released.

  On the other hand, if the transfer device is a belt conveyor (transfer belt), the transfer speed of the transfer belt does not become a resistance component by matching it with the transfer speed in the pillow packaging machine body, but the device becomes larger and transported. It is difficult to arrange in the narrow space between the supply conveyor and the bag making machine.

  (2) The transport surface, the upper surface of the transition member that has reached the raised position, and the bottom surface of the bag making device may be arranged flush with each other. In the present invention, by arranging the crossover member in the space between the transport supply conveyor and the bag making machine, the lower surface of the product unloaded from the transport supply conveyor is supported by the crossover member, so that it goes straight down as it is. It can be moved forward without any problems. Therefore, even if the bottom surface of the bag making machine is flush with the conveyance surface of the conveyance supply conveyor, the product can be reliably moved to the bag making machine side. And since the height of the conveyance surface of the conveyance supply conveyor and the bottom surface of the bag making machine becomes equal, the product in the middle of unloading from the trimming supply conveyor may slide down and the product may move faster than the conveyance speed of the conveyance supply conveyor. The product can be supplied to the bag making machine side at a desired timing and position.

  As described in the invention of (1) above, the transition member in the raised position is in contact with the lower surface of the product and exerts a braking force. It is also possible to take a setting to shift the height position of. In that case, preferably, the upper surface of the crossover member that has reached the ascending position is not more than the height of the transport surface of the transport supply conveyor, and more than the imaginary line connecting the front end of the transport surface to the bottom surface of the bag making machine. It is good to set so that it may be located in. If it is a position satisfying this condition, the bottom surface of the front end of the product protruding from the front end of the transport surface of the transport and supply conveyor can be securely and smoothly placed on the top surface of the crossover member at the ascending position and passed directly to the bag making machine. In addition, since the bridging member gives a certain level of braking force to the product, it is possible to suppress the product from slipping down and causing a shift even if there is a level difference (the bag making machine side is low).

  (3) The said conveyance supply conveyor can be used as the plate conveyor provided with the several plate arrange | positioned before and behind which comprises the said conveyance surface. In particular, in the case of a plate conveyor, when the plate reaches the front end of the transport surface, it rotates from there and changes its traveling direction and returns to the carry-in side. As the plate moves downward, the rear end of the product in contact with the plate tries to move downward as the plate moves. However, in the present invention, the crossing member is in contact with the lower surface of the product, and the downward movement is suppressed. Is done. Therefore, the product is supplied at the original transport speed of the transport and supply conveyor without the speed increase associated with the downward movement, and the product is transferred to the bag making machine side with the tips (rear ends) of the multiple rod-shaped articles aligned. Can do.

  (4) On the premise of the invention of (3) above, the transport supply conveyor includes a positioning plate arranged so as to protrude above the transport surface at regular intervals in the front-rear direction. Furthermore, a positioning device is provided that includes a positioning pusher that contacts the front surface of the product being transported, and a moving means that moves the positioning pusher. Then, the moving means is configured to move the rear surface of the product so as to be positioned by contacting the rear positioning plate by biasing relatively rearward in contact with the front surface of the product. Good. By adopting such a configuration, the rear end position of the product can be surely aligned in the middle of the conveyance, and can be supplied to the pillow packaging machine body as it is. When the conveyance force to the product by the conveyance supply conveyor is released, the positioning plate is separated from the product.

  (5) On the premise of the invention of the above (3) or (4), a side guide device for regulating the lateral width on the transport surface is provided, and the side guide devices are respectively arranged on the left and right on the transport surface, A circulating side guide member (corresponding to the side guide plate of the embodiment) and means for moving the plurality of side guide members forward in synchronization with the movement of the transport surface (endless chain 12 or the like) may be provided. In this case, the lower end of the side guide member plate may be configured to come into contact with the transport surface, or may be configured to protrude below the transport surface. By moving the side guide member, the product can be smoothly conveyed on the conveyance supply conveyor.

  By the way, the conveyance supply apparatus disclosed in Patent Document 1 has a constant shape of the article conveyance rod passage, and the conveyance width cannot be changed. In the present invention, the conveyance width cannot be changed as described above, or the conveyance width can be changed as shown in the embodiment. However, when a product having a constant transport width is used, for example, if the number of a group of long bar-shaped articles to be transported is reduced, the height of the group of long bar-shaped articles is reduced, and it is difficult to push with a feed plate.

  Further, since the width of the article transporting saddle passage is constant, the lateral width of the bag making machine of the next-stage pillow packaging machine main body corresponds to the width of the article transporting saddle passage and is fixed. Therefore, the cylindrical film that is shaped into a cylindrical shape by the bag making machine also has a uniform horizontal width, and the group of long rod-shaped articles that are reduced in number has a flat shape with a small height ratio to the horizontal width. For this reason, the package that is manufactured is also flattened and looks bad. Accordingly, there is a problem that it is desired to transport the product in an appropriate state / form in accordance with the total amount of the long bar-shaped articles.

  (1) Therefore, in order to change the conveyance width, the conveyance supply conveyor is configured to convey a product composed of a plurality of bar-shaped articles with the longitudinal direction thereof directed in the conveyance direction, and the conveyance surface of the conveyor device. A side guide device that regulates a lateral width of the plurality of side guide plates that are arranged on the transport surface on the left and right sides, respectively, and a plurality of side guide plates that circulate, and the plurality of side guide plates that move the transport surface. Means for moving forward in synchronism with each other (endless chain 12 or the like) and means (handle or the like) for moving at least one of the left and right side guide plates in a direction crossing the conveying direction. It is good to comprise so that the lower end of a guide plate may contact the said conveyance surface.

