Description

  The present invention relates to an assembly chute for a combination weighing device that automatically weighs articles such as processed foods and frozen foods to a constant weight. In particular, as a preliminary stage for aligning the rod-shaped objects, the rod-shaped objects can be assembled in a horizontal posture. The present invention relates to a collective chute and a combination weighing device using the same.

  As is well known, the combination weighing device is used in various fields as a weighing device that automatically weighs articles having different unit weights to a constant weight. In particular, in the food field, since the characteristics of articles to be handled are diverse, devices suitable for each characteristic have been developed and put into practical use. Among them, stick confectionery or sticks such as frozen fries are arranged in one direction and then stored in a bag or container. For example, in Patent Documents 1 to 4 below, random items discharged from a combination weighing device are used. The rod-shaped object in the direction is converted into the vertical posture by the posture changing device and then stored in the cylindrical container. Patent Document 5 below discloses a technique for converting a rod-shaped object in a random direction into a horizontal posture by rolling a rod-shaped object discharged from the combination weighing device on a U-shaped sheet.

However, in these devices, since the posture changing device that converts the rod-like object in the random direction discharged from the collecting chute of the combination weighing device into the vertical posture or the horizontal posture is installed in the lower stage of the combination weighing device, There is a problem that the height of the entire apparatus is increased by the amount of the posture changing device interposed below the collective chute.
An object of the present invention is to provide a new collective chute that can solve this bulky problem and a combination weighing device using the same.

  The collective chute according to the present invention includes a plurality of chute units formed by connecting a plurality of down-sloped chute surfaces whose lateral width sequentially narrows in the direction in which the rod-like object slides down in the circumferential direction. A collective chute formed as a funnel-like chute as a whole by arranging the chute surfaces in an annular shape inward, and a rod-like object that slides down each chute surface is defined below each chute surface. A twisted portion that is swiveled in the circumferential direction is formed, and a funnel-like chute having a gentle slope is disposed at the lower stage of each twisted portion to discharge the rod-shaped object discharged from each twisted portion while swirling. To do.

  A plurality of hoppers are arranged concentrically above each chute unit arranged in a ring. Then, bar-like objects are discharged all at once from a part of the hoppers weighed by these hoppers and selected in combination to the lower chute unit. Then, the rod-shaped objects facing in a random direction are deflected in the circumferential direction by the lower twisted portion while the longitudinal direction of each rod-shaped object is changed to the sliding direction with less resistance as they slide down the chute surface. And discharged into a funnel-shaped chute. The rod-shaped object discharged in the circumferential direction is discharged in a horizontal posture from a discharge port provided in the center while turning on a gently inclined slope. The discharged rod-shaped object is filled in the lower vibration hopper while maintaining the horizontal posture.

  As a result, each rod-like object can be placed in the horizontal posture in the collecting process by the collective chute without providing the posture change device in the lower stage of the collective chute. Can be lowered.

  Below the discharge port of the funnel-shaped chute, a vibration hopper having a rectangular shape in a plan view is arranged, and the rod-like objects are accumulated in the horizontal posture there. At this time, since the posture of some of the rod-shaped objects may be disturbed, the vibration hopper vibrates vertically and horizontally to align the rod-shaped objects in a substantially horizontal posture. Such a vibration imparting device is also provided in the lower stage of the posture changing device in the conventional device. When a discharge request signal is sent from the lower packaging device, the vibration hopper opens the gate and discharges the rod-like object to the lower packaging device at once.

  In addition, the present invention is a combination weighing device in which the collective chute is incorporated in the lower stage of the hopper device. This combination weighing device is composed of the above-mentioned collective chute, a hopper device installed on the upper stage thereof, and a distributed supply device installed on the upper stage thereof. And a plurality of pool hoppers arranged on the upper stage in correspondence with the respective weighing hoppers. In addition, the distributed supply device individually supplies rod-like objects to each pool hopper. And the rod-shaped object discharged | emitted from the measurement hopper by the combination selection is converted into a horizontal posture in the process of sliding down the collective chute and discharged. Thereby, it can be set as the apparatus which suppressed the height of the whole apparatus lower than the conventional apparatus.

  According to the present invention, since the rod-like object can be converted into the horizontal posture with the collective chute, the posture changing device used so far can be eliminated. Therefore, since the height of the entire apparatus can be kept low, there is an effect that it can be installed even in a factory with a low ceiling. In addition, since the combination weighing device does not need to be installed at a high place, there is an effect that workability such as confirmation of operation status and maintenance of the combination weighing device is improved.

The combination weighing device 1 of this embodiment includes an uppermost distributed supply device 2, an intermediate hopper device 3, a lower collecting chute 4, and a base unit 5 that supports these via support legs 6. Yes.

  The dispersion supply device 2 is disposed on the hopper device 3 to disperse the rod-shaped object supplied from above, and the dispersion table is disposed in the center to disperse the rod-shaped object from the center to the outer periphery. It has a well-known configuration including a plurality of supply troughs arranged radially around the periphery and transporting rod-shaped objects sent from the dispersion table to the tip portion by vibration. Then, the rod-shaped object supplied on the distribution table is distributed to each supply trough by spiral reciprocating vibration or rotational movement of the table, and accumulated there. Then, when the rod-shaped object is discharged from the lower hopper device 3 by the combination selection, the supply trough corresponding to the discharged hopper vibrates for a predetermined time, and supplies the rod-shaped object to the corresponding lower hopper device 3 by an appropriate amount. It should be noted that immediately after the start of operation, since the rod-like object is not supplied to the hopper device 3, the distributed supply device 2 repeatedly operates until the rod-like object reaches the lower hopper device 3.

  The hopper device 3 includes a plurality of pool hoppers arranged annularly along the outer periphery of the dispersion supply device 2, a plurality of weighing hoppers arranged concentrically on the lower stage of each pool hopper, and each of these hopper gates. And a plurality of weight sensors for individually weighing the rod-shaped objects supplied to the weighing hoppers.

  Each pool hopper, when the corresponding lower weighing hopper is empty, opens and closes the gate to discharge the stored rod-like object to the lower weighing hopper. The weight sensor of each weighing hopper detects the weight of the rod-shaped material by weighing the supplied rod-shaped material at a constant cycle. The computer which controls these selects the optimal combination combining each detected weight, and discharges a rod-shaped object from the weighing hopper which concerns on the selected combination. Furthermore, the computer opens and closes the gate of the pool hopper corresponding to the selected weighing hopper, supplies the rod-shaped object to the empty weighing hopper, and then drives the supply trough corresponding to the empty pool hopper. Then, feed the rod-shaped object to the empty pool hopper. The computer repeats such sequence control and executes combination weighing.
