The stopper 12 is released after stopping of movement of the upstream-side conveyor 8 when movement of the container group 2A is stopped by the stopper 12. Thereby, only one row of containers 2 is carried by the downstream-side conveyor 10 to be cut out from the container group 2A and then, one row of containers 2 is shifted on the cutout conveyor 6 by advancing a pusher 14 from backward of one row of containers 2 cut out from the container group.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a container transport device, and more particularly, a container that discharges a group of containers that have been transported on a transport conveyor in a state of being densely packed into a plurality of rows one by one onto a cutout conveyor disposed in a direction perpendicular to the transport conveyor. The present invention relates to a transport device.

  2. Description of the Related Art Conventionally, a container transport device that separates a group of containers that are transported in a plurality of rows by a transport conveyor one by one and then discharges them to a cut-out conveyor is known (for example, see Patent Document 1 to Patent Document 3).

  The container delivery device described in Patent Document 1 includes an introduction conveyor that intermittently conveys containers arranged in a plurality of rows in a direction perpendicular to the row, and a rear row of containers in the first row of the introduction conveyor. Container separating means for separating from the container, and container moving means for discharging the separated one row of containers from a position where the separated containers are transported in the direction of the row to a conveying conveyor.

  In the container delivery device of this Patent Document 1, the release table constituting the container separating means can be moved forward and backward by an air cylinder, and the first row of containers conveyed by the introduction conveyor is a dead plate. Through the release table moving to the introduction conveyor side, the release table moves to separate one row of containers from the subsequent container group, and then the containers on the release table are moved by the container moving means. Discharge onto the conveyor.

  Further, Patent Document 2 discloses a workpiece transfer device that cuts out a bulk of a workpiece supplied to a supply position of an upstream supply conveyor so as to be arranged in a predetermined number of rows by a cutout conveyor and transfers the workpiece to a downstream discharge conveyor. Is described. The cutout conveyor includes a placement portion disposed along the downstream end portion of the supply conveyor, and the placement portion is provided to be shiftable along the conveyance direction of the supply conveyor.

  In the workpiece transfer device described in Patent Document 2, when the bulk first row workpieces that have been transferred by the supply conveyor are placed on the placement portion of the cutout conveyor, the supply conveyor is stopped and cut out. Separate the conveyor placement from the supply conveyor. When the mounting section of the cutout conveyor is cut off from the supply conveyor, the downstream end is connected to the discharge conveyor, and the works arranged in a row are transferred to the discharge conveyor.

  In the container delivery device described in Patent Document 1, since the container moving means slides the container on the release table and discharges it onto the transport conveyor, in the case of a heavy bottle like a bottle, As the drive mechanism becomes large, there is a problem that the bottom surface of the bottle is damaged.

  In the workpiece transfer apparatus described in Patent Document 2, the placement unit of the cutout conveyor moves to open a space between a row of containers and a succeeding container, so when handling heavy containers such as one bottle The mechanism that slides the placement section of the cutout conveyor is a major factor. In addition, as described in paragraph “0082” of Patent Document 2, when the mounting portion of the cutout conveyor is separated from the supply conveyor, the workpiece may fall over, or some of the workpiece may straddle the supply conveyor and the cutout conveyor. There is a problem that a transport trouble is likely to occur and the stability is insufficient.

  In the configuration of the invention described in Patent Document 3, the take-out fingers are lowered and engaged with the containers and transferred to the discharge conveyor by horizontal movement, and the take-out fingers are inserted into the dense containers, so that the containers are aligned. When there is a disorder, there is a problem that there is a risk that the container collides with the container and is damaged.

  The present invention has been made in order to solve the above-described problem, and a transport conveyor that transports a group of containers arranged in a plurality of rows in a direction orthogonal to the rows, and a transport direction of the transport conveyor downstream of the transport conveyor. In a container transfer device that is arranged in an orthogonal direction and includes a cutout conveyor that receives and transfers a row of containers, the transfer conveyor is separated into an upstream conveyor and a downstream conveyor. Each conveyor can be driven and controlled, and when the top row of containers transported by the upstream conveyor is transferred to the downstream conveyor, it is stopped by abutting against this row of containers and transported by the downstream conveyor. A pusher that engages with the rear surface of the row of containers formed and cuts the containers and transfers them onto a conveyor. When one row of containers is stopped, the operation of the upstream conveyor is stopped, and then the stopper is released and the row of containers is transported by the downstream conveyor to be separated from the subsequent containers. One row of containers is cut out and transferred onto a conveyor.