  In this way, the lateral position of the side guide plate can be changed. Therefore, when the amount (number) of the rod-shaped articles constituting the product to be conveyed is large, the side guide plate is moved outward in the traveling direction. The space between the side guide plates (the width of the conveying surface) can be widened to prevent the product from becoming unnecessarily bulky. In addition, when the amount of a plurality of articles constituting the product is small, the side guide plate is shifted to the center to reduce the distance between the two, so that the product spreads sideways and the volume is low and flat. Without any problem, the aspect ratio can be made appropriate.

  Further, since the lower end of the side guide plate is in contact with the conveyance surface, the load of the side guide plate is supported by the conveyance surface, so that the drive mechanism (such as an endless chain in the embodiment) that moves the side guide plate is used. On the other hand, an excessive load is not applied downward. Therefore, the problem of extension of the endless chain or the like can be suppressed as much as possible, and can be realized and handled with a simple configuration even if the overall length of the transport device is increased. Furthermore, since the lower end of the side guide plate is in contact with the conveyance surface in this way, even if there is no gap or a partial / temporary gap is generated, there are very few and a plurality of pieces that are in contact with one product. Since all of the side guide plates are not greatly separated from the contact surface at the same time, it is possible to suppress the product from entering the gap as much as possible. Furthermore, since the side guide plate is moved in contact with the conveying surface, no foreign matter is generated due to wear.

  In addition, the lower end of the side guide plate that rotates in this way can be protruded downward from the conveyance surface instead of contacting the conveyance surface. In this case, the side guide plate is positioned outside the plate, and in order to prevent the product from falling from the side, the width of the conveyance surface is appropriately widened in the front and rear, and the side guide plate is provided in a narrow portion. Insert the bottom edge. As a result, the side guide plates are not arranged back and forth, but are arranged discretely, the movement of the rod-shaped article in the width direction is restricted by the side guide plates, and the downward drop is a wide part ( It can be regulated by protruding outside the side guide plate). Further, although referred to as a side guide plate, it is not limited to a flat plate, and may be a rod-shaped body.

  (2) ′ The conveyor device is a plate conveyor, and is arranged so as to protrude above the conveyance surface at regular intervals in the front-rear direction, with a plurality of plates arranged before and after the conveyance surface. It is good to provide the positioning plate made. If it does in this way, a product can be conveyed at a fixed interval back and forth by making a product contact a positioning board. The positioning plate may have a dimension and shape that contacts the entire front end (rear end surface in the embodiment) of the product.

  (3) ′ The side guide plate that moves in the direction intersecting the transport direction is not installed at least at the position where the positioning plate is formed. In this way, even if the side guide plate moves in the direction crossing the transport direction, it does not interfere with the positioning plate within the moving range. Therefore, it is possible to use the same positioning plate even if the side guide plate is moved and the width is adjusted by making the dimensional shape of the positioning plate correspond to the maximum width between the pair of side guide plates. Can be exchanged.

  (4) 'Based on the inventions of (2)' and (3) 'above, an alignment device is provided above the conveyor device, and the alignment device contacts the front surface of the product in the middle of conveyance. A positioning pusher and a moving means for moving the positioning pusher, and the moving means biases the rear surface of the product rearward while being in contact with the front surface of the product. It is good to move so that it may contact and position a positioning board. If it does in this way, the space | interval of the product before and behind conveyed can be arrange | equalized reliably for every fixed space | interval.

  (5) Based on the invention of (4) above, a space is formed behind the positioning plate without providing a plate constituting the plate conveyor, and the moving means is a lower end of the positioning pusher. However, it is better to enter the space. If it does in this way, a positioning pusher can be made to contact completely to the lower side of a product, and it can position by energizing back.

  (6) ′ On the premise of the above (4) ′ or (5) ′, the moving means moves the positioning pusher in the section where the positioning pusher is in contact with the product and urges backward. It may be controlled to move forward at a speed slower than the moving speed of the positioning plate. If it does in this way, since it can position while moving forward without pushing back a product back, it can control that the product contacts a positioning board with excessive force.

  (7) ′ A product supply device for supplying a product on the transport surface is provided above the conveyor device, and the product supply device includes a bottom plate that opens and closes, and a guide member that partitions an upper space of the bottom plate, The guide member has at least a guide portion provided above the side guide plate, and the guide portion located above the side guide plate that moves in a direction intersecting the transport direction moves the side guide plate. It is good to move following. In this way, when the product is placed on the bottom plate, the bottom plate is opened at a certain timing so that the supply to the transport surface can be performed smoothly. In addition, since the guide portion (side guide rod 36 of the embodiment) that regulates the width in the horizontal direction moves in the horizontal direction according to the guide plate, it can be supplied uniformly over the entire width direction of the transport surface. Become.

  (8) Based on the above invention (7) ', the bottom plate is a pair of bottom plates that open to the left and right, and the open state may be constant regardless of the position of the moving guide portion. If it does in this way, the drive mechanism and control for opening and closing a baseplate can be simplified.

  A long stick-shaped article such as dry noodles can be smoothly conveyed and supplied to the pillow packaging machine body. In addition, a product composed of a plurality of long articles can be transferred while maintaining a beautiful state.

  1 and 2 show an overall view of a preferred embodiment of a pillow packaging machine according to the present invention. The pillow wrapping machine 1 is disposed on the upstream side of the pillow wrapping machine main body 3 and the pillow wrapping machine main body 3 for pillow wrapping a product 2 to be packaged made of a large number of long rod-shaped articles such as dry noodles and spaghetti, A transport and supply device 4 that transports the product 2 forward and backward at a predetermined interval and sequentially supplies the product 2 to the pillow packaging machine body 3, and a transition device that is mounted between the pillow packaging machine body 3 and the transport and supply device 4 5 is provided.

