Each is equipped. The objects to be conveyed supplied from the supply feeders 18 and 19 to the inside of the casing 10 are put into the buckets 13 positioned immediately below the supply feeders 18 and 19, respectively. When two types of objects to be conveyed are conveyed by the bucket 13, one type of conveyed object is supplied from the supply feeder 18, and the other type of conveyed object is supplied from the supply feeder 19. Yes. Further, when the bucket 13 to be thrown passes directly under the supply feeders 18 and 19, a hopper (not shown) is opened so that the object to be conveyed is thrown without stopping the driving of the bucket 13. Yes.

  The bucket 13 is attached between a pair of chains 12 as shown in FIG. The bucket 13 is attached by widening the distance between the pair of chains 12 and inserting pins at both ends of the bucket 13 into the chain 12. When the bucket 13 is attached to the chain 12, the posture is maintained by its own weight and the weight of the object to be conveyed.

  As the driving sprocket 14 rotates, the bucket 13 holding the object to be transported moves up in the vertical portion 10b while maintaining its posture, then moves in the second horizontal portion 10c in the horizontal direction, and discharge chute 20 The conveyed object is discharged by rotating upside down and rotating upside down.

  A discharge chute 20 that discharges the object to be conveyed from the bucket 13 is provided at each of the plurality of object discharge positions 20P on the lower surface of the second horizontal portion 10c. In the upper part of the discharge chute 20 that has received a discharge command from the lower weighing device 50, the bucket 13 is turned upside down, and the discharged conveyed object falls through the discharge chute 20 and is arranged below the discharge chute 20. It is delivered to the weighing device 50. In addition, the weighing device 50 combines the received objects to be conveyed so as to have a predetermined weight.

  Each bucket 13 mounted on the chain 12 changes its direction at the terminal sprocket 17, moves horizontally in parallel to the return path at the lower part of the forward path, then changes direction vertically and descends, and again at the position of the drive sprocket 14. The direction is changed in the forward direction, and the conveyed object is continuously conveyed while circulating on the chain 12.

  In addition, two all discharge chutes 25 and 26 are provided on the lower surface of the second horizontal portion 10c. When discharging the objects to be conveyed from all the buckets 13 at the end of the operation of the bucket conveyor 1, the discharge is performed. Similar to the chute 20, the bucket 13 is turned upside down at the upper part of all the discharge chutes 25, 26 to discharge the object to be conveyed, dropped through all the discharge chutes 25, 26, and collected in a container (not shown). It is supposed to be. As understood from the front view shown in FIG. 1 and the side view shown in FIG. 4B, the lower ends of all the discharge chutes 25, 26 are arranged at different positions. When two types of objects to be conveyed are conveyed by the bucket 13, the entire discharge is performed from the bucket 13 that conveys one type of object to be conveyed by the all discharge chute 25, and the other type of object to be conveyed is conveyed. By performing full discharge from the bucket 13 with the full discharge chute 26, it is possible to prevent the varieties of the objects to be transported collected by the full discharge from being mixed.

  An opening / closing door 30 for attaching / detaching the bucket 13 to / from the chain 12, an interlock switch 31 for detecting that the opening / closing door 30 is open, and driving of the chain are started in the vertical portion 10 b of the housing 10. A drive start button 32 for performing an operation, a bucket sensor 33 for detecting the bucket 13, a setting input operation unit 34 for performing an input operation for setting the attachment of the bucket 13, a control unit 40 for controlling the operation of the bucket conveyor 1, Is provided.

  The opening / closing door 30 is opened to form an opening of a size that allows the bucket 13 to be taken in and out of the housing 10 at the attachment / detachment position 30P of the vertical portion 10b, and the bucket 13 can be attached to or removed from the chain 12 through this opening. It is what.

  The interlock switch 31 detects the closed state of the open / close door 30 and allows the control unit 40 to drive the chain 12 only when detecting that the open / close door 30 is closed.

  The drive start button 32 is disposed outside the vertical portion 10b in the vicinity of the open / close door 30 and is operated to start driving the chain 12 in a stopped state in a bucket attachment mode and a bucket removal mode described later. is there.