  In addition, a second invention provides a driving means for moving the stopper to the downstream side in the first invention, and after stopping a row of containers transferred to the downstream conveyor by the stopper, the stopper is moved downstream. A gap is formed between the one row of containers moved to the side and the first row of containers on the upstream conveyor, and further, a detecting means for detecting whether or not a container exists in the gap is arranged, When the container is detected by the detection means, it is determined that the abnormality is present.

  When only the first row of containers in the container group is transferred from the upstream conveyor to the downstream conveyor, the container group is stopped by the stopper, and then the upstream conveyor is stopped and the stopper is released to Since the containers are separated and then the separated containers are pushed into the cutout conveyor by the pusher, the group of containers can be surely cut one by one and transferred to the cutout conveyor. In addition, the overall structure of the apparatus is simple, and even when handling a large container such as a bottle, the conveyance stability is high and the container is not damaged.

Fig.1 (a) is a top view of a container conveying apparatus, (b) is a side view. (Example 1) FIG. 2 is a plan view of a configuration in which the stopper and the pusher are moved up and down and advanced and retracted. FIG. 3 is a side view of a configuration in which the stopper and the pusher are moved up and down and advanced and retracted. FIG. 4 is an enlarged view showing a main part of a configuration in which the stopper and the pusher are moved up and down and advanced and retracted. FIGS. 5A to 5F are diagrams for sequentially explaining the operation of the container transport device. 6 (a) to 6 (e) are diagrams for sequentially explaining the operation of the container transport device, and are diagrams following FIG. 5 (f).

  This is a container transport device that separates a plurality of rows of container groups transported in a dense state by a transport conveyor one by one, and transfers them onto a cut-out conveyor disposed in a direction perpendicular to the transport conveyor. When the containers to be transported are arranged in a staggered pattern, they cannot be transferred to the cutting conveyor unless they are surely separated one by one. Therefore, the present invention divides the transport conveyor into an upstream conveyor and a downstream conveyor, and stops a container group that has been transported, and a container that cuts out the containers separated by a row and transported by the downstream conveyor. A pusher that pushes upward is provided.

  The stopper and pusher are lowered positions that can be engaged with the container, and can be moved from the retracted position to the advanced position, and can be moved from the lowered position to the raised position at the advanced position. It moves from the position to the retracted position and can descend again at the retracted position.

  When the stopper is in the retracted position at the lowered position, the container group conveyed by the upstream conveyor hits the stopper and stops with only the first row of containers transferred onto the downstream conveyor. In this state, the upstream conveyor is stopped and the stopper is advanced. Only the row of containers that have been transferred onto the downstream conveyor moves to the position of the advanced stopper, creating a gap between this row of containers and the subsequent group of containers that are riding on the upstream conveyor. Thereafter, when the stopper is raised, only the first row on the downstream conveyor in the container group is separated from the subsequent container group and conveyed.

  When the row of containers conveyed by the downstream conveyor reaches the downstream end of the downstream conveyor, the pusher that has risen at the retracted position and has been waiting upward is lowered. When the pusher descends in the retracted position, it is positioned behind the row of containers. By advancing in this position, the pusher engages the back of the container and pushes it out of the downstream end of the downstream conveyor and transfers it onto the cutout conveyor.

  Hereinafter, the present invention will be described with reference to embodiments shown in the drawings. In this container transport device, the container group 2A (the entire assembled container 2 is indicated by 2A) arranged in a plurality of rows (the vertical alignment in FIG. 1a is called a row) is orthogonal to this row (see arrow A). The transport conveyor 4 that transports the container 2 and the container 2 in the first row of the container group 2A that has been transported by the transport conveyor 4 are cut off from the rear container group 2A, and then the container array is received and transported in the direction of the array And a conveyor 6. In this embodiment, the circular containers 2 are conveyed by the conveying conveyor 4 in a staggered arrangement (an arrangement in which one row of containers 2 is positioned between the adjacent rows of containers 2). After the containers 2 conveyed by the above are separated one by one, they are transferred to the cutting conveyor 6.