  3 to 6 show the carry-out side / transfer device 5 of the conveyance supply device 4 and the carry-in side of the pillow packaging machine body 3 in an enlarged manner. The conveyance supply device 4 conveys a product 2 to be packaged made of a large number of long rod-shaped articles such as dry noodles and spaghetti, with a predetermined interval in the front and rear directions and a longitudinal direction in the conveyance direction. This is sequentially supplied to the packaging machine body 3. In addition, a large number of long bar-shaped articles that are products 2 of the present embodiment are in a state in which a plurality of long bar-shaped article bundles 2a that are bundled with a tape every predetermined number are arranged. Of course, instead of using the long rod-shaped article bundle 2a in this way, all of them may be separated (rose noodles).

  The pillow wrapping machine body 3 has a bag making device 3a arranged at the carry-out side end of the conveyance supply device 4, and an original fabric roll 3b arranged below the conveyance supply device 4, and continuously from the original fabric roll 3b. The fed strip-shaped film 3c is supplied to the bag making machine 3a, where the bag is formed into a cylindrical shape. Since the product 2 carried out from the conveyance supply device 4 is supplied into the bag making machine 3a at every predetermined interval, it is stored in a belt-like film that is formed into a cylindrical shape. The pillow packaging machine main body 3 has each component such as a center seal device and an end seal device disposed downstream of the bag making machine 3a.

  The main conveyance conveyor 10 which comprises the conveyance surface which conveys the product 2 consists of a plate conveyor. That is, a pair of endless chains 12 that rotate in a vertical plane are arranged on both the left and right sides of the conveyance supply device 4 in the conveyance direction. The pair of endless chains 12 are stretched over the sprockets 11 and 11 ′ disposed at both front and rear ends of the transport and supply device 4, and obtain a driving force from the front end side sprocket 11 linked to the driving motor 13, so as to be integrated. Rotate. And many strip | belt-shaped plates 15 are attached so that it may span between both the endless chains 12. FIG. In the example shown in the figure, a pair of sprockets 11 and 11 'are arranged at the front and rear ends. However, in this embodiment, since the overall length of the transport device is increased, the endless chain 12 is engaged with an appropriate intermediate position. Does not interfere with sprocket placement. In addition, the driving force is limited to the front end side sprocket 11, but this may also be applied to the rear end side sprocket 11 ′, or when an intermediate sprocket is provided, A driving force may be applied.

  The plate 15 has an elongated shape extending in a direction perpendicular to the conveying direction, and as shown in an enlarged view in FIG. 7, a predetermined number (n) are arranged side by side without any gaps, and a bottom of a certain area is formed. Configure the transport surface that does not strike. Further, if n plates 15 are arranged continuously in front and rear, a layout in which n plates 15 are continuously arranged again after a predetermined length without attaching the plates 15 by a predetermined length. take. As a result, as shown in FIG. 7, a predetermined space K is formed in front of and behind the group of plates 15 continuous for n sheets.

  Further, the total length of the entire n plates 15 is shorter than the total length of the product 2. Thereby, in the state which put the product 2 on the conveyance surface which consists of n plate 15, the end of the product 2 will be located in the space K (refer FIG. 8). Of course, setting the length of the product 2 to be longer in this way is not indispensable, the length of the both may be the same, or conversely, the length of the product 2 may be shorter (however, the noodles are aligned) If there is no equipment).

  As shown in FIG. 9B, the individual plates 15 are connected to the endless chain 12 with both ends of the plate 15 supported on L-shaped metal fittings 17 attached to the endless chain 12. It is done by fastening and fixing with a nut. Thereby, the plate 15 is integrated with the endless chain 12. Therefore, since the plate 15 constituting the conveying surface moves forward with the rotation of the endless chain 12, the product 2 supplied and placed on the plate 15 is conveyed forward with the forward movement of the plate 15. The

  Further, an L-shaped positioning plate 16 is disposed on the rear side in the traveling direction of the n consecutive plates 15. The positioning plate 16 has a shape including an upright vertical wall portion 16a and a substrate portion 16b extending from the lower end of the vertical wall portion 16a toward the rear in the traveling direction. As shown in FIG. 9A and the like, this positioning plate 16 has a bearing guide portion 18 attached to both ends of the lower surface of the substrate portion 16b, and the bearing portion 18a of the bearing guide portion 18 is connected to the inner surface of the endless chain 12. A support pin 19 provided so as to protrude toward the front is mounted. As a result, the bearing guide 18 and the positioning plate 16 connected to the bearing guide 18 can be rotated around the support pin 19. The lower surface of the bearing guide portion 18 becomes the guide surface 18b, and the guide surface 18b is in contact with the guide rails 20 arranged below the bearing guide portion 18 in a predetermined manner. In the contacted state, the rotation of the bearing guide portion 18 is restricted, and the positioning plate 16 maintains the state in which the vertical wall portion 16a stands.

  On the other hand, since the support is lost when the positioning plate 16 (guide surface 18b) reaches the area where the guide rail 20 is not installed, the vertical wall portion 16a of the positioning plate 16 is tilted backward in the traveling direction with the support pin 19 as the center. Rotate. By changing the posture in this way, the distance between the carry-out side end of the conveyance supply device 4 and the next-stage pillow packaging machine body 3 (bag making machine 3a) can be reduced.