  The bucket sensor 33 is disposed inside the vertical portion 10b in the vicinity of the opening / closing door 30, and detects the bucket 13 that has moved to the attachment / detachment position 30P where the opening / closing door 30 is provided. The vertical portion 10b includes two pairs of a chain 12 on the forward path side (upward side) and a chain on the backward path side (downward side). The bucket sensor 33 includes the open / close door 30 on the forward path side and the backward path side. May be arranged or configured to detect a bucket 13 on a set of chains 12 on the side that is easy to reach from, or arranged to detect buckets 13 on both forward and return chains 12 Or you may comprise.

  The setting input operation unit 34 is for inputting the required number of buckets in the bucket attachment mode when attaching the bucket 13 to the chain 12, and when the number of objects to be conveyed is one, the required number of buckets. When there are a plurality of types of objects to be conveyed, the number of types of objects to be conveyed and the number of buckets for each type are input. The setting input operation unit 34 includes a keyboard, a touch panel, and the like. From the setting input operation unit 34, for example, input is performed in such a manner that the number of types is “2”, the number of buckets of type A is “20”, and the number of buckets of type B is “10” among the two types.

  The control unit 40 controls the entire bucket conveyor 1, and is a bucket attachment mode that is an operation mode for attaching the bucket 13 to the chain 12 and a bucket that is an operation mode for removing the bucket 13 from the chain 12. The removal mode is to be executed.

  Further, outside the vertical portion 10b in the vicinity of the opening / closing door 30, a mode setting unit 35 that is configured by a keyboard, a touch panel, and the like and sets the operation mode of the control unit 40 to the bucket attachment mode or the bucket removal mode is provided. .

  As shown in FIG. 5, the control unit 40 receives signals from the interlock switch 31, the drive start button 32, the bucket sensor 33, the setting input operation unit 34, the mode setting unit 35, and the connection interface 36, The drive control of the drive motor 15 is performed based on the set operation mode.

  The control unit 40 sets the number of buckets necessary for discharging a predetermined amount of the object to be transported per unit time from the discharge chute 20, and the intervals of the buckets 13 in the chain 12 are equal based on the set number of buckets. The bucket interval is calculated so that Further, the control unit 40 drives and stops the chain 12 for the calculated bucket interval every time the drive start button 32 is operated in the bucket attachment mode, and in the bucket removal mode, the drive start button. The chain 12 is driven and stopped until the bucket sensor 33 detects the next bucket 13 every time the engine 32 is operated.

  Specifically, the control unit 40 calculates the bucket interval so that the intervals of the buckets 13 in the chain 12 are equal based on the number of buckets input from the setting input operation unit 34, or sets the connection interface 36. In order to satisfy the processing capacity of the weighing device 50 acquired from the weighing device 50, the number of buckets necessary for discharging a predetermined amount of the conveyed object per unit time from the discharge chute 20 is set, and the set bucket Based on the number, the bucket interval is calculated so that the intervals of the buckets 13 in the chain 12 are equal.

  When the bucket interval is calculated so that the intervals of the buckets 13 in the chain 12 are equal based on the number of buckets input from the setting input operation unit 34, for example, the number of types input from the setting input operation unit 34 is the type. When the number of buckets for product type A is 20 and the number of buckets for product type B is 10 as shown in FIG. The bucket interval at which the bucket interval on 12 is equal is calculated, and then, as shown in FIG. 6B, the bucket interval at which the bucket interval on the chain 12 is equal is calculated for the type B having a small number of buckets. The “equal” bucket spacing is not strictly equal, but includes “substantially equal”. The total number of bucket mountable positions on the chain 12 is not divisible by the number of buckets to be mounted, and a fraction is generated. In such a case, the control unit 40 allows the bucket interval to be different in part on the chain 12 from others. The control unit 40 calculates the bucket interval so that the bucket interval is uniform between the product type A and the product type B. Similarly, the bucket interval is calculated when the number of types is larger.