  In this embodiment, in order to separate the container group 2A that has been transported in a plurality of rows by the transport conveyor 4 one by one and deliver it to the cutout conveyor 6, the transport conveyor 4 is divided into an upstream conveyor 8 and a downstream conveyor 10, A stopper 12 for separating the one row of containers 2 transferred from the upstream conveyor 8 to the downstream conveyor 10 from the subsequent container group 2A, and the containers 2 separated by one row and conveyed by the downstream conveyor 10 A pusher 14 for transferring to the cutting conveyor 6 is provided.

  The upstream conveyor 8 and the downstream conveyor 10 constituting the transport conveyor 4 have independent drives, and the drive can be controlled independently. The upstream conveyor 8 is intermittently operated with on / off control of driving. On the other hand, the downstream conveyor 10 always operates. The downstream end of the upstream conveyor 8 and the upstream end of the downstream conveyor 10 are arranged close to each other, and the containers 2 conveyed by the upstream conveyor 8 can be transferred to the downstream conveyor 10 as they are (FIG. 1). (See (b)).

  Guides 16 are arranged from both sides of the upstream conveyor 8 to the upstream end of the downstream conveyor 10, and both sides of the container group 2A to be conveyed are guided. There is a slight gap between the downstream end of the downstream conveyor 10 and the cutout conveyor 6, and a transition plate 18 for transferring the container 2 to this gap is disposed.

  Further, the cutout conveyor 6 is operated intermittently by controlling the driving on and off, and receives a row of containers 2 from the downstream conveyor 10 by the pusher 14 during the stop, and the direction of the row (arrow B) Refer to A guide 20 that supports the container 2 pushed by the pusher 14 is provided on the side opposite to the downstream conveyor 10 of the cutout conveyor 6 (left side in FIG. 1A).

  As shown in FIG. 1 (b), the stopper 12 is arranged above the downstream conveyor 10, and is located between a lowered position where the stopper 12 can come into contact with the body of the container 2 and a raised position where the stopper 2 does not come into contact with the container 2. Can be moved up and down. Further, the stopper 12 is located at a position slightly downstream of the retracted position from the position (retracted position) where the stopper 12 is in contact with the front surface of the container 2 for one row transferred from the upstream conveyor 8 to the downstream conveyor 10. It can be moved to (forward position). Further, the stopper 12 can be retracted by the same distance as the distance advanced at the lowered position at the raised position.

  The pusher 14 is disposed above the downstream side of the downstream conveyor 10 and can move up and down between a lowered position that can be engaged with the body of the container 2 and an elevated position that is not engaged with the container 2. . Further, the pusher 14 is engaged with the rear surface of the row 2 of containers 2 from the position (retracted position) facing the rear surface of the row of containers 2 being conveyed by the downstream conveyor 10 at the lowered position. It can move to a position (advance position) to be pushed onto the conveyor 6. Further, at the ascending position, it can be retracted by the same distance as the distance advanced at the descending position.

  The conveyor 4 (especially the downstream conveyor 10) is provided with a plurality of sensors to detect the presence of the container 2 being conveyed and the absence of the container 2. In addition, since description of a sensor is abbreviate | omitted in FIG. 1 (a), (b), it demonstrates with FIG. 5 (a). The first sensor 22 provided at the upstream end of the downstream conveyor 10 is located between the first container 2 of the container group 2 </ b> A transferred from the upstream conveyor 8 to the downstream conveyor 10 and the containers 2 in the second row. When the first sensor 22 does not shield the light after the stopper 12 described later performs a predetermined operation (advance after stopping the container 2 at the lowered position), it is normal. Assuming that the operation is being performed, the following operation is performed. If the stopper 12 is shielded from light even though the predetermined operation has been performed, it is determined that an alignment abnormality has occurred in the container group 2A for some reason, the operation is stopped, and the operator solves the abnormality. To do.

  Further, the second sensor 24 is located slightly downstream of the first sensor 22 (on the downstream side by a distance approximately one half of the width of the container 2 in the front-rear direction of the container 2 (the diameter of the round container 2 in this embodiment)). Has been placed. The second sensor 24 detects that the top row of the container group 2A conveyed by the upstream conveyor 8 has reached the stopper 12 that is retracted at the lowered position. Furthermore, the stopper 12 moves to a position slightly downstream of the second sensor 24 (downstream side slightly away from the first sensor 22 in the front-rear width of the container 2) as the stopper 12 advances in the lowered position. A third stopper 26 is provided at a position shielded from light by the container 2 that has been removed. When the first sensor 22 is shielded from light, the third sensor 26 is not shielded from light. Conversely, when the third sensor 26 is shielded from light, the first sensor 22 is not shielded from light.