  In the present embodiment, a side guide device 24 that regulates the lateral width of the transport surface is provided. The side guide device 24 is a device that adjusts the lateral width of the conveyance path constituted by a large number of plates 15. As shown in FIG. 2 and the like, the side guide device 24 is horizontally flat on sprockets 25 and 25 ′ provided at the front and rear end positions of the transport supply device 4 on the left and right outer sides of the transport path formed by the plate 15. The endless chain 26 that rotates inside is looped over. As shown in FIGS. 10 and 11, one end of a horizontal support plate 27 is connected to the endless chain 26, and a side guide plate 28 is attached to the other end of the horizontal support plate 27 so as to extend downward. A predetermined number of side guide plates 28 and horizontal support plates 27 are continuously arranged in the front and rear to form one group, and an unformed region is provided between the front and rear groups. Specifically, the side guide plate 28 is formed so that the side guide plate 28 is located in a region that is substantially the same (slightly narrow) as the region where the continuously arranged plates 15 are formed, and the side guide plate 28 is also formed in the region where the plate 15 is not formed. The setting is not provided. Of course, the side guide plate 28 is provided in a narrower range than the illustrated region with respect to the formation region of the plate 15, or completely coincides with the formation region of the plate 15. A guide plate 28 may be provided. Further, coupled with the fact that the product 2 is a long rod-shaped article, the side guide plate 28 is not necessarily limited to the one continuously disposed in the front and back without any gap, and the side guide plate 28 disposed in the front and rear is spaced. May be arranged.

  Further, the lower end of the side guide plate 28 is in contact with the surface of the plate 15. Moreover, the speed at which the side guide plate 28 and the plate 15 move forward is set to be the same. As a result, the side guide plate 28 moves forward in synchronization with the plate 15, and the lower end of the side guide plate 28 is in contact with the plate 15, so that the load of the side guide plate 28 is supported by the plate 15 and is endless. Even if a downward load is not applied or applied to the chain 26, it is small. Further, since the horizontal support plate 27 moves on the receiving rail while sliding on the return side, the loads of the horizontal support plate 27 and the side guide plate 28 are supported by the receiving rail. Therefore, the slack of the endless chain 26 can be suppressed, and even if the entire length of the transport and supply device 4 is long, one end can be configured with one endless chain 26 (a plurality of short endless chains are arranged in a straight line. No need to do).

  Since the pair of left and right side guide plates 28 are arranged on the plate 15, the product 2 supplied and transported on the plate 15 is placed in the space between the side guide plates 28 on the plate 15. Fits in. That is, the lateral width of the transport surface is determined by the distance between the pair of side guide plates 28.

  Cover cases 29 are disposed to cover the side guide plates 28, the horizontal support plates 27, the endless chain 26, the sprockets 25 and 25 ', and the like disposed on the left and right sides, respectively. The left and right cover cases 29 have opposite surfaces, that is, side surfaces on the transport surface 10 side, and the surface of the side guide plate 28 is exposed from the opening surface, thereby suppressing the lateral movement of the product 2. And the width of the conveying surface is restricted.

  This cover case 29 is integrated with the side guide plate 28, the horizontal support plate 27, the endless chain 26, the sprockets 25 and 25 ', and the like, and is movable in the lateral direction. That is, as shown in FIG. 6 and the like, each cover case 29 is linked to a power transmission mechanism 31 including a screw screw rotated by the operation handle 30, and when the handle 30 is rotated forward and backward, the cover cases 29 approach and separate from each other. Thereby, the space | interval between both the side guide plates 28 is changed, and the horizontal width used as the conveyance surface of the product 2 can be adjusted. 10 and the like show a state in which the side guide plate 28 is located near both ends of the plate 15 and the side guide plate 28 is separated (maximum lateral width), and in FIG. 5 and the like, the side guide plate 28 moves to the center. This shows a state where the width is narrowed.

  Thus, since the conveyance supply apparatus 4 of this embodiment can change the horizontal position of a pair of side guide plate 28, when there is much quantity of the elongate bar-shaped articles which comprise the product 2 to convey, a side guide plate 28 can be moved outward in the traveling direction to increase the distance between the pair of side guide plates 28 (the lateral width of the conveying surface), thereby preventing an unnecessarily high bulk. On the other hand, when the amount of the elongated bar-shaped article constituting the product 2 is small, the side guide plate 28 is shifted to the center to reduce the distance therebetween. Thereby, the product 2 can be in a state where the aspect ratio is appropriate without spreading horizontally and being flat and low in level. Of course, the adjustment of the position of the side guide plate 28 is not limited to the amount based on the amount of the thin rod-shaped article, and can be performed according to the form of the package to be finally produced.

  Further, in this embodiment, the left and right side guide plates 28 are moved closer to and away from each other by operating the handle 30, and the distance from the center to both the side guide plates 28 is made equal, but each moves independently. It may be possible, or only one of them may be moved.

  As shown in FIGS. 1 and 2, an article supply device 35 is disposed at an upper position in the vicinity of the upstream side of the conveyance supply device 4. As shown in FIG. 12 to FIG. 16, the packaged article supply device 35 is a product constituted by a pair of left and right bottom plates 43 that open and close, and a guide member that partitions the upper space of the bottom plate 43 into a rectangular shape. 2 temporary storage units, and a drive mechanism for moving the bottom plate 43 and a predetermined guide member in the horizontal direction. Then, by moving the bottom plate 43 in the horizontal direction at an appropriate timing to open the bottom, the articles to be packaged stored in the temporary storage unit are naturally dropped and moved to a predetermined position of the main conveyor 10 located below. To supply.