  On the other hand, when setting the required number of buckets and calculating the bucket interval so as to satisfy the processing capacity of the weighing device 50 acquired from the weighing device 50 via the connection interface 36, the bucket number is calculated by the bucket conveyor. 1 depends on the discharge supply amount discharged and supplied to the weighing device 50, and this discharge supply amount becomes the required supply amount when viewed from the weighing device 50. The requested supply amount is not the amount actually requested, but depends on the capacity of the weighing device 50. For example, if N objects to be transported combined with Wg can be produced per metering device 50 per minute, the object to be transported is at least Wg × N (pieces) = (W × N) g. You have to keep throwing things in every minute. Actually, if the supply capacity of the bucket conveyor 1 is very low, a sufficient amount of articles cannot be stably supplied to the weighing device 50, so that the combination capability and accuracy deteriorate, and it is conveyed to the weighing device 50 at the start of operation. In order to store things, it is necessary to discharge and supply the object to be transported in a state close to full operation, but at this time, a margin is required for the transport capacity. The amount of allowance may be a constant or may be set. Even when there are variations in the supply amounts from the supply feeders 18 and 19, there is a possibility that the amount of the conveyed object to be supplied may not be sufficiently supplied.

  Specifically, it is necessary to set the discharge supply amount of the bucket conveyor so as to satisfy the following formula: (discharge supply amount of bucket conveyor) ≧ Σ (production capacity of the Kth (natural number) weighing device 50) × margin There is. Here, (the production capacity of the weighing device 50) ≈ (combined weight) × (number of production) / min. When discharging and supplying a different type of conveyed product (in the case of a mix), it is applied to each type. In general, (the discharge supply amount of the bucket conveyor of the number of types L (natural number)) ≧ Σ (the production capacity of the K-th weighing device 50) × the margin.

  In addition, depending on the type of article, a large amount of articles to be transported with one bucket 13 does not enter the bucket 13 so much. Furthermore, since the bucket 13 is not always full and usable, an average bucket capacity is used. This capacity may be set as a weight value according to the product type, or a multiplication factor (coefficient) may be used. The supply amount of the object to be conveyed when the bucket conveyor 1 is in full operation depends on the circulation speed of the bucket 13. Specifically, it can be determined from the number of buckets that can be mounted and the time required for one week of the bucket 13. If the drive speed can be controlled by shifting, the control value may be set to “how many buckets per minute”.

  Information necessary for calculating the number of buckets is how much of the conveyed object is supplied to the weighing device 50, how much of the conveyed object can be supplied by the bucket conveyor 1 at the maximum, and the like. That is, if the required transport amount is half of the maximum capacity, skipping one and attaching the bucket 13 to the chain 12; if 1/3, skipping two and attaching the bucket 13 to the chain 12 Good. In the case of a mix, the position where the bucket 13 can be mounted on the chain 12 is shared by the buckets 13 corresponding to a plurality of types of objects to be conveyed.

  FIGS. 6A and 6B show a case where there are 120 bucket mountable positions on the chain 12. As a result of calculating the bucket interval, the control unit 40 calculates the bucket interval of the product A as 6 In addition, the bucket interval of the product B is set to 12, and allocation is performed so that the bucket mounting planned position of the product B is in the middle of two adjacent bucket mounting positions of the product A. Then, every time the drive start button 32 is operated, the control unit 40 drives the product for the calculated bucket interval so that the planned attachment position of the product type A or product type B moves to the attachment / detachment position 30P where the door 30 is located. The chain is driven and stopped by controlling the motor 15. The chain 12 is allowed to be driven only when the interlock switch 31 detects that the door 30 is closed. Note that a reference position that is detected by contact or non-contact by a sensor (not shown) is set in the chain 12, and the control unit 40 determines the position on the chain 12 based on the detected reference position and the driving amount of the driving motor 15. It comes to grasp.

  Here, when the bucket conveyor 1 is circulated and driven regardless of whether there is a request from the weighing device 50, it is not discharged and supplied to the weighing device 50, and the conveyed product supply position 18P while the conveyed product is stored. , There is a bucket 13 returning to 19P. In other words, when all the buckets 13 return in an empty state, the supply is not in time. At this time, if the further transported object is further supplied, it overflows from the bucket 13, so that the transported object supply positions 18 </ b> P and 19 </ b> P only pass and the transported object is not supplied to the bucket 13. In this way, in order to control whether or not the conveyed object is supplied to the bucket 13 at the conveyed object supply positions 18P and 19P, whether or not the conveyed object is stored in each bucket 13 is stored. It has become. Specifically, whether or not an object to be transported is contained in each bucket 13 is determined by attaching the “attachment / detachment flag” of the bucket 13 to the bucket attachable position on the chain 12 and the “attachment flag”. The position is stored by attaching an “empty / full flag” to the position. When a full discharge operation for discharging all the objects to be conveyed in all buckets 13 from all the discharge chutes 25 and 26 is performed, the “empty / full flag” is reset.