  A fourth sensor 28 is disposed at the downstream end of the downstream conveyor 10. When this fourth sensor 28 is shielded from light and detects that the container 2 has reached the downstream end of the downstream conveyor 10, the pusher 14 that has been raised in the retracted position is lowered and positioned on the rear side of the container 2. By moving forward in the lowered position, one row of containers 2 is pushed out and transferred onto the cut-out conveyor 6 via the transition plate 18.

  Next, a configuration for moving the stopper 12 and the pusher 14 up and down and forward and backward will be described with reference to FIGS. Two rotating shafts 32 and 33 in a direction orthogonal to the conveying direction of the conveyor 4 (see arrow A) are supported in parallel on the upper and lower wall surfaces 30 a and 30 b of the machine frame 30. These two rotating shafts 32 and 33 are rotated by separate motors 34 and 35, respectively. The right side of FIG. 2 is a motor 34 and a rotary shaft 32 for driving a stopper, and the left side is a motor 35 and a rotary shaft 33 for driving a pusher.

  A short intermediate shaft (intermediate shafts 36 and 38 for the stopper 12 and an intermediate shaft for the pusher 14) respectively supported on both side walls 30 c and 30 d of the machine frame 30, approximately at the intermediate portion between the two parallel rotating shafts 32 and 33. 37, 39). Driving belts (stoppers) are attached to pulleys 40, 42, 44, 46, 41, 43, 45, 47 provided at both ends of the rotary shafts 32, 33 and ends of both side intermediate shafts 36, 38, 37, 39, respectively. Driving belts 48, 50 and pusher driving belts 49, 51) are wound around, and the driving belts 48, 50, 49, 51 reciprocate in the horizontal direction by driving the motors 34, 35.

  Timing belt pulleys 52, 54, 53, 55 are attached to the opposite sides of the pulleys 44, 46, 45, 47 of the driving belts 48, 50, 49, 51 of the intermediate shafts 36, 38, 37, 39. ing. Driven pulleys 56, 58, 57, 59 (see FIGS. 3 and 4) obliquely below these pulleys 52, 54, 53, 55 are provided, and the upper pulleys 52, 54, 53, 55 and the lower pulleys are provided. Timing belts (stopper timing belts 60 and 62 and pusher timing belts 61 and 63) are wound around the driven pulleys 56, 58, 57 and 59. These timing belts 60, 62, 61, 63 reciprocate in the up-down direction slightly inclined as the driving belts 48, 50, 49, 51 travel in the horizontal direction. The upper portions of the stopper timing belts 60 and 62 are inclined forward (downstream in the transport direction), and the pusher timing belts 61 and 63 are inclined upward (backward in the transport direction).

  Fixing plates 68, 70, 69, 71 facing the transport direction A of the transport conveyor 4 are fixed to the timing belts 60, 62, 61, 63 via brackets 64, 66, 65, 67, As the timing belts 60, 62, 61, 63 move, the mounting plates 68, 70, 69, 71 move up and down. Up and down rails 76, 78, 77, 79 are provided on the fixing members 72, 74, 73, 75 fixed to the side walls 30c, 30d of the machine frame 30, and sliders 80, 82 are provided on the brackets 64, 66, 65, 67, respectively. 81, 83 are fixed and fitted to the rails 76, 78, 77, 79 in the vertical direction, and the mounting plates 68, 70, 69, 71 of the timing belts 60, 62, 61, 63 are driven. Guides up and down.

  Between the timing belts 60, 62, 61, 63 arranged on both sides in the conveying direction, the mounting bar 88 in the direction crossing the lower conveying conveyor 4 via the fixing plates 84, 86, 85, 87 at both ends. , 89 are connected, and the stopper 12 and the pusher 14 are attached to the attachment bars 88, 89, respectively.