  The bottom plate 43 is disposed on both the left and right sides of the main conveyor 10, and has a plurality of bottom plate pieces 43a formed in a comb shape so as to extend from the left and right side ends toward the center in a horizontal plane, and a base end side ( A connecting plate 43b that is erected upward on the outer side of the main conveyor 10. The bottom plate pieces 43a of the pair of bottom plates 43 are arranged in the same straight line, and when both the bottom plates 43 are close to each other, the tips 43a 'of the bottom plate pieces 43a are close to each other (see FIG. 15 and the like). Further, as shown in an enlarged view in FIG. 15, the lengths of the bottom plate pieces 43a are alternately changed, so that the positions of the tips 43a 'of the opposed bottom plate pieces 43a are alternately shifted left and right. As a result, since the leading ends 43a 'are not in the same straight line, even if the article constituting the product 2 is a very thin rod-like article such as rose noodles, the pair of bottom plates 43 (bottom plate pieces 43a) approach each other. Even if the bottom plate 43 starts to separate and the tip 43a 'of the bottom plate piece 43a is separated, the elongated rod-shaped article 2a constituting the product 2 is not Since it is supported by the bottom plate piece 43a, it does not fall immediately. Then, when the tip 43a ′ of the bottom plate piece 43a is wide open at the time and the bottom plate 43 is completely opened, the elongated bar-shaped article 2a is dropped and supplied onto the main conveyor 10 located below.

  In this way, the elongated bar-shaped article does not fall until the tip 43a 'of the bottom plate piece 43a is separated to some extent. Therefore, when a gap is generated when the distal ends 43a' are slightly separated from each other, the elongated bar-shaped article tries to fall from the gap. Are concentrated in the center and are not clogged, or the central side is concentrated on the main transport conveyor 10 so that it does not rise into a mountain shape. Therefore, the elongated rod-shaped article is smoothly dropped and supplied to the plate 15 of the main conveyor 10 in the width direction.

  The drive mechanism for reciprocating the bottom plate 43 in the horizontal direction uses a cylinder 40. That is, the cylinder 40 is fixed to the mounting plate 41 erected at a predetermined position on the upper surface of the base plate 37a. A first connecting member 37b extending in a vertical direction is attached to a predetermined position on the lower surface of the pedestal plate 37a, and a second connecting portion is provided between the lower portion of the inner side surface of the first connecting member 37b and the machine frame 42 of the transport and supply device 4. It connects with the member 37c. Thereby, the base plate 37a is fixed to the machine casing 42. A connecting rod 40b is attached to the tip of the cylinder rod 40a of the cylinder 40 fixedly supported on the base plate 37a, and is fixed to the connecting plate 43b of the bottom plate 43 at the tip of the connecting rod 40b. Thereby, following the reciprocating movement of the cylinder rod 40a accompanying the operation of the cylinder 40, the bottom plate 43 also moves forward and backward toward the center and approaches and separates from each other.

  Furthermore, in this embodiment, in order to perform a forward / backward movement toward the center of the bottom plate 43 accompanying the operation of the cylinder 40 in a stable posture, two guide rails 48 are parallel to the movement direction in parallel with a predetermined direction. Place them at a distance. Further, a movable slider 49 is attached to the guide rail 48, and the slider 49 and the connecting plate 43b of the bottom plate 43 are connected using an L-shaped metal fitting 49a. As for the attachment position with respect to the connection plate 43b, the connection rod 40b linked to the cylinder 40 is attached at the center, and the L-shaped metal fittings 49b are attached to both ends.

  Further, in the present embodiment, as described above, the width of the conveyance surface (conveyance path) on the main conveyance conveyor 10 can be adjusted by the side guide plates 28 approaching and separating from each other. Reciprocally move regardless of the width. That is, the pair of bottom plates 43 is set so as to be able to be opened widely in accordance with the maximum width of the conveyance path. Thereby, the drive system for opening and closing the bottom plate 43 can be realized with a simple cylinder, and the control and configuration can be simplified.

  On the other hand, the guide member that partitions the upper space of the bottom plate 43 into a rectangular shape includes a fixed positioning guide plate 45 disposed on the front side in the transport direction, a moving positioning guide plate 46 disposed on the rear side in the transport direction, and sides disposed on both sides in the transport direction. And a guide rod 36. The movement positioning guide plate 46 moves forward and backward along the transport direction. As a result, as shown by the solid line in FIG. 13, the moving positioning guide plate 46 is moved backward to make the distance from the fixed positioning guide plate 45 sufficiently longer than the entire length of the product 2, thereby making the product 2 relatively rough. It becomes possible to supply to. Then, after the product 2 is supplied onto the bottom plate 43, the cylinder 47 is operated to move the moving positioning guide plate 46 forward (see the two-dot chain line in FIG. 13). As a result, a large number of long rod-shaped articles constituting the product 2 are pushed forward by the moving positioning guide plate 46 and positioned in the front-rear direction in the space between the moved moving positioning guide plate 46 and the fixed positioning guide plate 45. Made.

  Further, the side guide bar 36 is disposed so as to penetrate from the lower side to the upper side of the bottom plate 43. Specifically, the side guide bar 36 is inserted and disposed in a space between the front and rear bottom plate pieces 43a. That is, a plurality of side guide bars 36 are installed on one side. Each side guide rod 36 includes a main body portion 36a extending vertically upward from the bottom plate 43, and an inclined portion 36b that is connected to the upper portion of the main body portion 36a and is inclined outward. The lower ends of the main body portions 36a of the plurality of side guide bars 36 are connected to a connection plate 39 having a substantially U-shaped plane. The connecting plate 39 extends outward in the horizontal direction, and is fixed to the top surface 29a of the cover case 29 of the side guide device 24 at the tip side. The side guide bar 36 (main body portion 36 a) is installed above the side guide plate 28.

  Accordingly, even if the handle 30 is operated and the position of the side guide plate 28 is moved to the left and right, the side guide bar 36 integrated with the cover case 29 also moves to the left and right following the movement. For example, as shown by the solid line in FIG. 16, when the side guide plate 28 is located outside, the side guide bar 36 is also located outside, and the side guide plate 28 is located as shown by the two-dot chain line in FIG. When located on the center side, the side guide bar 36 is also located on the center side.