  Further, when the operation mode is the bucket removal mode, the control unit 40 controls the drive motor 15 until the bucket sensor 33 detects the next bucket 13 every time the drive start button 32 is operated, and the chain 12 is Drive and stop. Specifically, when the drive start button 32 is operated, the chain 12 is driven by the drive motor 15, and when the bucket sensor 33 detects the next bucket 13, the drive motor 15 stops and the chain 12 stops. In this state, the user can open the door 30 and remove the bucket 13 from the chain 12. The user closes the door 30 and operates the drive start button 32, so that the chain 12 is driven by the drive motor 15. To move the next bucket 13 to the attachment / detachment position 30P where the door 30 is located. The chain 12 is allowed to be driven only when the interlock switch 31 detects that the door 30 is closed.

  Operation | movement of the bucket conveyor 1 comprised in this way is demonstrated.

  When the mode setting unit 35 is operated and the operation mode is set to the bucket attachment mode, the control unit 40 first calculates the bucket interval so that the intervals of the buckets 13 in the chain 12 are equal.

  Next, the controller 40 controls the drive motor 15 to drive and stop the chain 12 every time the drive start button 32 is operated by the calculated bucket interval.

  On the other hand, when the mode setting unit 35 is operated and the operation mode is set to the bucket removal mode, the control unit 40 causes the bucket sensor 33 to detect the next bucket 13 every time the drive start button 32 is operated. Until the drive motor 15 is controlled, the chain 12 is driven and stopped.

  As described above, the bucket conveyor 1 according to the present embodiment includes the transported object supply positions 18P and 19P at which the transported object is supplied and the transported object discharge position 20P at which the transported object is discharged to the outside. And a plurality of buckets 13 which are provided in the housing 10 and on which the object to be conveyed can be placed are configured to be detachable, and the bucket 13 is connected to the object to be conveyed supply positions 18P and 19P of the chassis 10 An endless chain 12 that circulates between the transported object discharge position 20P, feed feeders 18 and 19 that are provided at the transported object supply positions 18P and 19P and supply the transported object to the bucket 13, and transported object discharge A discharge chute 20 for discharging a conveyed object from the bucket 13 provided at a position 20P, an attachment / detachment position 30P provided on the housing 10 for attaching / detaching the bucket 13 to / from the chain 12, A drive start button 32 that performs a drive start operation of the chain 12, a bucket sensor 33 that is provided near the attachment / detachment position 30P and detects the bucket 13 attached to the chain 12, and a predetermined amount per unit time from the discharge chute 20 Set the number of buckets necessary to discharge the conveyed object, calculate the bucket interval so that the intervals of the buckets 13 in the chain 12 are equal based on the set number of buckets, and operate the drive start button 32 A bucket attachment mode in which the chain 12 is driven and stopped by the bucket interval calculated every time the operation is performed, and the chain 12 is detected until the bucket sensor 33 detects the next bucket 13 each time the drive start button 32 is operated. And a control unit 40 that executes a bucket removal mode for driving and stopping. To.

  With this configuration, the user can feed the chain 12 by pushing the drive start button 32 by the calculated equal bucket interval in the bucket attachment mode, and attach the bucket 13 to the chain 12 at the attachment / detachment position 30P. In the detaching mode, the chain 12 can be sent by pushing the drive start button 32 until the bucket sensor 33 detects the next bucket 13, and the bucket 13 can be detached from the chain 12 at the attaching / detaching position 30P. A to-be-conveyed object can be conveyed, without attaching. Further, since the bucket intervals are equalized, it is possible to shorten the time for conveying the object to be conveyed by the bucket 13 to the discharge chute 20 that has received the discharge command from the lower apparatus. Therefore, it is possible to carry with a necessary and sufficient number of buckets according to the amount of the conveyed object.