  A stopper lateral movement cylinder 90 is fixed to one of the stopper mounting plates 68 and 70 on the both sides in the conveying direction (downward in FIG. 2), and the fixing plate of the mounting bar 88 is fixed to the piston rod 90a of the stopper lateral movement cylinder 90. 86 is fixed. Further, a horizontal rail 92 is fixed to the other 68 (upper side in FIG. 2) of the stopper mounting plate. The slider 94 is fixed to the fixing plate 84 of the mounting bar 88 and is fitted to the horizontal rail 92. Accordingly, the timing belts 60 and 62 travel obliquely in the vertical direction as the driving belts 48 and 50 travel, and the stopper 12 moves up and down accordingly. In addition, the stopper 12 moves back and forth in the transport direction (arrow A) of the transport conveyor 4 by the operation of the stopper lateral movement cylinder 90.

  A pusher lateral movement cylinder 91 is fixed to one of the pusher mounting plates 69, 71 on the both sides in the transport direction (upward in FIG. 2), and a fixing plate for the mounting bar 89 is fixed to the piston rod 91 a of the pusher lateral movement cylinder 91. 85 is fixed. In addition, a horizontal rail 93 is fixed to the other 71 (downward in FIG. 2) of the pusher mounting plate. A slider 95 is fixed to the fixing plate 87 of the mounting bar 89 and is fitted to the horizontal rail 93. Therefore, in the pusher 14, the timing belts 61 and 63 travel obliquely in the vertical direction as the driving belts 49 and 51 travel, and ascend and descend accordingly. Further, the pusher 14 moves forward and backward in the transport direction of the transport conveyor 4 by the operation of the pusher lateral movement cylinder 91. The stopper 12 moves laterally at the lowered position (advances in the conveying direction) to separate the one row of containers 2 from the subsequent container group 2A, whereas the pusher 14 moves laterally at the lowered position (advances in the conveying direction). ), The container 2 on the downstream conveyor 10 is cut out and pushed out to the conveyor 6, and the pusher 14 is moved laterally longer than the stopper 12 (see FIG. 3).

  The operation of the container transport device according to the above configuration will be described with reference to FIGS. As described above, during the operation of the container transport device, the upstream conveyor 8 of the transport conveyor 4 is intermittently operated by the on / off control, and the downstream conveyor 10 is always operated. The cutting conveyor 6 is intermittently operated by on / off control. At the start of operation, as shown in FIG. 5A, the stopper 12 is lowered at the retracted position, and the pusher 14 is elevated at the retracted position. The stopper 12 and the pusher 14 can move forward and backward in the transport direction A of the transport conveyor 4, and an upstream position is referred to as a backward position and a downstream position is referred to as a forward position. In order to explain the operation of the stopper 12 and the pusher 14, the retracted position at the lowered position is 12A, 14A, the advanced position at the lowered position is 12B, 14B, the advanced position at the raised position is 12C, 14C, The retracted position at the raised position will be described with reference numerals 12D and 14D.

  As shown in FIG. 1A, the round container 2 is conveyed in a state where the upstream conveyor 8 is in close contact with the front, rear, left and right in a staggered arrangement (this state is referred to as a container group 2A). . The first row of containers 2 in the container group 2A reaches the stopper 12 (12A), and the entire container group 2A stops. In the state where the container group 2A is stopped at the position where the stopper 12 is lowered, only the first row of the container group 2A conveyed by the upstream conveyor 8 is transferred onto the downstream conveyor 10, and the second and subsequent rows are It rides on the upstream conveyor 8 (see FIG. 2A). The second sensor 24 detects that the top row of the container group 2A has reached the stopper 12. When a certain time (for example, 3 seconds) elapses after being detected by the second sensor 24, a control unit (not shown) stops driving the upstream conveyor 8. By operating the upstream conveyor 8 for a certain period of time after the top container 2 is stopped by the stopper 12, the row of containers 2 that are in contact with the stopper 12 can be aligned on a straight line.

  The container group 2A is stopped by the stopper 12A that is retracted at the lowered position, and the stopper 12 is advanced after aligning the first row of containers 2 with each other. Since the container 2 in the first row rides on the downstream conveyor 10 that is always operating, and the container group 2A in the subsequent second row rides on the stopped upstream conveyor 8, the stopper 12 (advance position) 12B), the first row of containers 2 moves forward and a gap is formed between the second row and subsequent container groups 2A (see FIG. 2B). When the first row of containers 2 moves forward with the stopper 12B and stops, the third sensor 26 is shielded from light and it is detected that the container 2 has reached the position of the advanced stopper 12B. At this time, the first sensor 22 is not shielded from light, and it is detected that there is a gap between the first row of containers 2 and the second row of containers 2. As described above, when the third sensor 26 is shielded from light and the first sensor 22 is not shielded from light, it is determined that a normal operation is being performed and the next operation is performed. When the first sensor 22 is shielded from light, it is determined that an alignment error of the container 2 has occurred for some reason, and the operation is stopped.