  The side guide bar 36 restricts the lateral movement of the elongated bar-shaped article constituting the product 2 stored on the bottom plate 43. Therefore, the horizontal width of the storage space for the product 2 temporarily stored on the bottom plate 43 and the horizontal width on the plate 15 regulated between the side guide plates 28 substantially coincide with each other in the width dimension and the arrangement position. When the bottom plate 43 is opened, the stored product 2 is smoothly transferred onto the plate 15 as it is.

  By the way, the movement of the main conveyor 10 and the timing of opening the bottom plate 43 are performed when the area between the front and rear positioning plates 16 provided on the main conveyor 10 is located below the bottom plate 43. Then, in order to prevent the dropped product 2 from hitting the upper end of the positioning plate 16 and not being supplied to the desired position, the product 2 is adjusted so as to drop to a position where there is a margin with respect to the front and rear positioning plates 16. The Therefore, the position of the product 2 conveyed on the main conveyance conveyor 10 in the front-rear direction varies, and cannot be supplied to the next-stage bag making machine 3a at a constant interval.

  Therefore, an alignment device 50 is provided in the middle of the main conveyor 10, and the rear end of the product 2 is positioned rearward by contacting the front end of the product 2 in the middle of conveyance and biasing it relatively backward. The plate 16 is brought into contact with the positioning. The specific configuration of the alignment device 50 is as shown in FIG.

  That is, the alignment device 50 includes a positioning pusher 51 that moves along a predetermined locus, and the positioning pusher 51 enters the space K between the front end surface of the product 2 and the positioning plate 16 positioned in front of the positioning pusher 51. As the product 2 moves forward, the positioning pusher 51 comes into contact with the entire end surface of the product 2 and urges it backward. Then, by gradually reducing the distance between the positioning pusher 51 and the positioning plate 16 positioned on the rear side of the product 2, the product 2 is finally sandwiched between the both 16 and 51, and the rear end of the product 2. Is positioned in contact with the rear positioning plate 16. Further, in order to reduce the impact received by the product 2 when the product 2 is sandwiched between the two parts 16 and 51, the positioning pusher 51 advances at a speed slower than the moving speed of the product 2 at least after contacting the product 2. I try to move. A drive mechanism for performing such an operation is as follows.

  First, an arm 52 that rotates forward and backward within a predetermined angle range with a rear end 52a as a rotation center is provided. A guide race 52 is fixed to a side surface of the arm 52 with a screw, and a slider 54 is movable on the guide rail 53. Attach to. A positioning pusher 51 is attached to the slider 54. As a result, when the arm 52 rotates forward and backward about the rear end 52a, the slider 54, and thus the positioning pusher 51, moves up and down. When the slider 54 reciprocates along the guide rail 53, the positioning pusher 51 also moves along the transport direction. Move back and forth. The positioning pusher 51 can be moved along a desired trajectory by performing this up / down movement and forward / backward movement at an appropriate timing.

  A link and a cam are used to reciprocate the slider 54 along the guide rail 53. That is, one end of the first connecting rod 56 is connected to the upper end 54 a of the slider 54, and the other end of the first connecting rod 56 is connected to the upper end 57 a of the first lever 57. The first lever 57 is linked to the rotation shaft 59 at the lower end, and rotates forward and backward within a predetermined angle range with the rotation shaft 59 as the rotation center. As a result, the first lever 57, the first connecting rod 56, and the slider 54 form a link mechanism. When the first lever 57 rotates forward and backward, the tip of the first connecting rod 56, that is, the slider 54 moves forward and backward. To do.

  As an example, as shown in FIG. 18 (a), when the first lever 57 is tilted forward in the traveling direction, the first connecting rod 56 is also positioned forward, so that the slider 54 and thus the positioning pusher connected thereto is arranged. 51 is also located forward. From this state, when the first lever 57 rotates counterclockwise in the drawing and falls to the rear side in the traveling direction, the first connecting rod 56 is also pulled back as shown in FIG. As a result, the positioning pusher 51 moves backward.

  The forward / backward movement of the slider 54 is guided along the guide rail 53 and stably performed along the arm 52. Further, the forward / reverse rotation of the first lever 57 is caused by a disc-shaped first cam floor 58 provided with a first cam floor 58 attached to an intermediate point of the first lever 57 and a cam groove 71a in which the first cam floor 58 is linked. It is controlled by a cam mechanism with a single plate cam 71. That is, when the first plate cam 71 rotates, the distance from the center of the cam groove 71a where the first cam floor 58 coincides changes, so that the first lever 57 rotates with the change.

  In addition, the arm 52 has a rotational axis linked to the rear end 52a, and a bar 62 is connected to the rotational axis. As a result, the arm 52 and the bar 62 are integrated to form an L shape. One end of the second connecting rod 63 is connected to the tip of the bar 62, and the other end of the second connecting rod 63 is connected to the upper end 64 a of the second lever 64. The second lever 64 is linked to the rotation shaft 59 at the lower end, and rotates forward and backward within a predetermined angle range with the rotation shaft 59 as the rotation center. As a result, the second lever 64, the second connecting rod 63, the bar 62, and the arm 52 constitute a link mechanism. When the second lever 64 rotates forward and backward, the arm 52 has the rear end 52a as the center of rotation. Rotate forward and backward within a predetermined angle range.

  As an example, in the state where the second lever 64 is tilted forward in the traveling direction as shown in FIG. 18, the first connecting rod 63 is also positioned forward, so that the lower end of the bar 62 is pushed forward, The integrated arm 52 is in a state where the front end is lifted around the rear end 52a. From this state, when the second lever 64 rotates counterclockwise in the figure and falls to the rear side in the traveling direction, the second connecting rod 63 is also pulled back as shown in FIG. As a result, the lower end of the bar 62 also moves rearward, and the arm 52 integrated therewith rotates clockwise about the rear end 52a and the front end is lowered. Thereby, the positioning pusher 51 attached to the arm 52 moves up and down.

  The forward / reverse rotation of the second lever 64 is caused by a disk-shaped first cam provided with a second cam floor 65 attached to an intermediate point of the second lever 64 and a cam groove 72a in which the second cam floor 65 is linked. The cam mechanism is controlled by a two-plate cam 72. That is, when the second plate cam 72 rotates, the distance from the center of the cam groove 72a where the second cam floor 65 coincides changes, so that the second lever 65 rotates forward and backward with the change.

  Then, by appropriately setting the shape (trajectory) of the upper groove 71a of the first plate cam 71 and the cam groove 72a of the second plate cam 72, the forward / backward movement and the vertical movement of the positioning pusher 51 are independent of each other. As a result, the positioning pusher 51 moves along a desired locus as shown below, and the product 2 can be positioned. First, as shown in FIG. 18A, both the first lever 57 and the second lever 64 are located at the front position, the slider 54 is located at the distal end side of the arm 52, and the distal end of the arm 52 is raised. Is the reference posture. In this reference posture, the positioning pusher 51 is positioned upward and forward. Therefore, the positioning pusher 51 does not interfere with the product 2 and the product 2 moves forward as the main transport conveyor 10 is transported.

  From this state, as shown in FIG. 18B, when the first lever 57 rotates counterclockwise and the first lever 57 reaches the rear position, the positioning pusher 51 also moves rearward. At this time, since the second lever 64 remains in the reference posture, the positioning pusher 51 moves backward while moving slightly downward along the arm 52 where the inclination is inclined. However, in this state, the lower end of the positioning pusher 51 is positioned above the product 2 so as not to interfere with the transport of the product 2.

  Next, as shown in FIG. 19A → FIG. 19B → FIG. 20A, as the second lever 64 rotates counterclockwise, the arm 52 also rotates clockwise and the tip of the second lever 64 gradually increases. To descend. Therefore, the positioning pusher 51 gradually moves downward and enters the space between the front and rear products 2. At this time, since the main transport conveyor 10 is also operated and transported, the product 2 moves forward, so that the product 2 and the positioning pusher 51 gradually approach each other.

  Then, as shown in FIG. 20A, when the positioning pusher 51 is moved down to a position facing the front surface of the product 2, the first lever 57 is rotated clockwise, and the slider 54 and then the positioning pusher 51 are rotated. Is moved forward (see FIG. 20A → FIG. 20B → FIG. 21A). At this time, the speed at which the positioning pusher 51 moves forward is set slower than the moving speed of the product 2, so that the distance between the positioning pusher 51 and the front surface of the product 2 is gradually reduced. Since the product moves forward at a moving speed of 51, the product 2 comes into contact with the positioning plate 16 due to a speed difference from the rear positioning plate 16, and is positioned.

  Thereafter, as shown in FIG. 21B, the second lever 64 rotates clockwise, the arm 52 rotates counterclockwise, and the positioning pusher 51 moves upward. Accordingly, as shown in FIG. 21B, the lower end of the positioning pusher 51 is located above the product 2 and the product 2 having the contact specified values aligned with the rear positioning plate 16 is placed on the main conveyor 10. To move forward.

  Furthermore, as shown in an enlarged view in FIG. 22, the inner surface of the side guide plate 28 of the present embodiment has a shape curved inward. That is, the central portion 28a is protruded. This is to prevent the product 2 from being caught by the upstream corner portion 28 b of the side guide plate 28 when turning on the downstream sprocket 25. Therefore, the inner surface of the side guide plate 28 is formed in an arc shape, and its radius of curvature is made to coincide with the rotational radius of the inner surface of the side guide plate 28 around the sprocket 25 when swiveling by the downstream sprocket 25. Yes. Alternatively, the radius of curvature may be set to be smaller.

  Further, according to the apparatus of the present embodiment, since the side of the product 2 is guided by the plurality of side guide plates 28, even if the side guide plate 28 is lifted from the plate 15 due to vibration of the apparatus or the like, the side guide Any one of the plates 28 maintains the state in contact with the plate 15, and the product 2 can be prevented from entering the gap between the side guide plate 28 and the plate 15.

  Further, in the present embodiment, as illustrated, when the positioning pusher 51 is arranged so as to block the front of the product 2, the lower end position of the positioning pusher 51 is the lower surface of the product 2 (the upper surface of the plate 15). However, the present invention is not limited to this, and the positioning pusher 51 enters the space K, and the lower end of the positioning pusher 51 is positioned below the lower surface of the product 2. good. In such a setting, the entire product 2 (particularly, the lowermost article that is in contact with the plate 15) is more reliably contacted and urged toward the rear positioning plate 16 for positioning. Can do. Therefore, for example, instead of bundling a plurality of surfaces as in the present embodiment, it is possible to reliably perform alignment even in the state of individual noodles in the form of loose noodles that are separated and placed on the plate 15 preferable. Further, as in the case of the reverse embodiment, when one bundle has a certain height, such as the long rod-shaped article bundle 2a, or one article has a certain thickness, the lower end position of the positioning pusher 51 Can also be placed at a predetermined distance from the plate 15.