  Next, the stopper 12B moving forward at the lowered position is raised. When the stopper (moved to the forward ascending position 12C) is raised and disengaged from the containers 2, the one row of containers 2 is conveyed downstream by the downstream conveyor 10 that is always driven (FIG. 5 (c). )reference).

  While the one row of containers 2 is being conveyed by the downstream conveyor 10, the stopper 12C raised in the advanced state moves to the retreat position 12D (see FIG. 5D).

  When the stopper 12D is lowered at the retracted position (the stopper is moved to the lowered position 12A at the retracted position) and can be engaged with the container 2 (see FIG. 5E), the upstream conveyor 8 is driven. The container group 2A is transported again. The second row of containers 2 (the first row of containers in the subsequent container group 2A) reaches the stopper 12A and stops (see FIG. 5 (f)). The containers 2 in the first row are conveyed by the downstream conveyor 10, and the container group 2A after the containers 2 in the second row is in the same state as in FIG.

  The second sensor 24 detects that the first container 2 of the container group 2A has reached the stopper 12A, and after the predetermined time has elapsed, the drive of the upstream conveyor 8 is stopped, and then the stopper 12A is advanced (to the advance position 12B). . As the stopper 12B moves forward in the lowered position, the container 2 riding on the downstream conveyor 10 moves forward together with the stopper 12B and stops, and there is a gap between the container 2 and the subsequent container 2 (container group 2A in the third and subsequent rows). (See FIG. 6A). At this point, the first row of containers 2 is being transported on the downstream conveyor 10.

  When the first sensor 22 detects that there is a gap between the one row of containers 2 on the downstream conveyor 10 and the top container 2 of the container group 2A on the upstream conveyor 8, the stopper 12B is raised. (The stopper moves to the raised position 12C at the forward position), and conveys the one row of containers 2 that have been stopped (see FIG. 6B). On the other hand, when it is detected by the fourth sensor 28 that the preceding first row of containers 2 (the leftmost container 2 in FIG. 6B) has reached the push-out position, the pusher 14D that has been lifted at the retracted position. Descends (the pusher 14 moves to the lowered position 14A at the retracted position).

  In the retracted position, the pusher 14 </ b> A is in a position where it does not interfere with the container 2 detected to have reached the downstream end by the fourth sensor 28, and descends to a position slightly behind the first row of containers 2. Thereafter, the pusher 14A is moved forward with the lowered position (the pusher 14 moves to the advanced position 14B at the lowered position). The pusher 14 pushes the row of containers 2 from behind and passes over the crossing plate 18 to transfer onto the cutting conveyor 6 (see FIG. 6C).

  The stopper 12 is lowered and moved downward (the stopper 12 moves to the retracted position 12D of the raised position) while the container 2 that has been disengaged by being lifted is transported and passes below, and then lowered. The position returns to the position 12A where the container 2 on the downstream conveyor 10 can come into contact (see FIG. 6D). When it is detected that the stopper 12A is lowered, the driving of the upstream conveyor 8 is resumed and the subsequent container group 2A is conveyed.

  The containers 2 transferred from the downstream conveyor 10 to the cutout conveyor 6 by the pusher 14 are transported to the downstream side when the cutout conveyor 6 is driven. Further, as shown in FIG. 6C, the pusher 14 rises at the forward position (the pusher 14 moves to the forward position 14C). On the other hand, on the stopper 12 side, the container group 2A advances by driving the upstream conveyor 8, and the first row of containers 2 rides on the downstream conveyor 10 and is stopped by the stopper 12A (see FIG. 6 (e)). In the same manner, the container group 2A on the conveyor 4 is moved one by one by driving and stopping by raising and lowering and advancing and retreating the stopper 12 and the pusher 14, and on / off control of the upstream conveyor 8 and the cutting conveyor 6. Cut out, transferred onto the cutout conveyor 6 and conveyed downstream.