On the other hand, the crossover device 5 is disposed in a space K1 formed between the carry-out end of the conveyance supply device 4 and the bag making device 3a as shown in FIGS. Is done. And as shown as a schematic diagram in FIG. 25, the position of the bottom surface 3a ′ of the bag making device 3a is set to the same height (level) as the position of the transport surface 10a of the main transport conveyor 10 of the transport supply device 4. .

  The plate 15 constituting the conveying surface moves in an arc shape along the diameter of the sprocket 11 together with the attached endless chain 12, and once descends, moves on the return side, and returns to the upstream side. Therefore, the bag making device 3a is arranged at least the radius of the sprocket 11 from the front end of the horizontal conveyance surface, and in the present embodiment, the side guide device 24 (the tip on the downstream side is further than the tip of the main conveyor 10). In other words, a certain margin is actually placed, so that the distance is separated by a certain distance t1 as shown in FIG.

  The crossover device 5 is provided with a strip-like crossover plate 81 extending in a direction orthogonal to the traveling direction of the product 2 and a cylinder 82 for raising and lowering the crossover plate 81 in a space K1 formed by being separated by this distance t1. Configured. FIG. 23 shows a state in which the cylinder rod of the cylinder 82 is housed in the main body and the bridge plate 81 is located at the lowered position. In this state, the crossover plate 81 does not contact the product 2 being transferred from the main transport conveyor 10 to the bag making machine 3a. On the other hand, the cylinder lot protrudes from this state, and the crossover plate 81 moves upward to reach the raised position shown in FIG. This ascending position is a positional relationship in which the upper surface of the crossing plate 81 exists on a line L connecting the front end of the transport surface of the main transport conveyor 10 and the bottom surface 3a of the bag making machine 3a. That is, the conveyance surface 10a of the conveyance conveyor 10, the upper surface of the crossing plate 81, and the bottom surface 3a 'of the bag making device 3a are flush with each other.

  The crossing plate 81 has a taper surface 81a on the rear side (main conveyor 10 side) on the upper surface thereof and a narrow horizontal receiving surface 81b on the front side (bag making device 3a side). And this receiving surface 81b contacts the lower surface of the product 2 currently being transferred from the conveyor 10 to the bag making machine 3a, and prevents further lowering.

  The crossover plate 81 reciprocates between the above-described raised position and lowered position in accordance with the operation of the cylinder 82. And the timing of the raising / lowering operation is as follows. First, at the predetermined timing before the leading end of the product 2 at the top of the main conveyor 10 protrudes from the front end of the conveying surface 10a formed by the plate 15 and reaches the bag making machine 3a side, the jumper plate 81 is positioned at the raised position. To do. In the present embodiment, as shown in FIG. 26 (a), the product 2 has already reached the rising position before the tip of the product 2 reaches the tip of the transport surface 10a, and waits in that state.

  Then, as the conveyance of the product 2 proceeds, the front end of the product 2 protrudes forward from the front end of the conveyance surface 10a, but the transition plate 81 exists between the front end of the conveyance surface 10a and the bag making device 3a. The front end of the product 2 is supported by the connecting plate 81 and can be smoothly passed to the bag making machine 3a side without the front end side being lowered (see FIG. 26B).

  While the product 2 is placed on the plate 15 of the main transport conveyor 10, the product 2 receives a transport force from the main transport conveyor 10. On the other hand, when the tip of the product 2 reaches the bottom surface 3a 'side of the bag making device 3a, the product 2 passes over the bag making device 3a and gets on the packaging film that is formed into a cylindrical shape. And since a packaging film is conveyed according to operation | movement of the pillow packaging machine main body 3, the product 2 riding on the packaging film also receives the conveyance force from the pillow packaging machine main body 3 through the packaging film.

  The product on the bridge plate 81 even if the plate 15 that is in contact with the product 2 tries to move downward in an arc as the sprocket 11 rotates as the conveyance by the main conveyance conveyor 10 further proceeds from the state of FIG. 2 is mostly located on the bag making machine 3a side from the crossing plate 81, and the rear end side of the product 2 does not descend following the descending movement of the plate 15, and from the main conveyor 10 Receives the conveying force at the moving speed of the plate 15 and the positioning plate 16 constituting the conveying surface 10a until the end. Therefore, during the period in which the product 2 receives the conveying force from the main conveyor 10, the braking force is applied by contacting the product 2 and the rear ends of a number of long bar-shaped articles constituting the product 2 remain aligned. It can supply in the bag making machine 3a.

  Then, immediately before the plate 15 leaves, that is, when the conveyance force for the product 2 from the main conveyance conveyor 10 is lost and the product 2 receives the conveyance force only from the pillow packaging machine body 3, the transition plate 81 is lowered. The product is separated from the product 2 and finally the crossing plate 81 reaches the lowered position as shown in FIG. That is, when the crossover plate 81 is in contact with the product 2, it gives resistance to the conveyance of the product 2. Therefore, when the transfer of the product 2 from the main conveyor 10 to the bag making machine 3a is completed, the crossover plate 81 is moved downward so that the crossover plate 81 does not contact the product 2. Therefore, after that, the product 2 moved to the pillow packaging machine main body 3 side moves together with the packaging film, and the packaging film is manufactured by sealing and cutting the appropriate position of the packaging film at a predetermined position.

  In the present embodiment, since the tapered surface 81a is provided on the upper surface of the transition plate 81, even if the side guide plate 28 of the side guide device 24 contacts the transition plate 81, the side guide plate 28 is formed on the tapered surface 81a. It is guided and can move to the outside smoothly.

  In the above-described embodiment, the conveyance supply device 4 is provided with the side guide device 24 so that the width of the product 2 conveyed by the conveyance supply device 4 can be adjusted. However, the present invention is not limited to this. The width cannot be adjusted. Of course, when the width can be adjusted, the configuration is not limited to the above.
